"Heli" fying at Cowra (Ian)

Helicopter pilots seem to be taking over CMAC at present. Mark, a new member who is very keen has teamed up with Matt to fly at the field most weeks. Several other members who have dabbled in the past are now getting enthusiastic again. We seem to have reached a critical mass of helicopter expertise and who knows where this will lead the club in the future. Certainly the entry-level costs are relatively cheap. While some toys do not really provide long-term satisfaction they still serve as a important entry point into the sport.

As you can see in the pictures, that doen't mean we don't fly other models including control liners . All forms of model flying are great fun and should be encouraged.

Don't forget the 'Oily Hand Diesel day is just around the corner (August 28-29th).For the events flier click here Oily Hand Diesel Day

CL "non-combat" at Cowra (Ian)

Over the last few weeks we have been really enjoying our late afternoon CL sessions. The Luckett's Sabres are now a bit war-weary and Matts "Plank" is missing about 20% of its outermost wing. Despite this it still flies well. I have also had to replace numerous needle valves due to untimely upside down 'landings'. One of the best sessions we had involved Andy and Owen attempting a bit of CL combat with their 'Sabres'.Hence their war-wounds caused by flying into the ground while trying to avoid the other aircraft.

No easy feat this "combat". After a few rounds we decided it might be best just to try to fly two aircraft in the same circle WITHOUT hitting each other. This was not as easy as it seemed either and was just as nerve-wracking to watch from the sidelines. Just as much fun as 'full-on' combat at this stage.

However the Sabres are just about worn-out and we will probably need a building program soon to keep them in the air and 'non-combat' on the go.

In the mean time I have been putting a "Plank" togther although Mat reckons it's taking way too long as he slapped his togther in a night! The greatest delay has been caused by a lack of balsawood as I didn't have any in the right sizes. Local toyworld stores in the area didn't have any stock in the right sizes that were hard enough for the job and wern't too interested in getting any more in. Another bigname model supplier also didn't have any and said he was mostly into ARFs these days anyway. Finally 'Bunnings' came through with the goods. Although it is also a bit on the light side I can't wait any longer. Looks like Balsa is becoming a specialist item these days!

Control line simplicity (Ian)

After we have finished radio flying for the day we have been getting the 'control-liners' out to fly-away the last half hour or so of daylight. Aeromodelling doesn't get much simpler or better than CL. Small-cost, small-risk but huge buzz-factor and we all go home pretty happy with ourselves. CL seems to be going through a bit of a resurgance of interest these days. Certainly there is plenty of competition on eBay for anything CL and you can get many modern engines (both 2 and 4 stoke, glow and diesel) in CL versions. There are also ARF CL models too.

On the other hand you don't need to go out and buy new stuff. If you have a couple of old engines and set of wires at home (or can srounge them off someone else) you can make something very cheaply that will put a smile on your face.

Andy has been flying his fleet of well patched 'all sheet' Cox 049 Sabres as well as a Fox 29 powered Hearn's 'Demon. I have been flying a Sarpoulos 'Little Brother' powered by an AM10 and a OS25 powered 'Blaze' from Aeromodeller plans. Matt's model which has become known as 'The Plank' was put together and fuel proofed in a single evening. This is not hard to believe but despite its simple lines it flies well. It does inside and outside loops, extended inverted flight, lazy eights etc. with ease. Both the Sabres and Matts 'The Plank' bounce when they crash and are soon back in the air. This is just as well because Andy has been perfecting his 'number 9 manouvre' (a 3/4 loop followed by a vertical landing). While the other models are great they take a bit more to fix, which is why we don't take the same risks with them as we do the simpler designs and as a result don't seem to get quite as much enjoyment or satisfaction from them.

The moral of the story is if you want to maximise flying time and adrenaline...keep it simple. A photos of Matts plane is included to inspire you.

Randle Goes West (Andy)

We had a visit from good mate Jeremy Randle during the third week in April. Jeremy chose the most perfect autumn weather Cowra has to offer. Still, warm sunny days – designed for flying. We spent Wednesday evening with Ian Cole preparing models and swapping ideas, news and lies.

Thursday morning saw us at River Park with Ian’s Sopwith Pup, Jeremy’s little Parkzone Sukhoi and and aged TD3 Cap. Great mornings flying capped off at a local coffee shop. After lunch we headed to the field. I had my good friend the Fourstar and my Adrenaline plus a couple of C/L models.

Jeremy had his Mega brushless powered Stryker. This is an incredible performer which has been in Jeremy’s stable for years. He also had a Multiplex Easy Star motor-glider which is a testbead for different motor, prop, battery and controller combos. Fitted on board is a GPS and data logger which records data throughout the flight which can then be downloaded to a laptop to analyse performance of differing combos. Ian bought out his Irvine 61 powered Phoenix Tiger 60 and his little Pup so it could play with the big dogs out at the field.
Andy's trusty Adrenaline - not sure about the pilot though. Jeremy and Ian flying the Stryker
Ian's open mouth says it all I think.

Matt Robson came down at afternoon teatime for cake and a cuppa. He bought along his rough and ready “Plank “(apt description) control liner. Everyone had a fly and as the sun sank in a ruddy glow below the horizon yours truly managed to do a number nine and break the prop. That meant it was time to end an excellent day and head home. Looking forward to the Randle chappie finding time to come and visit again sometime.


Aerial video on a tight budget (Ian)

A friend put me onto these little units that are available off ebay suppliers as an "808 key chain camera" for around $20. For that price I decided to give it a go. After several weeks I can say that I am really happy with it and despite a few teething problems it has worked reliably.You do need to budget for a 2-4gb micro sd card (mine cost $12).


The 808 key chain camera

The main problem was the instructions. The english translation was not clear and some vital bits were missing. Thankfully the internet came to the rescue and everthing now works as it should.(for more information see http://www.chucklohr.com/808/#raisethedeadone)

Having tried it out over several weeks on a GWS pico moth I consider it a sucess.The beauty of it is it size. It's so light and small you can put it on small vehicles such as Bell, Lama or Blade2 type indoor helis or the GWS foam pico moth or cub types. Picture quality is surprisingly good! 2-3 minute translates to about 200mb (and anything longer is a bit boring anyway).The video clip below is about 47mb.

The Pico moth camera plane
with velcro camera mounts>
The landing looks rough but the grass was a bit long!

Best location for the camera seems to be either looking back over the tail or forward to the side (avoiding the prop) pointing about ~15-30 degrees down. If you get the prop in the image it puts a series of horizional lines across the image. The GWS moth is a very nice platform because it’s light and you can mount it in either front or rear cockpit or on the wing center section.

On the down-side the pico moth gets blown around even in mild conditions. Calm on the ground is not always calm at 30m AGL though this is not a huge problem if you choose the right time.




Timing Laser 4 stoke engines (Ian)

Maybe everybody already knows this but I didn't and had to work it outwith a bit of help from a good mate. I have replaced bearings in lots of engines over the years. Many were 'bargains' picked up off ebay! ASP and OS types are not really a problem. All you have to do is make sure the timing mark on the helical gear on the camshaft is aligned with the pushrod tubes when the propdriver mark indicates Top Dead centre (TDC). It takes a couple of goes but its not too difficult to get it right. Laser engines are completely different to this in that the cams and pushrods are at the rear of the engine driven off the crankpin via a separate shaft. When you dissassemble the engine to replace the cam drive shaft bearing the timing is lost. There are no timing marks or or even a TDC mark to use on reassembly.

Unlike the OS engines you can't just take the rear crankcase cover off to check crank position either (see photos).One approach is to take photos before disssasembly and try to put the cams back in the same position. I tried this but wasn't too confident I'd got it right. Then Andy suggested I use a timing-disc.I tried it and it worked really well.

The photos below tell the story.

The engine is mounted on two pieces of aluminium angle. Two school protractors (cost 50c each) are drilled out and fastened to the prop driver using the prop nut and suitable spacer. TDC is determined by inserting either a dial gauge or a small probe down the glow plug hole. The protractor was then adjusted until the 180 degree mark and TDC coincided with the top right hand face (looking from the back) of the aluminium angle.
The $1 timing-disc marked in red at 40 degrees before TDC, TDC (red dot), 30 degrees after TDC
and direction of rotation

The instructions for the Laser 150 indicate that the inlet valve should start to open at 40 degrees before TDC. This is achieved by turning the engine over until the protractor indicates 40 degrees before TDC and then placing the cam so that it is just starting to lift the cam follower. I found it easier to remove the rocker by undoing the single retaining bolt and sliding the rocker shaft out rather than removing the 5 cylinder head bolts. The exhaust cam is set in a similar way so that the cam follower bottoms out with the disk positioned at 30 degrees after TDC . A dial gauge on the rocker arm above the valve as a final check showed the settings to be spot on.

setting inlet valve cam (LHS) at
40 degrees BTDC
TDC (note red dot on disc is aligned with top of aluminium angle) setting exhaust valve cam (RHS) at
30 degrees ATDC

Is all this really necessary? While the photographic method probably would work I certainly felt happier using the timing-disc method. When you think of it the cam gear only has 24 teeth so one tooth out = a whopping 15 degrees. With practice you probably would detect this by eye. On the other hand the timing-disc cost me almost nothing and next time will be even easier.


Doesn't time fly: apologies! (Ian)

Have just had a look at the website - last updated in November 2008!- Where does the time go. As a good friend of mine (ML) says 'work is the curse of the modelling classes' and he's right; work can certainly get in the way of some aeromodelling ambitions some times. Then again no work means no money, which also puts a bit of a constraint on activities. Well what has been going on? Flying activity at Cowra MAC diminished over December-January as family and seasonal festivities ate into aeromodelling time. But things picked up in February and apart from bad weather there has been someone out flying most Sundays. The club catered for the SAMs Old timer event at Canowindra over the Easter weekend and Andy reperesented the club at the inaugural 'Warbirds for dummies' event at Dubbo MAC. So its been business as usual really. Its just that I have been a bit slack in the website area and need to get my act together again.

Round the pole (RTP) flying (Ian)

RTP is a type of flying that I often read about as a youngster but never got around to doing till recently. All sorts of models are capable of being flown RTP including multi-engine, ducted fan and flying boat (off shallow plastic lined pools). It is supposedly possible to perform loops and some brave souls have even engaged in combat events.Aeromodeller adverts used to feature a UK company called 'Ballards' but the specialist items were never available in Australia till I managed to source a few items from a Tasmanian company called 'RTP Electrix' which I believe has now closed down. Two simple profile Mitsubishi 'Zero' models were built and flown using slot-car type speed controllers and a 12 v battery. This worked, but only just. 24Volts was really exciting but started to cause a melt-down down in the controller resistors which got rather hot and started to smoke (a lot). We are now experimenting with some simple transistorised speed controllers of our own design which seem to peform okay so far.

So what's so great about flying around in circles. Well firstly it's something different that may turn out to be a great youth group or boys club activity. One educational site (http://www.ctie.monash.edu.au/hargrave/mccarthy_rtp.html) (just click here) has promoted it as a school activity to teach the basic physics of flight, aircraft construction and design . Besides this it is more challenging than you first imagine and can be quite addictive. You see it's not as easy as you may think because there is no elevator; the only control you have is throttle, so it all depends upon the setup of the particular model and the skill of the pilot. Add low ceiling beams and another model in the circle (we can fly two models at the same time) and it gets exciting. our first session ended when one 'Zero' tryed to overtake the other almost chopping it in half, so we know how to do combat! But how people have aerobatted them I have no idea but am keen to find out. Perhaps we can learn from others with more experience on the Saturday night get together.

The images below show the 'victorious' Zero and the RTP centre pole that we use. In the next week or so I will also make a link to a short video clip taken by Andy during a recent flying session.

Marulan pylon racing: November 2008 (Andy)

These are from the last round of the NSW Pylon Racing Champs held at Marulan. A few of the fliers went down a day early to get a bit of social flying in. We had a ball.

The photo above is of Ranjit Phelan and his SkyRaider hoon plane. Ranjit and a few of the other guys from down Sydney way use these models to do daredevil acts such as who can land quickest when the wingman gives the command ‘land’. Inevitably there are midairs and ground collisions, but the Skyraiders come through it with little or no damage. That said the do try crazier stuff like combat with streamers and upside down fin scrapes which has lead to one of them (who shall remain nameless) having gone through six Skyraiders.

As an aside Ranjit is the currently holds 3rd placed world champion for F3D pylon racing. He is sponsored by JR Radios, and that is the latest and greatest JR 12X 2.4 GHz radio he is holding. The receiver in the Skyraider has one main and three satellite RXs. The 12X radio has a download system which gives a readout of each RX’s performance during any flight. The 12X system also has a program that installs on a laptop or PC which enables the user to set, alter and upload and download parameters between the radio and computer.

Ranjit also cooks a damn fine chicken curry for Sunday evening supper over a campstove.

Jeremy Randle with an electric powered twin Moskito. This photo is of a model was built, but never flown, by Jeremey’s workmate, friend, long time aeromodeller and motorcyclist Allan Trinder, who passed away earlier this year.

It is from an English model magazine plan which featured both the British Mosquito and the German Moskito. The workmanship on the model is excellent, as is the performance. The model has 380 brushed motors, Schultz speed controllers and a three cell lipo pack.

Notice that Jeremy has colour co-ordinated his apparel to match the model’s camouflage.

Last photo is of me (Andy) after having flown the Trout in the dark. A low pullout from a loop caused the undercarriage to retract. This was a mighty sight for the spectators as the flight was over tarmac and the resultant trail of sparks was phenomenal.

Lithgow floatplane day 2009 (Andy)

Once again some of the Cowra boys made the pilgrimage to the Lithgow MAC ‘Float Fly’ at Lake Lyall (see last years report in archives) Andrew and Ian on the Saturday, and Andy on the Sunday.

There was a good crowd, including the regulars at this event, even though the weather was blustery and cool. The wind was off shore which meant landing toward yourself and well out in the lake so you didn’t spear a fellow Floater with your model. Take off though for safety reasons meant taking off with the wind up the tail of the model. A good deal of power was required for this manoeuvre. A number of models failed the test in this regard, and never got off the water. They worked like a good speedboat.

The images below is of a very nice Hanger Nine Ultra Stick on a set of Dave Brown laser cut floats. It is powered by an Enya 120 four stroke. This particular model is very well set up and lifts off the water and comes back on beautifully and with no fuss. It also flies nicely in the air. Probably the best operating model on the lake.

The images below are of John D. from Orange’s model. It is fitted with a set of the ubiquitous foam cut floats purveyed by Col Taylor and his friend Daryl Reilly. John’s floats have a trick to help them break the sticktion of the water. They actually have a paddlepop stick fixed at an angle at the step as you will see in the photo. This modification is touted to form a bubble just ahead of the step which allows the float to break from the water easily. Whatever the theory, in practice it works very well. John’s model pops onto the step, skitters along and breaks from the surface in next to no time.

This is Ian Cole’s well travelled Precedent Fun Fly on floats.

The model made two trips to Lake Lyall this year. On Saturday with Ian, and again on Sunday with Andy. On both days is performed well clocking up a large number of flights in the difficult conditions. It got flipped by gusts on a couple of occasions, but suffered no damage as it was in taxiing mode on both occasions. The Precedent Fun Fly makes a great float plane. Daryl Reilly has one (see last year’s report in the archive) so if you can find one or have a kit on hand, you know what to do with it.

Cowra Fun-Fly Day, October 2008 (Ian)

The weather was perfect. The food was scrumptious. The prizes were terrific. The Flying was Fun, that’s what it’s all about. And all that was topped off with the usual Cowra MAC hospitality that makes a great event.

If you didn’t get there you missed out........................But don’t worry.......................It’s on again next year.

Fun-Flys used to be all the rage at one time. They were hugely popular - A mix of friendly low-key competition and social get to gether at a different field. The events were simple, but taught you how to fly your aircraft more accurately and really allowed you to find out how to get the most from your particular setup.

Three events were scheduled for the Cowra Fun-Fly Day, with a bit of informal flying and maybe a streamer cut later on in the afternoon. The planned start time of nine thirty had to be put back a bit due to daylight saving meaning most folk had just arrived at that time. Anyway after a quick pilot’s briefing things got underway.

John's OT 'Funfly' model Looped amazingly well!

Each pilot got to have three attempts at each task, with the score averaged at the end. All scores were handicapped in relation to pilot skill level to even-up the field a bit.

The first task was most loops in 60 seconds. This isn’t so easy unless the model is trimmed correctly. After the 30 second mark the model may be getting off line or drifting in the wind. It takes pilot skill to correct with rudder and aileron whilst still looping tight. Proximity of the ground was also an issue for some. Stuart Barber also found that the Hitech O5M rx isn’t long range like they tell you it is. Winner at this task was John D from Orange Club with an average of 29.2 loops. Interestingly John’s model was an oldtimer.

Task two was to do a spot landing. Now this event tests them out as it has to be set up with a good landing circuit. Also the model needs to be sturdy to allow it to dropped in hard if you overshoot a bit. Owen Luckett from Cowra won this with and average distance from the spot of 2.73 meters. Owen used Mike Ley’s World Models Skyraider which he liked so much he bought it from Mike.

The last task was a timed glide with a 30sec motor run and landing back on the strip. This was won by Neil McQuade from Lithgow Club with an average glide time of 7min 50sec. This was an interesting result as Neil only completed one of the three flights to achieve this average. Neil’s model was an electric glider and the one flight was 19m 32s. It wasn’t much good for loops or spot landings, but sure was good at timed glide.

The range of models flown on the day, and their performance was interesting. Back in the 80’s there was a specific breed of models for Fun Fly events. Light, thick wing section, boom fuselage, huge control surface with big deflection and a 32 size donk. The modern 3D glow and electric models are similar in specification. Unfortunately none of these were at the event. It would be interesting to see how they perform.

Some of the boys get serious While others are more relaxed Mike's Kadet 'Funfly' machine

The event was well supported by a number of the clubs from around the Central West. There were fourteen participants and a few more who came along for the chin wag.

I don't know why, because he has far too many models already, but Mike Leys won the raffle prize, a Dave Brown 80% Astro Hog short-kit. Nice model. The pilots draw went off well too and rounded out the day nicely! Its good to go away with something at the end of the day isn't it?

The flying went on well after the presentation at 4pm. The last to leave were the Lithgow team. The sun had gone and those boys were headed for dinner in Canowindra before going home.

Overall it was another great day for aeromodelling with lots of informal flying of all sorts of aircraft, heaps of catching-up with old friends, sharing of ideas, good food - few flies. After the success of this event everyone was keen to come again next year.Thanks to everyone who came and to sponsors Roj's Hobbies and Dave Brown who helped put the 'icing on the cake' with their useful range modelling products .

To all the club members who put the extra effort in to help run the event – well done, great work. In particular Dave Price the Chef, Andrew Carpenter event organiser and Andy Luckett who is always there behind the scenes.


July 2008 News:Ian

Not much flying activity this month as its been raining and miserable most Sundays. No complaints,its been too dry for too long and at least there is the promise of a grassy strip come spring. Non-the-less the hardier souls still trudged out to the field and had a go in between rain squalls and not-quite gale force winds. Between times we just retreated to the shed for a cuppa and a yarn.

In preparation for Diesel day on the 31st August ( click here for the Oily Hand Diesel Day flier ) w e have been getting our CL models going. Owen and Andy have been flying a low-cost trainer design of Andy's called a 'Trout' (if you give him a ring he will probably send you a plan) and a couple of Dick Sarpolus' 'Little Brother' designs. Somehow this got re-named the 'flying condom' for some reason. We can't remember who fir ed it that but it seems to have stuck. These light basic Cox 051 powered models cost peanuts but go really well once you get the engine going. Once he had warmed up a bit Owen was doing inverted circuits, loops and figure eights with ease. For a bit of nostalgia Wayne H and I even managed a couple of loops on the Andy's 'Trout'design. It was named by some kids in a model building group that Andy once ran. They were also keen on a bit of fishing too! Other CL models on the go in the club include a re-covered Aeroflyte 'Typhoon', a foam wing 'Blaze' from an old aeromodeller magazine and of course the Aeroflyte 'Spitfires' we've been building.

The Sarpolus 'Little Brother' design' Aeroflyte 'Typhoon' minus tail thanks to me! Andy's 'Trout' design .



There has also been a bit of building free-flight going on. Andrew C has a built a Boddington 'Mills bomb' and has another Boddington 'Tipo' on the go both for small diesel engines. I also started few new models in a bit of a frenzy one rainy day and now have two Stiegler 'Ebeneezers', a Smeed 'Tomboy', a Peter Rake 'Sopwith Pup' and a Boddington 32" SE5 in various stages of completion. It will probably take me a while to get them finished however and they won't all make it by the 31st. Most of these were from free magazine plans, does anyone else ever build from these free plans any more? Most of these designs are really good and perform well. The 049 powered free flight 'Tipo' has been built by two teenager tyros that I know and both flew well with only a minimum amount of trimming. They were both cheap to build and fun to fly. What more do you want. Hopefully Andrew's will perform as well. Roll on Spring!

Lithgow Floatplanes 2007 (Andy)

Saturday 24th and the weekend of the long awaited Lithgow Float Fly had arrived. After a bit of jiggery pokey we had fitted all the models and our camping gear into the Hilux and trailer. Ian and I made the 150km drive and arrived at Walarawang in time to miss lunch. Luckily we had emergency supplies. After lunch and a hello to Browny, Whitey and the inimitable Phil Poole from Gosford we checked out the site.

Lake Wallace is an excellent flying site with picturesque surroundings, including the eerie light show of the power station smoke stacks at night. The spot where the models are flown from is easy to access and the water shallow enough to retrieve models if they don't go where they should (like the Viper). After having observed the antics of the pilots already flying we excitedly got out our projects of the last four friday nights. Ian had a pink 'Fun Fly' on foamies, a trainer on 'Pilot' floats, a 'Tomboy' on pontoons and I had a 'Viper' (which placed second at the last round of NSW pylon champs two weeks previously) on a twenty years old set of 'Pilot' floats.

The variety of other people's models was astounding. All the way from Dave Brown’s ‘two blokes have to carry it’ Anderson Kingfisher to little electric do-hickeys on floats. The variety of pilots was about the same. They were moving around to much to count them, but there must have been forty and twice that many aircraft. So we found ourselves a clear spot in the pit area and got into the flying. We had a lovely afternoon honing our skills getting off and on the water. Mostly the models worked well. It was the pilots who were the problem. I ended up with the Viper upside down half way across the lake after taxiing too far and getting caught on a wave on take off ripping the tail off and soaking the model.

Later,when it got calmer Ian got the Tomboy out. As ususal the AM10 diesel fired easily on my fine fuel brew. It really didn’t really need the floats to take off, it just jumped off the water. The landings were ok when the glide speed was kept up otherwise they were more of a splash. For one flight I backed the compression way off to reduce power and the model struggled across the water for about fifty meters before it became airborne to the cheers of everyone around.

As the afternoon faded we set up camp. A poly tarp was strung between truck and trailer. We thought it had 'flair' but Phil. Poole asked us had we forgotten our sheets of iron. we were snug as bugs anyway. As dusk fell we finished our Coopers and smoked salmon followed by cold meat salad dinner. It was dark by now and we were just about to settle down when green, red, blue and yellow LEDs on something with wings plus another 3D machine with cylumes on it zoomed over our heads. The boys were certainly putting on a night flying display. Zooming round the trees, looping, tailsliding, hovering and all sorts of gyrations.

Sunday morning 6.30am and we were greeted with the whistle of a brushless outrunner. The electric floatplane boys were up aleady to exploit the calm of the early morning.A cup of tea and we had a job to do. The Viper had dried out enough to zap its tail back on then back to the water for another day of fun.
The rescue boats were kept busy both days. The rescue boat is really important as a simple problem like an engine quitting means you have a model in deep water. Ian found this out when the Bobcat had a float rip off on a fast taxi and it started to sink.

Anxious not to make Saturdays mistake we were first in line for lunch of steak sandwich with all the trimmings. Soon afterwards though the stormclouds built so we packed up. It was a wise decision, down came the rain and we headed home.

A big thankyou to Lithgow Club and the members. It is a big effort, but an equally big event. And you know what? It’s all on again 12th & 13th January next year.

A Monday Fly (Andy)

I slipped the Hilux in home at 10.30pm Sunday night after having nailed third place at the Pittown Pylon Event. Monday morning the phone rings. Some guy visiting town from Melbourne has been checking the website and would like to go fly at ‘Milroy Field’. Wooo! I should be doing jobs after being gone all weekend flying. But it is a perfect day and the forecast is for big wind the rest of the week. I ring back and say meet at the field in an hour. Dust of the electric glider and off I go. Buzzing down the road and what’s that dirty cloud of black smoke and the sign ‘slow vehicle 10kph’. Oh! It’s ‘Sooty’ the traction engine and his entourage. Well I’ve never seen one of them on the road before. Been at the field 15 minutes and Graham Jenner and his family arrive. Graham pulls out his glider. An electric version of Thornburg’s ‘Bird of Time’. What a beautiful model. Graham and his dad built it from the plan. But what they did was make a plug of the fuse and moulded it from fibreglass, rather than do the built up balsa. And an excellent job they made of it too. It has a can 600, MP Jet planetary gearbox and 1700mah nicads. And of course it flies beautifully. We put in quite a few flights and caught a few thermals. Got a half hour flight in. Then it was three o’clock. No wonder I’m hungry. Bye Bye Jenners. Thanks for the great day. See you next time your in Cowra.

Phoenix Rainbow:A review by Mike L.

I had been looking at this pretty little electric high wing kit from Phoneix for about 18 months. The box says it should weigh 1500 to 1600gm and has a wingspan of 1600 mm (63 inches). An AXI 2814/10 or a 600-600 can motor with gearbox is recommended along with 4 channel radio and a 12 x 4.7 prop.

It is all wood construction and requires only minimal building. Just fit the tail feathers, fit the radio gear and bolt in your motor of choice. It also comes with a neat fibreglass cowl and a choice of engine mounting methods. It is very easy and quick to assemble. I think it took me about two evenings plus a bit.

The only suitable motor available here in Dubbo was an E-Flite 25. This is an electric motor which is supposed to have about the same power as a 25 two stroke. It can handle props up to 14x6 and needs a speed controller rated at 35 Amperes continuous. I am using an 11 x 7E APC at the moment as it is the only suitable prop I have been able to get. A Venom 35 Amp controller is doing the speed controlling and an 11.1 Volt, three cell, 2200mAh 25C battery is providing the power (Max continuous 55 Amperes). This battery can be charged at 2.2 Amps and judging on yesterday's flight, has plenty of power for this model for a flight of about 10 minutes.

My readings on the internet told me that the Rainbow will fly with a 10 sized engine, is quite nice on a 15 and a 25 is more than enough and my experiences to date would seem to verify this.

However I did prang it on its first flight. I didn't put the aerial up!! !!!!! She flew magnificently for about 150 metres then pitched violently up and then down and BANG. Fortunately the Venom speed controller automatically zeros the throttle if the radio looses signal and so she nosed in under no power. The only damage was to the canopy which has now been replaced with a new frame and acetate. I have left the top open and it acts as an air vent and does not seem to affect flying. Everything was nice and cool on landing.I like it so much I may just lash out on another one some day.

All the electric bits added up to about $250 which is about $100 more than the airframe for an all up cost of about $400. (I already had some standard servos and other radio gear,)

So why would you spend this much on a plane like this? Well for a start it is rather pretty and different from the run of the mill high wing offerings. Then it does fly really well - even in the wind - and does not get gunky. But my main reason was to try out some modern electric technology and to give me a model that can be ready at a moment's notice. It also fits into the car in one piece. So far I am very impressed. Next might be a SE5a from Great Planes using the same electric bits. Or a Fokker DVII.



Harry Rides Again by Andy Luckett

Recently Brendan Ward rejoined CMAC. Brendan had been a junior member and learned to fly with CMAC in his early teens. He is now 19 and a mechanic at a local business in town. Brendan turned up at the field on Sunday afternoon with his model which he had described as some ratty old trainer on the phone.

I was astonished to see that it was HARRY. Harry is a model that I built around 1982. He is actually an Aeroflyte Hustler with different wingtips. Harry did duties with me for a number of years, helping me get my Gold Wings and Instructors rating along the way. He started life in a blue livery with an OS 25 FSR for power. He later had a refurbish and was fitted with an OS 40 four cycle and finished in silver and red. His wing is still red with silver 'Harry' lettering just as it was all those years ago.

Over time he got gradually heavier as he was repaired. He was handed over to Peter Sharp who campaigned him for a while, and then was passed on to Brendan’s Dad, Ian. Ian flew him a bit then shelved him. Harry was a particularly good choice for Brendan to start flying again. Firstly he has gotten himself very tatty, and with an old LA 46 it wouldn’t matter too much if he crashed. Secondly he still has that old Hustler magic. Brendan asked me to do the trim flight for him, and it was with a tear in my eye I accepted the offer.

How surprised was I? Harry flew like the inimitable gentleman he always was. He hadn’t forgotten what it was to be a well mannered aeroplane. He was stable and precise and went where he was pointed. After flying him Brendan commented to me what a nice aeroplane he was to fly. I don’t know if Harry thought Brendan was nice after he had put him through his paces. Loops, rolls, pylon turns, split esses – “whoo watch my arthritic old joints Brendan, and are those rubber bands new?” Ian Cole has suggested we should build another Hustler and compare it to a modern ARF trainer to see which flies better. I still have the plan and an aileron wing kit for the Hustler in the loft. It is tempting. But what would Harry think?

Millenium Cup 2M glider (15th-16th Sepember):Wayne Symons

Cowra Model Aircraft Club held its annual Millennium Cup 2 Metre Gliding event over two days during September. The event was a huge success drawing competitors from many parts of the state. The Millennium Cup was hosted at ‘Yaralla” Dairy and sponsored by Mulyan Wines. A huge thanks to Yaralla Dairy partnership for the use of their paddock to host the event and Mulyan Wines for their generous sponsorship.
There were a total of 23 pilots flying in the 2 metre class event. First place went to Tom Prosser from Nowra, second place to Collin Woodward from Sydney and third place to Owen Pearcey from Woolongong. The Juniors section was won by David Symons from Cowra with a close second place by Troy Zivkov from Sydney.
The weather on the first day provided us with cloudless skies and a very light breeze providing a highly competitive day of flying. The ideal flying conditions concluding in six rounds held for the day.
The second day started off as a carbon copy of Day 1 with only some wispy thin high cloud and very light wind. After a couple of rounds a line reversal was required as midday approached the wind began to pick up. After midday the wind became strong and penetrating up-wind with gliders was a challenge. There were huge patches of lift that took quite a few minutes to move through. Pilots who were fortunate enough to launch at these times were able to work up to great height (in excess of 1000 feet) and getting down on time became a challenge. We were again able to complete six rounds on Day 2 by early afternoon concluding a twelve round competition.
Thanks must also go to the 22 competitors who travelled to Cowra again and participated wholeheartedly in the event which while friendly was also very competitive. As always it was great to both catch up with people who came last year as well as meet some new faces. See you all next year and best wishes for the rest of the competition.

SO WHAT DID YOU DO ON FATHER’S DAY??...Andy's Report (2nd September)

Off to Dubbo we went for the Father’s Day Fun Fly. My son Owen accompanied me as his Father’s Day treat to me. This was a nice gesture on his part as it is not often these days he can fit in a days flying with his dad in his busy schedule. Andrew Carpenter made the trip also and stayed overnight with his good friends Mike and Christine Leys.

The weather was perfect for flying, sunny and light breezes. The Dubbo field is not too far out of town, on the edge of an ironbark scrub. It is a great strip to fly from with the surrounds well placed allowing pilots to easily find their reference points. The pits at the field are fantastic. They are carpeted. You feel like you are in the lounge room. Carpo even nodded of in his chair after lunch.

We took up the Fourstar 60 and the electric glider. We also had a couple of our 049 c/l models. These didn’t get much of a go as we had virtually destroyed them the evening before at our mate Marky’s farm, seeing who could do the craziest stunts. Owen spent a flight putting Mike Leys’ Kadet Senior through its paces. Mike loves watching Owen trying to turn the Kadet inside out. They even discovered it can do knife edge, albeit in a descending path. Then Mike let him fly his ME 163 electric foamie. This was much more Owen’s style of model, with the roll rate of a spinning top. Andrew flew his Scanner and shot the breeze with the Dubbo boys.

There was a good turn up at the event. Lots of Dubbo boys there. A good percentage of them are into streamer cutting. A great spectacle. Find the link to their website on this site to see some photos in their gallery. Toward the end of the day there was a pilot’s draw. I got a pair of wheels that will go on the Adrenaline. Then the raffle for the Miss Dragon 60 was drawn.Who won it? Carpo. Well you could barely believe the whooping and ki-yi-yippie-yi-yaying that came out of that boy.

But that wasn’t the end of it. No way. He couldn’t resist the opportunity to wheel and deal, and soon had traded the kit for a motor after having drummed up and turned down three previous deals.He’s still has a grin from ear to ear. The sun was sinking as I farewelled the Dubbo Club and pointed the Hilux for home. What a great day.

22nd July 2007

A beautiful calm sunny morning after a hard frost yields the most pleasant flying conditions. And so it was for our visit to Wombat Field on Saturday 21st July. We made our way in a leisurely fashion to Wombat leaving Cowra about 10:30 and morning tea-ing at Dates Café at Crowther.

We arrived at Wombat to be greeted by the King of Modelling in Wombat, none other than the 'builder many of Cubs', Col Wilson. Col Ashley was also across from Coota. You know that all Wombat flyers are called Col. That is one of the rules. So we changed our names to Col for the day.

Wombat Field is on the only bit of flat ground in the district. Perched on a little plateau that drops off sharply to the south and west and rises to the east and north. At first this appears a little daunting but it’s just like going in the cold water for the first time. Once you’ve done your first flight its plain sailing (flying) from then on.

We flew R/C for a bit and stopped to BBQ our lunch and have a cuppa. Then Col (Andy) and Col (Col) indulged their passion for control line. Round and round they went all afternoon.Col has a lovely little Cessna powered by a Taipan 2.5, all ready for Diesel Day. As usual Andy’s ancient ‘Trout’ Cox powered trainer needed and engine transplant. Andy also cranked up his Hearne’s ‘Demon’ with the old Fox 29 in it. A few circuits with Col’s ‘Bipe’ and the dew was starting to form on wings so it was pack up time

Back into Col’s place to browse through his vast collection of models and view his old Honda Benely, and it was home time. I forgot to buy some of the Wombat Eggs advertised at the roadside stall, so I guess we’ll need to have another flying day on the hill.

15th July 2007

Not a great deal of activity this month so far. The promised trip to Wombat field was postponed due to rain which made access to the field impossible, still can't complain as the rain is very welcome. Otherwise, flying conditions have been cool and calm. Ian even managed to get his Tiger Moth out for a bit of a fly around and photo-shoot for an upcoming talk to a local community group.

Sunday the 15th was another milestone (I think) as the first twin engined aircraft took to the sky from a club field. The aircraft was an 'Executive twin" built from airborne plans by Col Wilson. In fact Col liked them so much he built two, but the person he built them for changed his mind about the project and so Ian and mike picked them up for the right price from Col at the last 'Oily Hand Diesel day (next event is on Aug 4-5th).

Although not properly run in yet (they're ringed engines) they were running so consistently that a few, and it took to the sky. A bit of nose down trim and everything was fine. A couple of figure eights and circuits and it was time to land as it was getting late. She came in fast and the landing was a bit rough but both motors were still going allowing a dignified taxi back to the pits. A very sucessful first flight.

It was great to see and hear a twin in the air for a change. The Executive Twin seems a very practical first model although the fourstrokes probably raise the wing loading a fair bit over the 15-25 size two strokes it is designed for. Landings are probably going to be fast as a consequence but the model handles sweetly enough and I guess it will be less affected by wind. The sound of twin fourstoke motors in close harmony is certainly very nice.It remains to be seen what the one engined performance is like.

June 2007

16th and 17th June saw us hosting a round of the MAS Pattern Aerobatics competition again. Sunday was very windy and only two rounds of 'masters' level was flown before the CD called it a day. Saturday saw a much more pleasant day allowing all levels to fly 4 rounds finishing about 15:00hrs.

Club members who contributed to the day were; marking out the field and cleaning up facilities on the friday (Andy and Andrew), pencilling scores for judges (Phil, Richard, Andrew, Ian and Andy), keeping the billy boiling, cooking and serving up the 50 home made gourmet rissole burgers and 'cup of soups' Andy had made forlunch (Andy, Ian, Andrew) and actually flying in the comp. (Andy). Thanks to all concerned it was a great effort.

After the 'medals' had been handed out and the official part of the day was over several members proceded to get models out of cars and go for a fly. Collin brought over another cub to fly (how many cubs have you built in total Col?) and Dave took his big cub for a fly again. Dave must get a medal for persverance as we have yet to sort out why he suffers so many motor cuts with his current set up and every flight ends in a dead stick landing. Andy was also keen to pratice his stall turns in preparation for the next comp at Gunnedah next month.

The club would like to thank Grace and Tony Law for organising the Cowra round of the comp., CD Tom Prosser for running the days events so smoothly despite the weather and all the competitors who really made the event work out so well.We hope you all enjoyed your time in Cowra.We hope you come back next year.

27 May 2007


The need to get rid of some fallen timber from around the pits area meant we were forced to have a bonfire and BBQ......it is a tough life. Everyone who came enjoyed a perfect winter's afternoons flying, food and social although by 4:30pm the shaddows were starting to move over the field and it was time to put the jumpers on. The following couple of photos of Club president Andy say it all really!

28-29 April 2007

After about 5 very pleasant years flying off Carl Siegert's property 'Ferndale', Carl regretfully informed us he was going to retire into town and sell the property. Unfortunately we were unable to negotiate with the new owners so we had to relocate at short notice. A considerable amount of effort was put into trying to locate a new field to no avail until Matt Robson (a club member) suggested we fly from his property. We moved on the 28-29th April. It was an all hands on deck affair that went quite smoothly all considered. The biggest job seemed to be getting the shade shelter legs all lined up and level to Andy's satisfaction.

We owe a debt of gratitude to Carl who has kindly looked after us all these years, maintaining electric fences, leveling and re-seeding the stip and filling the water tank from time to time. Many thanks Carl, we wish you well in retirement, perhaps you will now have some time to fly again!

Thanks also to Matt who will now have to put up with a lot of crazy modellers on his property every flying day.

A new cleaning tub for small model engines: Ian

Cleaning small engines usually means their disassembly and soaking in solvent (usually petrol because its cheap) to remove oil, dirt and castor gums.To date, like most people I have usually used a small glass container or an ice cream container so that I can put a lid on things to stop the solvent evaporating away. The trouble with this system is that the small parts get mixed up with the sludge and dirt at the bottom of the jar and can't be seen. When you toss the petrol out these small irreplaceable items go too. To get around this problem I usually strain the cleaned parts from the solvent through a rag, but this is not ideal either as the parts are still mixed up with the grit, paint and sludge and need to be cleaned with another rag before use.

But I have now come upon a fantastic new container for cleaning these parts. It is thinners and petrol proof, has a built in strainer basket that holds the parts to be cleaned away from the grit and sludge. This basket can also be secured in a raised position above the solvent to allow the parts to drain. It also has a lid to keep the fumes in.

The only down side is you have to buy the olives that come with it....but they are grown in Australia so you will be supporting a local industry anyway. (Better still, slip it with your grocery shopping and it won't cost you any of your hard earned modelling dollars at all!)

A winters day at the field (June 2008: Ian)

A big high over the state and no rain predicted. All looked good (unfortunately because we need quite a bit more rain). Even though a breeeze sprang up at 13:00hrs it was a great day for flying. All the regulars were there.... plus a few. Col had once again made the pilgrimage from Wombat to test fly the latest of a long long line of Piper Cubs and Brendan turned up with a friend to put a 20+ year old Ugly Stick through its paces. Richard also came out to give his new HiTec radio setup a go in his SID Kadet Snr, another very-nice-to-fly aeroplane in the classic mold.

Andrew test flew his semi-scale 1930s racer (similar to a Corben Super Ace) that he had resurected from a 'freebee'. After quite a bit of work it has come up nicely and was perfectly matched to the OS40FS in it. Even Dave had his Bird Dog sorted. After endless trouble with engine cuts, fitting an onboard glow driver has solved all problems and the model now flies like its on rails. I had high hopes for my 1/4 scale cub. The engine has given lots of trouble over several years as a result of dodgy carburetors. I thought I had the problem solved but apparently not as it refused to keep running despite some desperate fiddling. I am finally giving up and taking Andy's advice and re-engining the model with a Saito 125s.

After helping Richard with the Kadet Senior, Andy even had time for a flight with an electric glider.

All-in- all not a bad winters day.

Airborne Executive Twin #2 (Ian's 'blogg')

Twins seem the latest fashion in the aeromodelling market these days. Check out the number of twin ARFs around. Must be the low priced 'brand name' engines you can get these days. Anyway I had been saving up 2 engines of various types for many years and as a result have 2 of almost everything from PAW 2.5 diesels , OS 10 FSRs, OS 40 FS,Enya 52FS, Magnum 46s, ASP30FS and OS 25FPs. But for a variety of reasons the project always kept on being put off. I.Two years ago the opportunity came up to buy a already constructed Executive Twin' from club member Col Wilson. The ARFs are very nice but I didn't fancy trying to fix them after the inevitable bingle. I wanted something I wasn't afraid to crash and that would be fixable when the inevitable happened.

I had a lot of fun with the plane and learn't a lot. With me, its one thing to read about how to do it but its only when I have had a go myself that I really understand it. I had lots of flights...lots of engine cuts that I had to deal....and only two overnight repairs to do over an 18 month period (nosegear former came loose and wing bolt bracket came off as the result of out-landings in rough terain.

The last flight inevitably came, just as I was getting (too) confident in my own abilities. An engine quit on takeoff...I was a bit slow to notice and before I could decide what to do the plane decided for me...dropped a wing and I didn't have the height to recover. It hit some steel sheep yards and exploded in a shower of balsa fragments. Mike consoled me with the thoughtful words 'At least it had the decency to smash itself well enough to put it beyond repair'. Thanks Mike! Anyway another lesson learnt, but now hooked I was in the market for another twin.

It eventuated that the sister ship to the first model, also built by Wombat's Col Wilson was close at hand. It had had several owners by now but no-one had actually flown it. So I bought it. Andrew offered to help me get it going again but this time we have fitted it out with OS25FPs instead - just to see how 2 strokes go for a change. I also thought that the lighter engines might get around the need to mount the batteries in the tail but this wasn't the case. I think you would need OS15s before the model would balance with the batteries up front. Also as an experiment we added 2 degrees out-thrust as some magazine articles suggest this helps counteract the yaw that results when one engine quits before the other.

How does it fly? Will keep you posted.

Update on Andrew's Super 60 (Ian)

Our write-up of Andrews 'new' Super 60 (see 'Early May at the strip' below) brought the following reminiscence from Bob Allan

G'day all in Cowra ! Was interested to see my old Keil Kraft Super 60 pictured on your website. The frame was actually built by a cousin of mine (Terry Allan ) who then lost interest in the project, so I finished it off, covering it with Solartex and fitted the Futaba "Gold" 4 channel radio.

It was originally fitted with a gold head Taipan 3.5, but along the way, it was also fitted with an OS 35 and the aforementioned big PAW Diesel (the less said about that, the better!). Sending a photo taken on the farm at Watta of my eldest son (who is now 31!!) holding the pristine '60' fitted with the OS (photo taken 31st May 1986). As mentioned in your writeup I still collect model engines, and you can ID me on eBay as 7enya7 or n***7 on the bidding list. If you frequent the various Forums to be found on the net, you can ID me as Starlight7 on Stuka Stunt Forum, 7enya7 on Barton Forum and 74SEVEN7 on RC Universe.

In case you're wondering what's with all the "7's", well my son photographed with the Super Sixty (below) was born 7-4-77. The Enya bit refers to my love of Enya engines, and if you want to read some short articles I wrote, type Supercool Racing Propellers into Google, and click onto Articles. Keep 'em flying boys! Regards, BOB ALLAN.

Spitfire project progress (Andy)

The Aeroflyte C/L Spitfire project is progressing well, although none of us made the Easter deadline to fly at SAMS Canowindra. Owen is close to the finish line. Some more sanding and dope and a lick of paint and he will be done. The rest of us are spread across the field. At this stage Ian is running a very poor last and Carpo is coming up fast on the outside rail. Phil is the dark horse in the pack, his wing is turning out very nicely and the fuse is shaping up.

There are two hang ups to getting the models complete; The first is a lack of suitable canopy. We are going to have a go at vacuum molding. Ian has already had a go and has supplied a vacuum molding box. If we can get this technology working it will be well worthwhile for the scale modellers in the club. The second issue is the cowling.No decision has been made at this stage as to whether we do a fibreglass one or just cobble it up from balsa.

A variety of engines will be fitted.Andrew has a brand new OS 15. brendan will use a trusty Magnum 15. Owen has purloined one of Dad's OS 20s, whilst Dad will fit the same Taipan 2.5 diesel as in his original Spitfire back in 1967. Phil has access to an OS 15 and Ian has an Enya 15. Thats half a dozen spitfires when they are all done. Thats about one wing of a flight out of Biggin Hill, 1937.

Early May at the Strip (Andy)

Gokies it’s dry at the field these days.

Last weekend of April there was no flying as Sunday bought a raging dust storm with visibility down to 50m. This week it was dead calm, but have a look at the photos. How dry and barren is it at our strip. Still it was the most beautiful afternoon so we flew.

Andrew Carpenter had his ressurected Keil Kraft Super 60, the 60 being 60” wingspan. This model has a history. It was originally built by Mr Bob Allen back about 1986. Some of you may know Bob as he has always traded model engines, worldwide! In Bob’s ownership the model was red and yellow and powered by a PAW 35 R/C. It later passed into the hands of a young Ewin Dun who powered it with an OS Max30. Somewhere between Ewin and the next time it surfaced it was crashed and ended up in the possession of Ian Trethewey. That’s where Andrew came into possession of it in a job lot from Ian. Andrew rebuilt the fuse, covered it red and black and clomped an OS 40FS in it. Flys like a dream. The KK Super 60 was a very well designed aircraft. Andrew also had his very nice brand new 80% Astro Hog built from a Dave Brown laser cut short kit. The model didn’t get it’s maiden flight as it had an odd vibration that Andrew wanted to investigate back in the workshop.

Ian Cole had fitted out a Corby Starlet with an ASP 80FS. Surpringly enough this particular ASP runs ok and doesn’t cut out in the air on any old whim. Ian also had his new MP Jet .5cc diesel which we ran for the first time in preparation for Diesel Day on 30th & 31st August this year. This little motor runs like the much touted sewing machine.

Aeroflyte Spitfire project (Ian)


In an attempt to experience the joys of youth Andy has convinced about 6 of us to build the venerable Aeroflyte spitfire control liner. It's a bit of a change for those who have only experienced R/C models and so there is quite a bit to learn about the fine detail of how to put a C/Ler together despite their apparent simplicity.

With the benefit of experience and the resources and wisdom that comes with age quite a few refinements are finding their way into the models. Owen has gone for a more scale like look with a revised under carriage position and raised rear fuselage.

Anyway most models are making good progress and some should be finished sooner rather than later.

New club projects for 2008 (Ian)

Late last year following something I read in RCM News about a group who were flying RC Combat at Werribbee, I made contact with Jim Bonello to find out more about it. Jim was very helpful and sent down a foam core/short kit for me to assemble. It has been completed for a while now but it took me a while to find a good day to test fly it. The test flights went well and it flys like it's on rails. It's nippy little thing, and you certainly need to keep your eyes on it 100% of the time.The CG needs some fine tuning as when the engine stops it comes down steep and fast and is impossible to flare and land smoothly. Every landing except one ended in a dull 'thud' and a cloud of dust.

The exception was when I decided to land on the long grass. Not a good idea! One wing clipped a tall tuft resulting in a spectacular high rotation speed cartwheel (more like a frisbee really) for about 20-30 metres. Still, the only damage was a bit of foam crush at the wing tip leading edges and we were flying after a quick refuel. Mylar covered foam is really tough though it doesn't look pretty!

So it shows promise. So what about it? Anyone keen to come dogfighting with a cheap 20 size model?

In the mean time it was decided at the last meeting that there are about 6 of us going to put some Aeroflyte (Control Line)'Spitfires' together far a bit of a trip down memory lane. We aim to have them going by Easter (2008) for the SAMs event so if you want to give CL a bit of a go again see Andy for the details. They take a 15-20 size glow motor and should go together in a friday night or two.
