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.
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.
