These pages are a running record of my flying activities updated spasmodically.
Very early on (1960's) at the Mildura Technical School sports ovals I flew IC powered control-line balsa planks models carrying house bricks - to see whether it could be done of course! Actually they were half bricks as that was all our puny teenage arms could cope with pulling on the lines.
From memory I started flying again around September 2001.
Check out You Tube for flight videos (gke3800).
In reverse build order.
Ready for Test Flight(s) 23 May 2016
Maiden @ VARMS
20160531 Low & Slow @ VARMS
20160602 EDF V1 @ VARMS
Based on Josef Poisinger's Build. In my case a 1200mm version and foam cored with 8% section. There is an RCGroups Blog.
600mm Indoor Version March 2016
20160420 Indoors @ Waverley
I built a quicky 600mm indoor version using WLToys Polecat electronics and Diaso ColorBoard foam. There is an RCGroups Blog of the build details.
Ready to Fly March 2016.
Fuselage built by Birdy and Roger. Birdy was unhappy with kit balsa but I elected to follow through with original kit adding air brakes and 8x0.5mm carbon straps to the bottom spar and replaced inboard ply shear web plates with 2mm carbon sheet at the wing roots. AUW 1.9Kg.
Maidened 22 March 2016 @ VARMS - thanks Ray. Magnificent!
Muesli October 2014
Medium aspect ratio (1.8M, 250mm) plank looking surprisingly like the P16025 and constructed by Ray Cooper. Not a recent build - more like removing some decals from an old bird.
While Muesli uses the EMX07 airfoil in the future I may try the PW75 which has less drag than the EMX07, an adequate Cl and the same positive pitching moment. The PW75 seems similar to the JWL065 but a little more consistent over a range of REs.
PopCorn January 2016
Successor to Cornflake. Rebuilt fuselage after a radio outage at Kilcunda - antenna pointing at aircraft! There are some VERY rough build notes (zip) after requests from VARMS members.
Only damage so far was a badly split fuselage after being blown head over heels backwards down the field after landing in wind velocities higher than PopCorn's flying speed. Some white glue and fixed!
Phantom with Colin Smith "Kilcunda Notch" (Right Wing) February 2016
Changed motor to Turnigy D3536/6 with 9x6 Aeronaut Folder. Added Birdy preventers (fibre glass plates in hub crossbar) to stop prop crossover when trailing and flicking forward hitting the wing at spinup.
OK on the slopes. Fins are largely decorative as it flies about the same without them. The usual yaw squirms common in some wings!
Fluity @ Home 21 January 20142014
"Fluity" is corflute flying wing design due to Paul Van Tongeren aka Bixler Boy. Build time was about four hours including waiting for paint to dry.
All up weight 550gm. Drive line is a mild ex AXN Cloud Floater
with 7x5 prop and 1000mAH 3S pack. Not a white knuckle rocket but does vertical
happily and covers the sky quickly enough. On the numbers should do a little
over 100KmPH but the airfoil section is WYSIWYG so when drag meets thrust is
anyone's guess. Throws +/-8mm aileron and +/-6mm elevator.
Had a minor oops when when demonstrating at Pauls workshop accidentally launching with maximum rates - several snap rolls right and several snap rolls left at an altitude of about 1-2M then a "controlled impact with terrain" as NASA would say at high speed. Damage was extensive LOL - broken prop or more correctly blades removed and a slightly bent motor mount. Back in the air next day.
Discus launches seem to work and are necessary on still days with about 5% up dialed in. I don't recommend hand launches for pushers BTW - just my choice but but when I do it I do it with my thumb across the throttle holding it off. I now have my Taranis which is programmed to "yell" at me if I don't have low rates selected at least for launch .

20160602 Lancaster @ VARMS
There was no excuse for buying this in 2006! The Lancaster kit was designed by Tony Nijhuis but has a 72" span not Tony's scaled up larger 17' version. Others have had fun building it including a few mixups with the plans.
SLEC produces a part kit with CNC cut formers and ribs.The CNC ribs I received at the time were VERY warped like the Spitfire kit. This was going to mean a lot of fiddling to get things lined up in an acceptable manner.
Recommenced building in 2011. Kit was reasonably complicated and I thought at the time probably more so to fly.
I changed the build sequence a little as I found the nominal sequence to be messy. The fuselage tops do not curve easily even when damped with water and ammonia. I would use planking next time. I have built the centre wing panels as one piece and will cut them apart later. Some templates on the plans for the rib angling for motors would have been useful as it is easy to get it wrong.
Late decision to initially finish as a Manchester to be flown bare balsa which I did 21 October 2013. It is a pussy cat to fly. Hopefully it will not take another seven years to paint.
Finally completed in 2015 as the Lancaster Aries after some sagas with the undercarriage. Still needs decent flair when landing but that's probably as it should be! 4x Turnigy 2213/20 with three blade 8x6 Master Airscrew counter rotating props. 4900mAH 3s pack. 3Kg AUW.
