The Simitar Top Motion tailess rc airplane.is my own variation - Built over 20 years ago, I only fly it every 5 or so years. I have built every version published (over 50!) by its creator and my very good friend Bill Evans (AMA Hall of Famer!).
The Top Motion was created to do some very violent (now call "Extreme") high speed tumbles and flat spins. It has a very large rudder, wide wing chord and reward CG setting), the control throws are also very extreme while in high rates. The video was taken with n Iphone, so its hard to see the "Simitar Tumble" manuever clearly. Its powered by a JR 2.4 DSM and Super Tigre .75 on a Tuned pipe, the prop is a 12/6 APC. At low rates the Top Motion is more docile than most trainers with tails and the model thermals really well when the tank is empty.
The video was taken at the River CIty RC Club flying site at E.P. Tom Sawyer Park
Holy cow! Is that thing fast enough!?
