CONTROL LINE STUNT
ENGINE .35
WINGSPAN 54"
By larry Scarinzi
The "Grey Ghost" is a full stunt model designed for the usual purpose, that 'being to give the builder a good looking stunt model that handled well and was still capable of winning contests. We don't claim the ship to be completely new and different in planform and theory, but instead it embodies only proven theories and ideas of stunt model design after getting half way through construction the somewhat big size of the model convinced us to use our hottest Johnson .35 for power. This we 'soon realized was somewhat of a miscalculation in the power department. With a good healthy home brewed fuel the ship hit an even 90 mph in level flight. It's an eye-opening sight to see a huge 54" span stunt model screaming around through maneuvers at speeds greater than many much smaller combat models.
Realizing this was a little fast for practical stunt competition and that the wings were bending perhaps to the point of being dangerous, we resorted to our original planning and installed a Johnson Stunt engine and a much milder fuel. This fuel consisted basically of 27% Castor oil, 10% Nitro Propane and the remainder Methanol. With this combination we were able to throttle our speed between 72-78 mph. This is the way we generally flew it. Streamlining sure pays off.
The model was designed with a lot of reserve turning capability. This was done to conform to A.M.A. stunt rules
