Control Line Stunt
Engines .29 - .35
by HI JOHNSON
Our first approach to stunt was the barn-door type which, if well balanced aerodynamically and statically, turned in some beautiful Rights. As we made progress, the stunt pattern was evolved, and each judge and pilot had his interpretation of a good maneuver. Finally the AMA gave us pictures and descriptions which settled all arguments Stunt pilots knuckled down to some real precision flying. This put pressure on the airplane and its powerplant.
Many approaches to scale in stunt ships have been tried. The Stuka has been a favorite of mine, especially since the wing planform places the bulk of the area close to the fuselage, where the moment arm (area moment) is short. This makes it ideal for calm or windy weather, and for slow or fast flying.
The polliwog airfoil, if used on a rectangular planform, is a slow flier but, if used on a fast taper, works beautifully through the full range and is fine for a good stunter without flaps.
