- Perhaps you are asking yourself if you will get any practical know ledge about stunt flying from this article. Aside from a discussion of the "Pegasus," I will try to develop a few points which will be beneficial to many beginning stunt fliers as well as some food for thought for fully developed fliers.
Basically, consistent success for me has resulted from, 1) the development
of a practical and efficient design, and 2) a few guidelines of common sense
which saved me from' countless wasted hours and plenty of heartache. Before the completion of the "Pegasus," I built several aircraft trying different aerodynamic theories. I have encountered nearly every problem, gimmick and pitfall known to stunt firers. Some of these will be discussed as we progress.
The "Pegasus" was built around a set of moments and thrust lines which are
widely used. The airplane has a higher ratio wing than most stunters for the following reasons: 1) I wanted more area in order to carry more weight; 2) I wanted a tighter corner; and 3) I wanted to rid myself of what you might call residual lift in the round eights. The last point was more of a problem concerned with the flap area. I had been getting too much lift in the transition between inside and outside rounds which caused a hump right after the transition occurred. Therefore I changed to a 57" wing of 630 sq. in. with 2%" flaps which tapered to %" at the tip. With the narrower flaps and higher aspect ratio wing I gained the area I wanted, got a tighter corner
