Some figures on the #3. Span 35 in, chord 8 at fuse, 6 1/2 at tip (fixed flap),wing to nose tip 5 1/4, wing to front of stab 5 1/2, stab span 15 1/2, chord 5 tapering to 4, fuse 3/4 wide, 2 in high. Rudder 3 1/2 high. Such a trainer is easy to build and very sturdy. I'm recovering from some leg problems, and went out Sunday to fly for the first time since early June. Flew my #2 with McCoy 19 on 65 ft lines. Flew three fights and did not crash nor fall down.
