RE: Not another 4* 40...
Tonight I got all of the tail section framed up. The horizontal stabilizer has a span 1.25" more than stock. The Elevator halves are 3/8" wider. The vertical stabilizer is 3/4" taller than stock. The rudder is 1/2" wider and the hinge line is angled back slightly. Hopefully these increases will make a great flying plane even better and won't make it too touchy. If it is, I guess I'll just have to reduce the throws and/or add a lot of exponential.
