RE: Bizarre plane behavior
Cutaway, sounds like you have "been there done that".
Yes the further forward I move the CG the more control I have. I started just on the leading edge of the main spar and that was unflyable. Plus I compounded the problems by mounting the motor with too much down attitude and I had the throws set quite aggressively to start. When I painted it red and black, I had no idea it would turn out to be the Devil Plane.
