Hi Fernando, I think you are right. The Rotorshape is a good electric trainer. It is important for a trainer autogyro to have a rather long fuselage, that is, the tail surfaces being away from the rotor disc (like the Rotorshape). The trainer you designed might be a good autogyro once the proper adjustments have been made but apparently it hasn´t got a long fuselage.

Good luck,
Emilio
