I have been flying my Magic for about a year with the Leo .37 engine. I assembled it using Hitec 225BB mini-servos and used a triple A NiMH battery pack with Hitec 555 Rcvr. It comes in at
3 Lb. 10 Oz. and has truly unlimited vertical. Outside manuevers are so-so and knife-edge is nil, but for pure fun this is a great plane. Notice the engine position which puts the exhaust out between the landing gear. Clean-up after five flights can be done with a single kleenex.
