I've got a Magnum 91 FS laying around and was thinking about putting it in this airplane. Any reason not to? I was thinking about propping it with a 15X4 or 6 and moving battery and receiver around along with servos if needed to get correct C.G. I enjoy aerobatics but from what I hear this is a good plane to actually "fly" instead of tractor around with a big motor. Will the Magnum foot the bill?
