I thought of something. If I add quite a bit of ballast and add more support to the rudder/elevator assembly, won't the motor start becoming insufficient for pulling the Radian up on a steep angle? I'm very experienced with planes yet, but I do know that a 380 motor fits in a 540 or 550 hole pattern. Is it possible to put a larger motor in it? And then is there a steeper or bigger prop to provide more thrust for the weight of the new motor?
