Hi guys, I have one of these also and love it. I have stock set up also and it flys great. I clocked mine with radar gun at 68 straight on and level. I'd buy another one if I take this one in. So far so good. Very easy launch, I think anyway. This is my favorite edf. This and the firebird. To answer your question about the motor, I can't answer that, I'd go with stock and then maybe try it later. Later........ f-86
