I agree that I CAN exceed the continuous rating of 42 amps when I hit WOT. But the specs also state that the motor can take BURSTS up to 60 amps not to exceed 15 seconds so as long as I stay at 42 amps or below for continuous use and don't stay above 42 amps for longer than 15 sec bursts and I don't ever go above 60 amps then NO, I HAVE NOT EXCEEDED ANY LIMITS! Now, as to Mustang's comment on needing a larger motor to be happy with this plane, that may be so, I will let everyone know once I get to maiden it. It is way to windy here for the last couple of days. Maybe this weekend I hope!
