But why would it be going over 45A while static testing? Wouldn't this be too much for the ESC? see http://www.youtube.com/watch?v=0fiPL17fISo&feature=plcp I am only assuming it would go over 45A on full throttle but wasn't game to push it that far.
You could go and get a 55A ESC and be safe but the main thing is that you are holding the motor down causing the motor to work harder to suck the air as apposed to if the plane was moving then the air would be going through any way and the only time Amps are a real problem apart from a static test is if you are hanging on the prop and EDF's do draw more amps than other motors in a static test because they rely a lot on the oncoming wind. But I do see your problem and just for safety you could get a higher Amp rating ESC.
