Whatever works, I find the opposite to be true. Personally I prefer the prop which gives the best performance without endangering my electronics. Averaging 100 amps with peaks of 120 amps the H-7 does not create any "dangerous" heat after 6 laps in my personal JAE21 in the hot Texas Summer. Laps average in the 12s with top speeds in the upper 70s. I run a Castle 1415/1Y. YMMV.
