To harness all that power we are using the E Flite 40 amp ESC (speed controller). The best thing about an E Flite 40 is that you simply plug the thing in and it works. No fussing or messing around with programming. You just use it. This is especially nice for someone (like me) who doesn't implicitly understand how electrics works. At 40 amps, the ESC is much heavier duty than either the battery or motor, so this is a good safety margin, especially since the radio relies on the ESC for power. I don't care if the motor blows up as long as the radio doesn't go out and causes me to crash in the pits or something equally dangerous. However, this has never happened, or even come close.
