Burning up motors
My cajun commander esc burned up. While waiting for the replacement to arrive, I decided to install a different esc and a 12 turn brushed motor. So my son could at leave enjoy it a little. The motor started smoking after about 30 seconds. Can someone explain why?

The 12-turn motor is not designed for 3S and the stock prop. It is a high rpm motor and is trying to turn the prop too fast; since it can't reach its optimum rpm (prop too big) it converts the amps to heat - quickly. Result is a burned up motor and perhaps the ESC. If you want to use the 3S pack you will need to use a motor very close to the stock motor (1800 stock Kv versus about 3300 for the 12-turn and/or use a smaller prop.
