Is this bad?

The heat is from motor braking, essentially the mosfet reverses the current to stop the motor instantly and prevent overspin, you also might have ROF control on, in which case the BTC will brake the motor in between each shot. this makes heat. Braking will wear the motor faster, BUT that said ive been using AB for the past 5 years and i have yet to ruin a motor. As far as the battery, your 15c battery is not good enough if it is getting hot, you need a battery with a higher discharge rate, or more mah. The formula for the discharge of the battery in amps is ((c)*(mah))/1000. Lipos will have to c ratings on them, a burst and a constant rating, the burst rating will be the higher rating and is the maximum amount of current the battery can supply to start the motor, the constant rating is the maximum discharge rate over an extended period of time. A very simplistic way of looking at it, although not entirely correct is to think of it as when you shoot in semi you use the burst rating, in full auto you use the constant rating.
