RE: ESC ratings, what do they mean?
If it were a 15C 1000 batt., then it would be 15 amp, so being 1500 it would be 22 amp draw. Only difference in using the bigger ESCs is the weight goes up as they get to higher amp rating. The motor we were refering to above was a 20 amp motor. The KV rating is the RPMs per volt, so a 1200kv motor would be drawing a certain amps on a certain prop. If you were to go to a 2400 kv of the same motor it would draw double the amps, so you would have to put a much smaller prop on it to get it down to the required 20 amps. Does that make sense??
