Well then, I'd get a Neu. Since it's gonna be on a truggy, I'd get a 1515. So, it's just a matter of finding the wind. On the higher Q motors, I shoot for between 35k and 40k max rpm. Just take that value and divide by the battery voltage to find the kv. Then, find a motor that closely matches that.
