Default RE: which motor

KV = rpm per volt supplied to the motor so higher = better but that effects your pinion choice or you can start overheating stuff and I'm not an expert when it comes to all the little nuances of pinion/motor choice.

I can tell you the stock motor with a 13t pinion flys just fine, thats what I used in the review thats in the magazine section.

i use my 430xl with 13t pinion as well, and my temps are always in range. I would start with the 430l and then try the higher kv one.
