OK BrianG, so let me know something. I've order a 1512 1.5d, 3200Kv, with a Max curent of 135A. I'll use it on 11.1volts. If i consider a gearing of about 40m/h, is this motor will pull more amps from my li-po than if i would have take a 1509, 2d, 3300Kv, 95A, for a same gearing

And what about heat and efficiancy???
