Status: offline 		I'm Pretty new the brushless world, and I don't know much about it, i have a little knowledge. But I don't know how to calculate the what motor can handle what RPM andat what voltage. (anyone wanna school me?)

I just purchased a 5700k Mamba, I was wondering which battery is best. the 14.8 4 cell, or the 11.1 3 cell. When I say best, will provide the ultimate performance, safely and that can be managed.

Thanks,
Dennis

Status: offline 		Yup, it's definately possible. It's only good for doing a few speed passes between cooldown breaks, but if you are just looking to see how fast you can go...do it. I like to bash around and not have to stop and cool all the time so the 3s on 4600 is what I prefer.
