If you're going for speed, the lower CG of the Rustler is way better. I agree with the kite statement, it seems 100% true from the vids i've seen. I'd just gear it as low as you can in 32P gears.. Should have tons of torque, great runtime, and decent temps. I'd personally go for a Mamba ESC if you can. They are only 115 new and shipped. IMO worth every penny more.
