Need some opinions on a motor

[sw2kid]

if the mmp wouldn't be a good choice in a truggy, how about a buggy? I'm limited with money right now since I will be buying a new buggy soon, I was planning on running the motor that's in my truggy now (hacker c50 13L, about 1800 kv) in a buggy and a quark or the mmp so I could us the Mamba monster in my truggy. If youre running a mamba monster, if you had cogging, how did you get rid of it? I'm running 2, 2s 45c lipos in series.
