hey guys,
i just decided to give my old MRS4 a revamp. so i ordered a sweet Penguin RC 3500LM chassis for it, with micro servo mounts. i'm throwing in all new electronics, including a Mamba package.

i will probably be racing it in the micro class at my local club, nothing fancy or particular about it. what Mamba system should i get if the track will be built for 1/10 gas/electric sedans? will the 5400kV be a good choice? i am not looking for stupid fast speeds with tire shredding power, i want the system that i can control and be able to use to its fullest. i'm not sure what gearing i'll be running, so i might need some help on that too.

by the way, if i do get a brushless system, i should probably use metal pinions, right? i am guessing that the plastic ones would just spin right off.
