I use the mamba 25 in mine... I would suggest the CC because without the ability to adjust punch and start power they can be quite undrivable with all the extra amps ;) Once adjusted correcty they can be pretty damn impressive. This micro was running 30+mph with losi 10250kv motor, 230mah 15c 2s lipo, and the mamba 25.... Not to mention the close to 25 minute runtimes :) Here is a few pics of it rewired more aproppriatly and a added RC18 heatsink... Fits like a charm and not suprisingly performs like a monster in such a light veh. sorry for the low quality pics
Just my 2 cents but hope it helps!
