I just bought a Castle Mamba Monster 2200kv esc motor combo and i cant decide what car i should put it in. My choices are Slash 4x4 or Rustler Vxl. Also i don't know what parts and gearing i would need to put the system in. So if someone could tell me what i need to buy that would help. And i need help with batteries for the Mamba Monster plus a couple other systems. The ones i need help with are Castle SideWinder SCT with 1410 3800kv motor and Castle SCT Race Pro with 1410 5mm 3800kv motor. I already bought 2 batteries. But i don't know if they will work good enough for either the Mamba Monster or the others. The 2 batteries are
Gens Ace 5000mah 40C. Any advice would be a lot of help.
