This is the Dynamite 8000Kv C4 brushless motor. When combined with high-capacity, high-power NiMH or Li-Po batteries, Dynamite’s new C4 brushless motors offer incredible amounts of power in a compact, lightweight design. Built specifically for mini vehicles like the Mini-T and Mini-LST, the C4 brushless motors feature high-strength magnets for intense acceleration and torque, and they are pre-wired with gold-plated bullet-type connectors for drop-in installation. Combined with a brushless ESC (not included) they make for an incredible power package for mini vehicles.
