We've teamed with Hobbico to bring the Mamba Max Pro SCT ESC and Neu-Castle 1415-2400kv motor combo to customers who want to take the next step in speed and reliability beyond their stock brushless setup. Question: So wait a minute, the motor in this combo has a lower Kv than the stock motor, how can it be faster or better. Answer: Kv doesn't equal power – the motors are almost 100% more powerful than most stock brushless setups. Ours are four pole motors, with higher quality components designed for improved torque. So go ahead, gear it higher than the stock motor and you'll really feel the difference – even with the same cell count! This is a 3-4 cell Extreme Short Course Truck Basher motor. Still want to race? There are lots of tracks allowing "550" size motors (like the Novak HV, etc.) and this system is designed to compete against those 550 can size motors. Mamba Max Pro SCT is built for speed, but it's also a torque monster, able to dig out of tall grass, sand, you name it.
