The XMC300 electronics speed controller is one of the world’s smallest ESCs and has been specially designed for the XRAY M18 micro racecar. A high competition speed controller suggested for high competition – a “must have” for serious racers. Based on SMD technology, the result is a very small high-quality electronic device. This forward-only ESC features proportional throttle and braking, and battery elimination circuitry (BEC).
