The Brushed 50Amp is a Brushed Speed Control designed specifically for use in RC model boats. This Brushed speed controller has a 50Amp motor limit and has proportional forwards and reverse functions Marine ESC-50. The hm-50 esc allows remote control of boat electric motors from an RC system. When connected with motor, it is capable of supplying up to 50 amps (forward) or 20a (backwards) of continuous motor current. Its integrated battery eliminator circuit (BEC) powers the receiver from the motor battery, with automatic cutoff of the motor power to preserve receiver power as the battery becomes depleted. It is small and powerful, waterproof, can be used for different type of boat. working voltage 5-10 cells, 6-12volts Specification Continuous load current 50a forward, 20a reverse Weight 82g BEC 5volt Dimensions (mm) 42x47x13
