The Winchmaster is a digital micro winch controller that is direct battery powered. Runs on voltage from 6vlt-15vlt. Save a huge amount of space and weight. Will turn any standard servo into a winch(some servo modification required). Function forward, off, reverse. Or it will power your existing winch. Fully water resistant. Will not work with brushless motors or servos(only for standard 2 wire motors). Extra channel needed on your reciever as well as your radio in order to work.
