These digital control boards are the same exact boards that go into our RTR Servo Winch V2.
So if you happen to burn up your RTR Servo Winch V2 (or another similar winch servo) this will be a great replacement!
Each order includes 1 complete replacement unit.
-Maximum of 7.2v.
To install, simply de-solder your original board and solder this unit in place.
Each unit is tested at the factory; however, because you will be custom soldering these they are sold as-is.
