These digital control boards were removed from brand new 2015 Tower Pro MG946R servos to help make our RTR Servo winches.
Each board has the factory potentiometer and standard servo control leads still attached. So if you happen to burn up your MG946r (or another similar servo) this will be a great replacement!
Each unit was tested at the factory; however, because you will be custom soldering these they are sold as-is.
Each order includes 1 complete replacement units.
