This is a Futaba MSA-10 Servo Synchronizer, and is intended for use with giant scale aircraft that require multiple servo control. This servo synchronizer couples up to 4 servos, and electronically balances them to start and stop simultaneously for strong, smooth operation of even the largest control surfaces. This synchronizer also allows for individual adjustment of end points and servo travel for each servo. It also features reversing, so servos can be mounted in the most efficient configuration possible.
