The HS-985MG is quickly becoming a favorite of ours.  The power of this servo is great, especially considering the price. This is also one of our favorite servos to put in our ServoPower Gearbox. We offer this servo in several configurations, 90 stock rotation, 180 modified rotation, continuous rotation (potentiometer is left outside the servo case) and reverse rotation.

This servo can operate 180 when given a pulse signal ranging from 600usec to 2400usec. Since most R/C controllers cannot generate this wide of signal range, you will need to purchase our servo stretcher for 180 operation.
