HS-7985MG Servo
Details
The new HS-7985MG High Torque Digital Servo has the added benefit of Hitec's new G2 second generation programmable digital circuit. This circuit has twice the resolution of our original circuit while adding programmable overload protection. The technology doesn’t stop at the circuit board, with a high performance coreless motor, dual ball bearing supported output shaft, bushing supported gear shafts and Hitec's Heavy Duty Metal gear train the HS-7985MG was designed to withstand the stress of larger high performance aircraft and on/off road vehicles.
