It is fully programmable using Hi Tec's programmer. The combination of torque, speed, price and extreme holding power make it a favorite among pilots. new premium high speed HS-7985MG Digital Servo has the added benefit of our 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 high performance coreless motors, dual ball bearings, bushing supported gear shafts, dual ball bearing output shaft and our Heavy Duty Metal gear train the HS-7985MG will give you everything you need no matter what the demand. 172oz @ 6V, .13 Sec @ 6VFULL SPECS: Control System: +Pulse Width Control 1500usec Neutral Required Pulse: 4.8-6.0 Volt Peak to Peak Square Wave Operating Voltage Range: 4.8-6.0 Volts Operating Temperature Range: -20° to +60° C (-4°F to +140°F) Operating Speed (4.8V): 0.16sec/60° at no load Operating Speed (6.0V): 0.13sec/60° at no load Stall Torque (4.8V): 144oz/in.
