*Digital servos do not need to be programmed to operate. They work great right out of the box and purchasing a programmer is not necessary.

Replacing the HS-5955TG, Hitec’s premium high speed HS-7955TG 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 Titanium gear train the HS-7955TG will give you everything you need no matter what the demand. We offer the HS-7955TG servo in several configurations, 90° stock rotation, 180° modified rotation, continuous rotation (potentiometer is left outside the servo case) and reverse rotation.

Programable Features:
- Dead Band Width
- Direction of Rotation
- Speed of Rotation (slower)
- End Points (up to 180 degrees)
- Neutral Points
- Fail Safe On/Off
- Fail Safe Points
- Resolution (default is set at high)
- Overload Protection (default is off)
