Frequently Asked QuestionsEverything you need to know
Will this Hitec HS-81 Servo Replacement Gear Set fit the metal gear (MG) version?
No, this Hitec HS-81 Servo Replacement Gear Set is designed specifically for the standard nylon gear HS-81 servo. For the metal gear variant, you will need the designated metal gear set.
How do I know if I need a new Hitec HS-81 Servo Replacement Gear Set?
If your Hitec HS-81 Servo motor hums or spins but the output shaft does not rotate or slips under load, one or more internal gear teeth are likely stripped and need to be replaced.
Does the Hitec HS-81 Servo Replacement Gear Set include grease?
No, grease is not included in the package. We recommend applying a small amount of plastic-safe RC servo gear lubricant to the teeth during reassembly for optimal performance.
