Effect on Servo Response

This Futaba FUSG29 gear set is supplied as an internal replacement for Futaba S29 and S129 servos, provided without external packing. It is intended to return worn gear trains to correct engagement rather than replace the servo electronics.

Replacing worn gears can reduce backlash and restore crisp centring, which is important when tuning control response. Always verify gear alignment and shaft play before final assembly.

Step-by-step reinstallation: note gear order, fit each gear in sequence, set mesh with the servo horn installed, and verify free rotation across the travel. Standard hobby tools are normally adequate.

Will new gears improve servo centring?

Replacing degraded gears often reduces backlash and can noticeably improve centring and repeatability, assuming the servo electronics and linkage are in good order.

Any tips for setting gear mesh for performance?

Set mesh with the horn fitted and a small amount of static load; confirm there is no binding across the range and that a thin feeler can pass at the ideal clearance if specified.

Can I alter ratio with this kit?

This kit is a like-for-like replacement intended to restore the original gearing. It is not designed to change the servo gear ratio.
