TAMIYA M1025 Hummer Aluminium Hi-torque 25T Servo Saver with Steel Tie Rod HM1025STM by GPM  [HM1025STM]

Technical Overview: 25T Aluminium Servo Saver for TAMIYA M1025 Hummer

This hi-torque aluminium servo saver is a component-level steering protection part for the TAMIYA M1025 Hummer. The design pairs an aluminium housing with a steel tie rod and a 25T spline interface to transfer steering input while isolating impact loads from the servo output.

Intended for upgrade use, the aluminium body and steel linkage provide a stiffer mechanical path compared with stock plastic parts, while the saver still functions to absorb shocks that would otherwise be directed into the servo. The part is suitable as a direct replacement to enhance durability in scale steering systems.

Installation guidance: verify servo compatibility with a 25T spline, position the tie rod so steering geometry and linkage lengths remain correct, and fasten components to recommended torque values. After installation, confirm servo centring, check endpoints and perform a short low-speed functional test to ensure smooth operation.

Tuning and service notes: the servo saver helps limit shock transmission to the servo under impact and can provide a more consistent steering feel during endpoint and trim adjustments; inspect fasteners and linkage wear periodically as part of routine maintenance.
