Tamiya F103 Servo Bracket for Touring Cars F103RM-04 by 3Racing  [F103RM-04]

Product snapshot

The F103RM-04 is an aftermarket servo bracket intended for the Tamiya F103 range, designed to keep a standard servo in the original mounting area while preserving steering geometry. The notes below cover fit, fitting hints, and tuning relevance.

Fitment is aimed at the Tamiya F103 chassis and similar RM variants, matching the common screw layout. This bracket is a straightforward option when replacing a degraded plastic mount or securing the servo for a firmer feel.

To install, place the servo into the mount first and align the horn with the steering linkage center. Fasten the mount to the chassis with the original screws, then check spline alignment and horn orientation before final tightening. Revisit transmitter trims and end points once fitted.

From a setup standpoint, the bracket helps to lock in servo geometry, reducing slack in steering inputs and simplifying repeatable tuning of throw and steering bias. It is intended for hobbyist track and road use.

Use this bracket to replace worn parts or to give a more consistent servo position for predictable steering on F103-based models.
