Technical counter gear for FF-03 competition setups

This 20-tooth counter gear is offered as a technical replacement for the TAMIYA FF-03 gearbox train. It functions as the secondary gear meshing with spur and pinion to determine final drive ratio and transmit motor torque through the gearbox assembly.

Compatibility is with FF-03 type gear trains that accept a 20T counter gear; confirm part profile and shaft interface before installation. The part is intended for tuners who need to restore worn drivetrain components or adjust final ratio for circuit-specific performance tuning.

Installation follows standard gearbox servicing procedures: remove the gearbox cover, extract the existing gear, inspect and, if necessary, replace bearings or shafts, install the replacement with precise tooth mesh and backlash settings, and reassemble. Validate engagement with a controlled test run and monitor for smooth rotation to ensure optimal durability and performance.

What checks should a tuner perform before fitting?

Measure shaft runout, inspect bearing play, and compare gear profile to the original to confirm correct alignment and mounting orientation.

How precise should backlash be set?

Set minimal, even backlash that allows free rotation without binding; verify under light load and after a short break-in to confirm stability.

Do tuners need to replace bearings at the same time?

If bearings show wear or excess play, replace them during service to prevent accelerated gear wear and to maintain precise mesh during competitive running.
