Easy pinion swap for better gearing control

The Tamiya 50477 - 24T, 25T AV Pinion Gear set provides a simple way to fine tune gear ratios on compatible models. These pinions support step changes to drive behaviour without extensive drivetrain changes.

Which models will accept these pinions

These AV-style pinions are compatible with many Tamiya kits that use AV mounting. They offer a convenient method to try different gearing profiles for varied track or terrain conditions.

Practical fitting advice

Fit the pinion with careful attention to mesh and alignment. Use the correct set screw and apply a small amount of thread-lock if you want to prevent the screw coming loose under load.
