Throttle return kit for FS-12FZ and FN

The Tamiya 54777 Throttle Return Springs are intended to pull the throttle back to a neutral position, offering a mechanical safeguard if the throttle linkage or power system fails. They promote steadier throttle response and safer vehicle behavior.

Compatibility notes

Specifically produced for use with FS-12FZ and FN engine setups, these springs are a practical add-on for owners focused on reliability and straightforward maintenance.

Do these work with aftermarket throttles?

They can work with many aftermarket throttle arms if the mounting and travel are compatible. Measure linkage geometry before fitting to ensure correct return action.

How do I set the return position?

Adjust the throttle linkage so the engine idles where you want it, then fit the spring to give a firm but smooth pull back to that position.

What signs indicate a worn spring?

Look for reduced return force, visible stretching or corrosion. Replace if the spring no longer holds the throttle reliably at idle.
