Simple throttle safety for FS-12FZ FN engines

The Tamiya 54777 springs force the throttle back to a neutral setting if control is lost, reducing the chance of overrun or engine stress. They help maintain steady throttle positioning for safer operation of your RC car.

Who should use these springs

Manufactured with FS-12FZ and FN engine installations in mind, these return springs suit racers and weekend drivers who want a reliable mechanical safeguard without complex setup.

Can I fit these to my stock throttle arm?

Most stock throttle arms for FS-12FZ and FN setups accept these springs, but check the mounting point and clearances before final installation.

Do they affect throttle feel?

When fitted correctly the springs provide a predictable return without noticeably changing throttle modulation for normal driving.

Are any special tools needed to fit them?

Basic hand tools and a small pair of pliers are usually enough. Make gentle bends only and avoid over-stretching the spring.

Will these springs stop engine stalls?

They help prevent unintended wide-open throttle conditions that can damage the engine, but they do not address fuel or ignition problems that cause stalls.
