Tune Your Eryx 411 4.1 with a Machined Pinion

The Serpent 120171 Aluminum Pinion Gear is crafted to refine the performance of your Eryx 411 4.1 Touring Car EP. Featuring 32 teeth and a 48 pitch, this hard-aluminum pinion reduces rotating mass while offering strong wear resistance. It is a practical upgrade for hobbyists focused on drivetrain efficiency and consistent lap times.

Advantages of a Hard Aluminum Pinion

Hard aluminum delivers a useful mix of strength and lightness, which helps maintain fast acceleration and reliable gear engagement. The machined finish on this pinion helps ensure smooth meshing with the spur gear under race conditions.

Compatibility and Fitment Tips

Made specifically for the Serpent Eryx 411 4.1 family, the pinion installs without major modification when matched to the correct motor shaft and set screw. Precise machining aids straightforward alignment and dependable service during frequent running sessions.

Will this pinion work with brushless motors?

Yes, the Serpent 120171 will work with brushless motors as long as the motor shaft diameter and pitch match. Check your motor shaft size and secure the pinion with the correct set screw to avoid slippage.

How do I check gear mesh after installation?

Install the pinion and spur, then set the mesh with a thin sheet of paper between the gears. Rotate the drivetrain to seat the teeth and retighten the pinion, then recheck mesh to ensure even contact without binding.

Can I run this pinion as a direct replacement for a steel unit?

Yes, you can replace a steel pinion with this aluminium unit for reduced weight, but monitor wear over time since aluminium can abrade faster than hardened steel in high-torque setups.
