Precision 38T Composite Spur Gear from Serpent

The Serpent 904200 38T composite spur gear is aimed at modellers who expect steady drivetrain behaviour. Its composite construction is chosen to balance durability with lightweight operation for consistent track performance.

Long-Lasting Tooth Strength

With 38 teeth this spur provides fine control over torque and speed for tuning. The composite helps minimise wear common with some metal options, extending service intervals and preserving driveline efficiency.

Broad Compatibility and Use

The Serpent 904200 is compatible across many RC platforms and is useful for both competitive racers and hobby mechanics. It gives a reliable replacement option when refreshing your powertrain components.

What pinion sizes work well with a 38T spur?

Pinion choice depends on motor and desired top speed. Typical pairings use common pinion tooth counts for your chassis; check final drive ratio calculators to decide.

Is this suitable for brushless setups?

Yes. The Serpent 904200 works with brushless motors, but ensure correct mesh and motor cooling to avoid excessive heat transfer to the gear area.

How do I check for correct mesh without gadgets?

Use a strip of paper between teeth, tighten the spur mount, then rotate to check for light drag. Recheck under low power and after a short run to confirm the setting.
