Race-Oriented 57T Spur for Precise Mesh

The 57T spur gear by 3Racing RC18-031B provides a race-focused replacement for the Team Associated RC18T drivetrain. Its tooth profile and consistent moulding make it suitable for drivers who prioritise repeatable gear mesh and quick tuning between heats.

Performance Notes for Setups

Use this spur to stabilise gear engagement during back-to-back runs. The plastic construction reduces noise and helps protect the pinion in light contact incidents. Pair it with conservative pinion sizes during initial testing to verify motor load and mesh stability.

Installation and Tuning Tips

Mount the spur square to the hub and set minimal but even backlash. After installing, rotate the drivetrain to work the gear in, then verify no tight spots exist across the tooth face. For competitive events, recheck mesh after the sighting lap.

What setup changes with the 57T spur

Expect a modest change in final ratio compared with smaller spurs. Confirm motor amp draw and temperature after fitting, and adjust pinion size conservatively to retain reliability during heats.

How to inspect for wear in race use

Check tooth edges for rounding and look for uneven wear patterns across the face. Replace the spur if you see chipped teeth or if mesh requires frequent retightening to remain stable.

Recommended pre-race checks

Verify gear mesh, secure mounting screws, and perform a short run to seat the teeth. Confirm no binding when the drivetrain is rotated under power and recheck after one practice lap.
