What is the effect of a 79T spur on gear ratio tuning?

Using a 79T spur shifts the overall gear ratio. For precise lap time tuning, adjust pinion increments and monitor motor temperature and RPM to balance acceleration and top speed.

How should mesh be set for race use?

Set a tight but non-binding mesh with minimal backlash to ensure repeatable engagement. Recheck mesh after break-in runs and after any drivetrain changes.

Are there specific maintenance checks for racing?

Inspect tooth form and runout before events, confirm secure mounting hardware, and replace the spur if any teeth show deformation to avoid inconsistent lap times.
