What tolerances are recommended for gear mesh?

Maintain a small running clearance that avoids tooth interference while keeping contact depth adequate; check for uniform contact across the tooth face during rotation.

Are these gears balanced for high rpm use?

The matched set is produced for consistent mass and geometry to minimise imbalance in normal RC operating ranges; final balance depends on the whole drivetrain assembly.

Recommended inspection intervals for race use?

Inspect gear teeth and bearing surfaces after each event or heavy session, and whenever you notice vibration or unusual noise; replace at first sign of pitting or deformation.
