Embla EB Pinion Gear 11T - HI0304167 for RC Motor Drive by Hirobo  [HI0304167]

Embla EB 11T pinion gear summary

This is an RC-scale pinion gear intended for use with the Hirobo Embla EB platform, supplied under model HI0304167. The 11-tooth pinion mounts to the motor shaft and transfers torque to the spur gear, so correct mesh and alignment are essential for reliable drivetrain behavior.

When replacing or tuning this pinion, verify gear mesh and axial alignment on the motor shaft, ensure the set-screw or retention method is properly secured, and inspect mating teeth for any signs of wear. Small, incremental adjustments to mesh and spur alignment will influence rotor response and drivetrain noise; recheck after each change.

Sold as an aftermarket RC accessory, this part is intended for maintenance, replacement, and gear-ratio adjustments on Embla EB-class helicopters and should be fitted and tested as a model-scale component.
