Hirobo HI0304167 Embla EB 11T Pinion Gear for RC Helicopter Motor  [HI0304167]

Overview: 11T Pinion for Embla EB

This component is an RC-scale pinion intended for the Hirobo Embla EB platform and is supplied as model HI0304167. The 11-tooth pinion transfers torque from the motor to the spur, so accurate engagement and fitment are crucial for dependable drivetrain performance.

When replacing or adjusting this pinion, check gear mesh across the engagement surface, verify axial and radial alignment of the motor shaft, confirm the set-screw or fixing is secure, and inspect the mating teeth for wear. Incremental adjustments to mesh will influence rotor feel and drivetrain noise; re-test after each change.

As an aftermarket RC part, this pinion is intended for maintenance, replacement, and gear-ratio adjustment on Embla EB-class helicopters and should be handled as a precision model component during installation and testing.
