Restore Rotor Drive with Walkera HM-4G3-Z-16

The Walkera HM-4G3-Z-16 Main Gear is a direct replacement designed for the 4G3 helicopter. Precision tooth forming helps maintain smooth torque transfer and keeps the main rotor running true under regular use. Replace the gear after wear or impact to keep flight characteristics consistent.

Why Choose This Main Gear

  • Compatibility: Tailored for installation on the Walkera 4G3 platform.
  • Durability: Made to handle frequent flying and routine landings.
  • Performance: Aims to reduce vibration and support steady rotor speed.

Is extra machining required to fit this gear?

No machining should be necessary. The gear is made to the Walkera 4G3 specifications for direct replacement.

Will swapping this part change handling noticeably?

If the original gear was worn, installing a correctly fitted new gear will restore expected handling and reduce any irregular rotor behaviour.

Any tips for installation and setup?

Make sure shaft seating is clean, check mesh with the pinion, and verify there is no side play before flight.
