Kyosho H6034 Tail Drive Coupling for Concept 60 Helicopter  [KYH6034]

Tail drive coupling for Concept 60

The Kyosho H6034 is an RC-scale tail drive coupling designed specifically as a replacement part for the Concept 60 helicopter tail driveline. It serves as the mechanical link between the tail output shaft and the tail rotor drive, intended for routine service or replacement when wear is detected during maintenance.

Installation is straightforward for users familiar with tail assemblies: remove the tail boom access panel, inspect the existing coupling and mating shafts, then replace the worn coupling while checking alignment and fastener torque. Use compatible hex drivers and follow the helicopter manufacturer's torque recommendations for fasteners to avoid over-tightening the tail link points.

In tuning and maintenance workflows, the coupling plays a simple but important role — preserving correct tail rotor drive alignment and minimizing play that can cause tail oscillations. After replacement, verify tail pitch response and perform a ground rotor check before flight to confirm there is no binding and the tail responds smoothly to cyclic and collective inputs.
