Tail Drive Coupling for Concept 60 (Kyosho H6034)  [KYH6034]

Tail drive coupling notes for Concept 60

The Kyosho H6034 is engineered as a replacement tail drive coupling for the Concept 60 helicopter tail driveline. It links the tail output shaft to the tail rotor drive and is intended to be used when inspection shows wear or play that could affect control response.

Fitting is handled readily by those versed in tail assembly service: remove the tail boom access panel, inspect the current coupling and mating shafts, then install the new coupling while checking alignment and torque on fasteners. Use compatible hex drivers and follow the helicopter manufacturer's torque specs to avoid over-tightening the connection points.

In tuning workflows the coupling is a small but key component for keeping correct tail rotor drive alignment and reducing play that can produce oscillations. Once replaced, verify tail pitch response and perform a ground rotor check to ensure there is no binding and that the tail moves smoothly with control inputs.
