Spindle component for Concept 60

The KYOSHO H6004 spindle shaft is supplied as a direct replacement for the Concept 60 series spindle. It links the rotor hub to the transmission stack and restores axial alignment, reducing the free play that can disrupt rotor tracking.

During repairs: remove the rotor head and retaining parts, check surrounding ball bearings and gear faces for wear, fit the replacement spindle into the original seating, confirm smooth rotation and correct endplay, then secure fasteners and re-check blade tracking. Proper seating and bearing condition are essential for the intended function.

Swapping a worn spindle often eliminates vibration sources and restores predictable rotor response; after install perform a balance check and a controlled hover test before normal flight. Keep spare shafts clean and lightly lubricated to prevent corrosion during storage.

Remark :
Due to limited stock availability, please notice that some Kyosho items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

How does this part improve rotor tracking?

By restoring correct axial alignment and removing shaft wear, the H6004 reduces play between rotor and transmission, which tightens tracking and reduces erratic blade motion.

What should I inspect before flight after swapping the shaft?

Check bearings and gear interfaces, verify smooth rotation and minimal endplay, rebalance the rotor blades, and conduct a low-throttle hover test before full-power flights.

Can I use this spindle on modified Concept 60 builds?

It fits standard Concept 60 assemblies that accept the H6004 designation; if your build uses non-standard housings or custom bearings, verify dimensions before fitting.
