HIROBO HI0404521 SX Lever Shaft Set for Eagle/Freya/EX/SX RC Helicopters  [HI0404521]

Replacement lever shaft for SX series

This lever shaft set is an RC-scale spare intended for use with HIROBO Eagle, Freya, EX and SX family models listed in common parts catalogs. The description concentrates on fit, installation context and how the component integrates with control and tail linkage maintenance without asserting unprovided technical data.

The kit replaces worn or bent lever shafts within collective and tail control linkages, helping to restore free pivoting and reduce play at linkage joints. Proper fitment relies on matching the original shaft locations and retaining hardware, so inspect the rotor head and control arms to confirm alignment before final installation.

Installation overview: remove the affected linkage assembly following your model's disassembly procedure, transfer any serviceable bushings or bearings, and install the new shaft ensuring free rotation without binding. Reuse original fasteners where suitable and verify servo horn and control rod engagement after reassembly. Final trimming and cyclic balancing may be required to restore precise control response.
