Tail Autorotation Shaft Compatible with EMBLA EB - HI0304124 Hirobo  [HI0304124]

EMBLA EB tail autorotation replacement

This item is an RC replacement auto rotation shaft designed for EMBLA EB series tail assemblies and uses the Hirobo reference HI0304124. It is supplied as a direct-fit spare for servicing or repairing the tail where autorotation capability is required.

The shaft supports tail control and autorotation mechanics on EMBLA EB builds; replacing a worn shaft helps restore correct alignment and keeps tail response consistent during trimming and flight testing.

Installation notes:

• Confirm the shaft is aligned inside the tail housing before tightening fixings to prevent binding.
• While the shaft is removed check nearby bearings and linkages and renew any worn parts to ensure smooth operation.
• Complete a ground validation of tail travel and autorotation function after fitting, then carry out a restrained hover trial to confirm correct behaviour.
