Hirobo HI0304124 Replacement Tail Auto Rotation Shaft for EMBLA EB  [HI0304124]

EMBLA EB tail shaft replacement

This is a scale replacement auto rotation shaft made for EMBLA EB tail assemblies, supplied under part number HI0304124 from Hirobo. It serves as a direct-fit spare where the autorotation function of the tail needs to be reinstated during service.

The shaft helps maintain proper tail control and autorotation behaviour on EMBLA EB airframes; when linkages or the tail rotor carrier show wear, fitting a new shaft restores correct alignment and supports consistent tail response when tuning.

Installation notes:

• Check the shaft sits square in the tail housing before you tighten fasteners to prevent binding.
• While the shaft is out, inspect bearings and linkages and replace any worn components to preserve smooth rotation.
• Carry out a ground check of tail travel and autorotation engagement after fitting, then perform a cautious hover evaluation to confirm performance.
