Hirobo HI0304124 EMBLA EB auto rotation shaft for Embla RC helicopter tail assembly  [HI0304124]

Auto rotation shaft for EMBLA EB

This is an RC-scale replacement auto rotation shaft for the EMBLA EB series, supplied under the Hirobo part number HI0304124. It is intended as a direct-fit spare for the tail assembly where the auto rotation function is required during maintenance or repair of the model.

The shaft plays a focused role in tail control and autorotation mechanics on EMBLA EB models; when a tail linkage or tail rotor carrier shows wear or damage, replacing the shaft restores alignment and helps retain predictable tail response during tuning sessions.

Installation notes:

• Verify part alignment with the tail housing before tightening fasteners to avoid binding.
• Inspect associated bearings and linkages while the shaft is removed and replace worn items as needed to ensure smooth rotation.
• Perform a ground test of tail control travel and autorotation engagement after installation to confirm correct function before flight.
