Hirobo HI0304044 Lepton Series Tail Shaft  [HI0304044]

Lepton tail shaft: role and fit

The HI0304044 tail shaft serves as an RC-scale replacement for Lepton-series Hirobo helicopters, forming the primary connecting piece in the tail drive. It transfers drive motion to the tail rotor and helps preserve alignment between the main drive train and tail rotor components.

Installation notes: before fitting, check nearby bearings and linkages for signs of wear or play, ensure the shaft seats correctly in the tail case and that spline engagement is clean without forcing parts, then verify tail pitch and tracking after reassembly. Use recommended thread-lock products and follow the torque specs in your helicopter's manual.

Tuning role: the tail shaft contributes to drivetrain runout and tail responsiveness; correct installation helps lower vibration and makes servo and linkage setup more predictable.
