LEPTON SZM Tail Mixing Arm Upgrade - Hirobo HI0304017  [HI0304017]

Precision tail mixing arm for Lepton linkage

This RC mixing arm is built for use with Lepton-series helicopters configured in SZM layout, providing a defined connection point in the tail mixing linkage to improve predictability of tail inputs and smoother yaw control during tuning and flight.

Its mechanical role is to locate and transfer motion between the swash/mixing mechanism and the tail control linkages, assisting with trim tweaks and better yaw stability. Supplied as an individual replacement piece for routine repairs or incremental setup improvements.

Installation guidance: check existing linkages and mount points for wear before fitting, ensure the new arm aligns with the mixing assembly, and make small adjustments while bench-testing tail travel prior to flying. Use standard hobby tools and follow typical RC workshop safety when handling small linkages and fixings.
