Hirobo HI0304017 LEPTON SZM Mixing Arm — tail mixing arm for Lepton RC helicopters  [HI0304017]

Mixing arm for Lepton helicopters

This is an RC-scale mixing arm designed for use with Lepton-series helicopters, intended to control tail link motion as part of the rotor mixing system. The part focuses on providing a precise connection point in the tail mixing linkage to aid in predictable control inputs and smoother tail response during setup and flight tuning.

The component role is strictly mechanical: it locates and transmits inputs between the swash/mixing mechanism and tail control linkages, helping with trim adjustments and fine tuning of yaw stability. It is supplied as a single replacement part for hobby repairs or incremental upgrades during setup sessions.

Installation notes: inspect existing linkages and mounting points for wear before fitting the new arm, confirm alignment with the mixing assembly, and perform small incremental adjustments while bench-testing tail control travel before flight. Use standard hobby tools and follow usual RC workshop safety practices when handling small linkages and fasteners.
