Hirobo Sceadu Evolution FZ-4 Mixing Arm HI0412213  [HI0412213]

Swash Mixing Arm Information

Hirobo HI0412213 is the mixing arm intended for the Sceadu Evolution FZ-4 rotor head assembly, forming the linkage that manages mixing of cyclic and collective controls. Correct geometry is key to consistent head response.

This part is presented as a direct replacement or spare for Sceadu Evolution FZ-4 models where precise mixing and predictable cyclic behaviour are required. When fitting, verify pivot seating and free play, and confirm swash travel and servo endpoints following reassembly.

Minor adjustments to mixing arm alignment or play will change pitch curve and cyclic authority; re-assess hover trim and low-speed stability after fitting. It is intended for RC hobby use only and not for full-scale vehicles.
