Mixing Arm for Freya FFZ-III Helicopter - Hirobo HI0414387  [HI0414387]

Fitment and Compatibility Notes

This RC-scale mixing arm is supplied as a replacement part intended for use with Freya FFZ-III helicopter models. It performs as the linkage that transfers servo output into the swashplate mixing geometry, combining collective and cyclic inputs during setup and trimming.

Installation notes: confirm correct orientation and alignment with the swashplate and servo linkages before final tightening, inspect ball-link clearance throughout the full control travel, and verify neutral positions and control throws at the transmitter prior to powering the model. Carry out minor fit checks to ensure smooth motion and avoid binding in the control path.

Tuning role: this item helps deliver consistent mixing behavior when you set swash geometry and collective pitch, making it a practical part for trimming and pre-flight linkage inspections.
