This tail unit holder is an RC-scale replacement part listed as HI0412261 by Hirobo, intended for use with Sceadu SD-G helicopters. Presented below are notes on fitment, its contribution to tail assembly behaviour, and practical setup guidance without implying any full-scale application.
The holder is specified for Sceadu SD-G compatibility only; verify part dimensions before assuming fit with different models. It acts as the structural mounting point for the tail boom and works in concert with control linkages and the tail servo to keep geometry stable.
Setup tips: inspect and clean mating surfaces, align the tail boom prior to final torque, and use a thread-locking compound on metal fasteners where appropriate. Tune control throws incrementally after installation to confirm smooth and predictable tail response.
For maintenance or replacement tasks, fit this holder only when Sceadu SD-G compatibility is confirmed and perform cautious flight testing to ensure stable tail control.
