This tail unit holder is an RC-scale replacement part listed as HI0412261 by Hirobo, intended for use with Sceadu SD-G helicopters. The text below focuses on fitment, its role in tail assembly behaviour, and practical notes for installation and setup without implying any full-scale application.
Compatibility is limited to the Sceadu SD-G designation as shown in the product name; do not assume fit with other frames or variants unless confirmed by parts documentation. As a structural mounting component it provides the mechanical interface for the tail assembly and works together with the tail boom, control linkages and the tail servo to maintain alignment and response.
Installation guidance: inspect mating surfaces for wear, confirm alignment with the tail boom and control rods before final tightening, and use thread-locker where appropriate for metal-to-metal fastenings on RC airframes. During setup, check tail-centre alignment and control throws incrementally so the holder's position supports consistent servo travel and predictable tail pitch response.
For model-level maintenance or part replacement, use this holder where Sceadu SD-G compatibility is specified and verify fit before flight testing to preserve predictable tail behaviour.
