Hirobo HI0414203 Tail Pitch Plate Boss Offset 2.5mm for Eagle Freya helicopters  [HI0414203]

Tail Pitch Plate Boss (Offset 2.5mm)

This Hirobo tail pitch plate boss is an RC-scale replacement part intended for the Eagle Freya helicopter parts line. The offset boss alters the lateral position of the tail pitch plate by 2.5mm to help correct linkage geometry without modifying the main tail assembly.

Functionally, the component is used where small positional changes to the tail pitch plate are required to obtain correct pushrod alignment and to reduce binding at end points. In practice this affects how the tail servo inputs translate to tail rotor pitch, so confirming smooth travel and neutral centring after fitment is essential.

Installation notes: fit the boss to the existing tail pitch plate interface and check clearance with the tail boom and tail rotor controls before final tightening. Use the original fasteners where possible and avoid over-torquing to prevent distortion of the pitch plate. After installation, verify full range of tail pitch motion with the rotor held and confirm no interference with the tail case or control horns.

Practical tuning role: the 2.5mm offset provides a simple mechanical method to fine-tune linkage spacing when servo throw, control horn positions, or other setup constraints limit easy electronic or servo-based adjustments.
