Tail Pitch Plate Boss for Eagle/Freya/EX/SX - Hirobo HI0404322  [HI0404322]

Role of the tail pitch boss

The Hirobo HI0404322 tail pitch plate boss is supplied as a replacement RC part for use in the tail pitch assembly of the compatible models. It forms the mounting point between the pitch plate and the tail linkage, giving a stable pivot and locating feature for the pitch mechanism.

Built to slot into the tail assembly with minimal fuss, the component helps maintain correct pitch plate alignment, limit side-to-side play in the linkage, and preserve repeatable geometry for reliable pitch control. The description is written for hobbyists carrying out standard maintenance, component replacements, or minor control adjustments.

Installation notes: confirm the existing linkage geometry prior to removal, adhere to the model maker's torque recommendations for fasteners, and verify unobstructed movement through the full pitch range once installed. Small incremental tweaks at the boss or plate are recommended, with flight tests after each change.
