SX Tail Boom Carbon Brace Set HI0404551 Hirobo  [HI0404551]

Lightweight carbon brace for tail boom

The HI0404551 tail boom brace from Hirobo is an RC-scale carbon support component intended to firm up the tail boom area on matching models. It functions to cut flex and help preserve tail alignment when the airframe is under load, yielding more consistent tail behaviour during setup and flying.

Install this brace where the original tail support is marginal or when you need a lighter but stiffer attachment between boom and fuselage. The item is supplied as a replacement/common part compatible with the Eagle, Freya, EX, and SX families and is designed for hobby-grade RC helicopters only.

Fitting is normally done as a like-for-like swap at the original mounting points; afterwards check tail pitch and linkage geometry to ensure neutral alignment. The carbon construction gives stiffness at low weight, so you may need to tweak gyro settings and mechanical link adjustments for best tail performance.

This Hirobo carbon brace is a targeted upgrade for pilots who want to cut tail flex and refine tail response, offering a direct structural benefit for compatible models.
