Hirobo HI0404551 SX Carbon Tail Boom Brace Set  [HI0404551]

Carbon tail boom brace for SX

The HI0404551 tail boom brace from Hirobo is an RC-scale carbon support assembly intended to reinforce the tail boom area on compatible models. Its role is structural: to reduce flex and help maintain tail alignment under load, which supports predictable tail response during setup and flight tuning.

Use this brace where the stock tail boom support is marginal or when you need a lightweight, stiffer link between boom and airframe. The component is presented as a replacement/common part compatible with the Eagle, Freya, EX, and SX families listed in the product category, and it is intended for hobby-grade RC helicopters only.

Installation is typically done in place of the existing tail boom brace or as an upgrade in the same mounting points; expect to recheck tail pitch and linkage geometry after fitting to ensure neutral alignment. The carbon material provides stiffness with low weight, so adjustments to tail gyro gain and mechanical linkages may be required for optimal tuning.

This Hirobo carbon brace is a focused upgrade for pilots looking to reduce tail flex and refine tail behavior during setup, offering a straightforward structural improvement for compatible models.
