SX Carbon Tail Boom Brace Upgrade - Hirobo HI0404551  [HI0404551]

SX Carbon Tail Support Brace

The HI0404551 tail boom brace from Hirobo is an RC-scale carbon support assembly designed to strengthen the tail boom area on compatible models. Its structural purpose is to reduce flex and keep the tail aligned under load, improving repeatable tail response during setup and flight tuning.

Fit this brace where the stock tail boom support feels soft or when you want a lighter, stiffer link between boom and airframe. The component is supplied 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 a like-for-like replacement using the original mounting points; recheck tail pitch and linkage geometry after fitting to ensure neutral alignment. The carbon material provides stiffness with low weight, so expect to fine-tune gyro gain and mechanical linkages for optimal tail control.

This Hirobo carbon brace is a focused upgrade for pilots seeking reduced tail flex and crisper tail behaviour during setup, providing a straightforward structural improvement for compatible models.
