Performance Tail Upgrade V2 for ALIGN T-Rex 450 Electric Series Helicopters

Product has been archived, and is no longer available for purchase. This page is for reference only.



Update: All current production now includes (2) SAE 660 Bronze Bushings for compatibility with all versions of the ALIGN T-Rex 450 Series Tail Pitch Assemblies.

The Performance Tail Upgrade V2 provides superior tail control for sport and hard 3D flying styles. With dual flanged, radial ball bearing supported tail grips and precise machining tolerances for the brass bushing sleeve, the new design provides a truly slop-free, high-performance tail that is rock-solid for all maneuvers. The design is a simple retrofit for the common ALIGN parts on the helicopter (replaces the stock plastic tail control links), with the ability to be used on all T-Rex 450 helicopters on the market and installed in a matter of minutes.

Looking to install the new ALIGN Metal Tail Pitch Assembly (H45181/H45179)? The "V3" design is required for proper tail pitch range and control authority.
