This is an optional KDE Direct Performance Tail Upgrade Kit "V3", and is intended for use with the Align T-Rex 450E PRO (V1/V2/DFC), SPORT (V1/V2), SEv2, SE, SA, S, and XL series helicopters. This part replaces stock Align part AGNH45183. The Performance Tail Upgrade V3 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, this design provides a truly slop-free, high-performance tail that is rock-solid for all maneuvers. The design is a simple retrofit for the stock parts (replaces the stock plastic tail control links), with the ability to be used on all TREX 450 helicopters on the market and installed in a matter of minutes.

The "V3" design is required when using the latest ALIGN Metal Tail Pitch Assembly (AGNH45181/AGNH45179) for proper pitch range and tail authority.

Very nice upgrade - you can get the screws tight and have virtually no drag in the pitch linkage with almost no slop.)
