The Flybarless Main Rotor Housing upgrade encompasses the latest technologies for optimum setup of the flybarless mechanics.  The new design incorporates a series of performance enhancements including:

1. Direct-mounted washout arms to guarantee true-parallel alignment of the linkage rods and an interaction-free setup to the main shaft. No more hassles with the main shaft clamp and difficult linkage alignment, simply bolt on the washout arms and go fly with and optimal setup every flight.
2. M3 clamp mechanism is built into the upgrade design, providing a solid hold to the main shaft that is truly noticeable in flight with a significant reduction in shaking, bobbing, and other effects evident under hard 3D flights.

Design Notice: To achieve the best possible setup and perfect alignment of the flight mechanics, it is recommended to use the following ALIGN flybarless components with the new design:

• Main Shaft: H50133, T-Rex 500 FL Main Shaft
