The new KDE Direct TREX 250 Series Anti-Rotation Bracket upgrade has been released, giving you the highest-level of unmatched elevator control alignment and flight control available today. Additional clearance has been machined into the precision CNC-machined design to give the pilot an extended elevator servo arm motion and additional pitch range, without binding. With the strength of the Aluminum 6061-T6 frame, the canopy posts are now fully supported; providing a rigid standoff for the canopy easily witnessed on the bench and proven in-flight.

Brand-new to the RC Helicopter market is ALIGN’s release of the new TREX 600 PRO, and we are proud to announce the new line of 600 PRO Upgrades to accomodate the new design.
Although the Flybar Kit is the only version currently available on the market, there is no need to wait to start flying Flybarless – the KDE Direct TREX 550/600 Flybarless Main Rotor Housing upgrade is available now. Highly popular by all ranges of pilots (from F3C stylists to Pro-level 3D competitors), the head design encompasses all the best features of optimal Flybarless mechanics into one product. In addition, the KDE Direct TREX 550/600/700 Vertical Stabilizer Mount can be installed immediately to the tail mechanics to provide a more accurate and secure hold of the Metal Tail Case to the Tail Boom for peace-of-mind during hard 3D maneuvers and increased crash-durability.
Keep checking back with us for future releases and more cutting-edge innovation.

FLYBARLESS MAIN ROTOR HOUSING
FOR ALIGN TREX 550/600 SERIES HELICOPTERS
Item Number: AT550/600-MRHFB
Installation Diagram: CLICK HERE
Price: $74.95
Material: Aluminum 6061-T6
Models: all ALIGN TREX 550E, 600E, 600ESP, 600E PRO, and 600N series (replaces stock Align parts #HN6112, #H55007, and #H55007A).
Note: 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 (600 Series): HN6118, TREX 600FL Main Shaft
Main Shaft (550 Series): H55006, TREX 550FL Main Shaft
Washout Arms: HN6114, TREX 600FL Metal Washout Control Arms
Linkages: H55047, TREX 550/600FL Linkage Rod (A) Set
Includes:
- One (1) TREX 550/600 Series Aluminum Flybarless Main Rotor Housing
