This is an optional KDE Direct TREX 550/600 Series Main Rotor Holder Arm Set, and is intended for use with the Align T-Rex 550E (V1/V2), 600E/ESP, 600E PRO, and 600N (V1/V2) series helicopters. These Main Rotor Holder Arms are designed as a bolt-in upgrade for the latest ALIGN Metal Rotor Holders to optimize the cyclic/collective control geometry for Flybarless flight. By extending the arms further from the central Main Shaft and optimizing the mounting location for perfect, 90 degree alignment to the flight mechanics, increased servo travel and resultant control resolution is obtained. The arms were extended to provide a 8-12 point increase in Collective Travel and Cyclic Throw for the Mikado VBAR Flybarless System, as well as increase the resolution for the BeastX Flybarless System (resultant blue light) and other mainstream systems.
NOTE: Assembly requires the latest version of the ALIGN Metal Main Rotor Holders for proper installation (AGNH60204).
