This is an optional KDE Direct Align T-Rex 550/600 SXT Version Series Main Rotor Holder Arm Set. The Main Rotor Holder Arms, SXT Version, 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 observed. 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.

Finish: Clear anodize, mirror-polish CNC gloss
Weight: 7 g ea. (design is FEA optimized for maximum strength and minimum weight)
