SXT Main Rotor Head System for ALIGN T-Rex 550/600 Series Helicopters
The new KDE Direct 550/600 Series SXT Main Rotor Head System provides the most innovative and engineered control mechanics to install confidence in any flying style. Every detail was scrutinized and continually reviewed to provide the ultimate system for Flybarless flight control, providing the latest technology for fast-response and smooth flight characteristics tailored to your own flying style.

- Optimized main rotor grip arms for Flybarless control.
- Innovative clamping mechanism signature to all KDE Direct head designs.
