  • Combining gearbox with light weight clutch enables rotor to enter autorotation in cruise flight
  • Elegant streamlined hub greatly reduces drag enabling greater speed and cruise efficiency
  • Advanced Scimitar Props enable anti-torque for hover. Unique design achieves both high static thrust and high speed cruise efficiencies
  • By using a combination of thrust and moment due to rotor tilt, the aircraft can remain level in hover over a wide CG range
  • Multi-speed automatic transmission operates props at efficient rpms for both low and high speed flight
  • Reversing props can work as air brakes
  • Wing tailored for cruise efficiency enabled by high lift rotor for hover and low speed flight
