By: | April 30th, 2014

Belgium-based company Sagita has invented Sherpa, the world’s first helicopter without a tail rotor!

Utilizing a motor that powers a compressor and air intake at the rear side versus propelling the rotor directly, Sagita claims its design will make aircraft 85% more efficient.


  • 2 of each engine rotors propelled by two turbines (driven by compressed air at 212º F)
  • 4.8 ft. wide by 4.1 ft. high cockpit
  • 15.8 ft. long
  • 250 mile range
  • Cruise speed of 158 km/h
  • 5 hour max flight time
  • Altitude up to 2000 m.
  • 573 lbs. and can carry an additional 377 lbs.
