  The DART 280 is a four-seat light-single piston-engined helicopter concept by Austrian Diamond Aircraft.
  
  ## Development
  
  Launched at the April 2017 AERO Friedrichshafen, its first flight was scheduled for October 2018 and certification a year later. Its development was later put on hold until it has a viable market.
  
  ## Design
  
  Intended to compete with the Robinson R44, the composite aircraft will have a 280shp (208kW) four-stroke jet-fuel engine, energy absorbing retractable landing gear and a shrouded electric tail rotor. The 1,350 kg (2,980 lb) MTOW helicopter could haul a 556 kg (1,226 lb) payload, cruising at 145 kn (269 km/h) while burning 35 L (9.2 US gal) of fuel per hour.
