Diamond DART 280

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 MTOW helicopter could haul a 556 kg payload, cruising at 145 knots while burning 35 L of fuel per hour.
