EDM Aerotec CoAX 2D/2R

The EDM Aerotec CoAX 2D/2R is a series of German coaxial main rotor helicopters designed and produced by EDM Aerotec of Geisleden. The aircraft is supplied complete and ready-to-fly.

Design and development

The CoAX 2D/2R was originally known as the FLIP 2 (Fly In Perfection) and is a derivative of the FLIP 1, a conventional helicopter with a main and tail rotor.

The CoAX 2D/2R was designed to comply with the European Class 6 microlight helicopter rules, including the category's maximum takeoff weight of 450 kg (992 lb). Design testing commenced in 2012.

The design features dual coaxial main rotors, a two-seats-in side-by-side configuration enclosed cockpit and skid landing gear with ground handling wheels. The two variants use different power plants.

The aircraft fuselage is made from composites. Its dual composite two-bladed main rotors have a diameter of 6.50 m (21.3 ft). The aircraft has a typical empty weight of 283 kg (624 lb) and a gross weight of 450 kg (992 lb), giving a useful load of 167 kg (368 lb). With full fuel of 48 litres (11 imp gal; 13 US gal) the payload for the pilot, passengers and baggage is 132 kg (291 lb).
