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.^[1]

Design and development

[edit]

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.^[1]

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.^[1]

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. ^[1]

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).^[1]^[2]

Variants

[edit]

CoAX 2D: Current production version in 2017, powered by a six-cylinder, liquid-cooled, four stroke 135 hp (101 kW) D-Motor LF39 engine.^[1]
CoAX 2R: Version powered by a four-cylinder, liquid and air-cooled, four stroke 100 hp (75 kW) Rotax 912ULS engine. No longer advertised as available in 2014.^[1]^[2]
