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 4500NaN0. 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 6.51NaN1. The aircraft has a typical empty weight of 2830NaN0 and a gross weight of 4500NaN0, giving a useful load of 1670NaN0. With full fuel of the payload for the pilot, passengers and baggage is 1320NaN0.[1] [2]
