The Kiss 209M is a single rotor, conventionally laid out helicopter seating two side-by-side. The design targets were low cost and easy maintenance, combined with a comfortable cabin and good performance. The centre section and the high-set tail boom are tube steel structures, clad in carbon fibre. The cabin shell is also carbon fibre and bolts to the central frame. The 120 kW (160 hp) Solar T62 turboshaft engine is supported above the cabin roof and tail line, partly exposed, driving twin blade main and tail rotors. The latter is accompanied at the extreme tail by a fin/underfin pair, both swept and slender. A narrow pair of tailplanes is located forward of the tail rotor on the boom, though the prototype initially flew with a T-tail. The Kiss can have either a skid or retractable wheel undercarriage.
The main rotor advances to the right and the anti-torque tail rotor, mounted on the left side of the tail boom, advances at the bottom. The semi-articulated main rotor is supported on an underslung teetering hinge. Pitch inputs to the main rotor blades are transmitted via rods inside the hollow main rotor shaft.
Control of the Kiss is conventional and manual. Dual control is an option. It is fitted with an electronic flight instrument system (EFIS).
After ground runs on 15 July 2009, the Kiss flew for the first time on 13 August. The first production aircraft completed company testing at the end of January 2011 and went to the Aéro-Club de France for a six-month evaluation.
