The H2S was designed to comply with the amateur-built aircraft rules, but a light-sport aircraft category version, the Dynali H3, is also being developed. It features a single main rotor, a two-seats-in side-by-side configuration enclosed cockpit with a windshield, skid-type landing gear and a four-cylinder, liquid cooled four-stroke, 165 to 185 hp (123 to 138 kW) Subaru EJ25 automotive conversion engine.

The aircraft fuselage is made from a combination of aluminium tubing and welded stainless steel, covered with a polycarbonate fairing. Its 7.22 m (23.7 ft) diameter two-bladed rotor has a chord of 20 cm (7.9 in) and employs composite main rotor blades. The tail rotor is of an enclosed Fenestron type with eight blades. The aircraft has an empty weight of 465 kg (1,025 lb) and a gross weight of 700 kg (1,543 lb), giving a useful load of 235 kg (518 lb). With full fuel of 80 litres (18 imp gal; 21 US gal) the payload is 177 kg (390 lb).

Like many helicopters designed in France and Russia, the main rotor blades advance to the left.
