Dynali H3 EasyFlyer

The Dynali H3 EasyFlyer, now known as the Sport, is a Belgian helicopter designed and produced by the Dynali of the Thines district of Nivelles. The aircraft is supplied complete and ready-to-fly-aircraft or as a kit for amateur construction.

Design and development
The H3 was designed for the flight training, utility and personal-use roles. It was designed to comply with the European Class 6 microlight helicopter rules, in particular the French Class 6 Microlight Category, at a gross weight of 450 kg. It features a single main rotor and tail rotor, a two-seats-in side-by-side configuration enclosed cockpit with a bubble canopy, skid landing gear and a four-cylinder, liquid and air-cooled, four stroke 100 hp Rotax 912ULS engine, a Dynali-developed fuel-injected 110 hp conversion Rotax 912ULS-1 engine or a 115 hp turbocharged Rotax 914 powerplant.

The aircraft's gross weight varies from 450 kg for the microlight category, with heavier weights available depending on installed power in other national categories, such as light-sport aircraft. With the Rotax 912ULS engine, the gross weight is 500 kg, 550 kg with the Rotax 912ULS-1 and 600 kg with the Rotax 914.

The aircraft fuselage frame is made from welded stainless steel tubing. Its two-bladed rotor has a diameter of 7.14 m and a chord of 18.5 cm. With the Rotax 914 engine the aircraft has a typical empty weight of 290 kg and a gross weight of 600 kg, giving a useful load of 310 kg. With full fuel of 60 L the payload for the pilot, passenger and baggage is 267 kg.
