History:
Dynali was formed in the early 1980s, the Company being formed by Jacques Tonet in Belgium as Dynali, later becoming Dynali Helicopters. First light helicopter produced was known as the Chickinox, being a three-axis machine built using stainless steel and aluminium, more than 1,000 examples being completed.
Developments over the years in helicopter design led to new ultralight helicopters being constructed using carbon fibre. Mr Tonet was joined in the Company by Theirry Blanchet and a new design known as the H-2 was developed, this being initially a 600 kg (1,323 lb) two-seat machine which demonstrated a capacity to cruise fast, high, and economically. This machine was fitted with a 97 kw (130 hp) Rotax 914 [1211-cc] engine.
The company then turned its attention to producing a more powerful variant, known as the H-2S, fitted with a Subaru four-cylinder engine producing 134 kw (180 hp), this offering a greater payload and a reserve of power enabling improved performance in hot and high conditions.
Both models have been available in kit form or as a complete aircraft, the Company producing the aircraft at its facility at Nivelles, 30 km (19 miles) south of Brussels, Belgium moving to new larger premises in 2011. Production continued and examples have been sold around the world.
Construction was of monoblock tubular stainless steel chassis to which all components were attached. The undercarriage was of tubular aluminium skids attached to the chassis. The tail-boom was of aluminium, the rear transmission being by drive shaft driving a two-blade propeller made of composite materials.
First of the type seen in this region was an H-2S VH-BBT5 (c/n 45-031) registered on 27 February 2012 to Daniel Bell of Ebenezer, QLD. Imported by Mr Bell, he had made a trip to Belgium in December 2011 where, with the assistance of the manufacturer, he built this machine at the Company’s facility at Nivelles. This machine was fitted with a 142 kw (190 hp) Subaru EJ-25 engine and was fitted with an eight-blade carbon fibre tail rotor.
A variant was eventually made available as the H-3, this being a lightened model aimed at the Light Sport category which could be fitted with the Rotax 912S engine or the turbocharged Rotax 914. An example of the H-3 EasyFlyer Sport became ZK-HHQ (c/n H3-61-1740) to Karaka Helicopters of Papakura in May 2018.
