HB-Flugtechnik HB-3 \ HB-21 \ HB-23 - a family of single-engine light aircraft, manufactured by the Austrian aircraft manufacturer «HB-Flugtechnik».

In the development of the aircraft family of aircraft HB-Flugtechnik HB-3 \ HB-21 \ HB-23 was used quite unusual design, taken from the early development of the German aviadizaynera, with Austrian engineers were able to adapt the structure of the aircraft so that in fact, of small- the aircraft has also become positioned as a motorized glider, even those not originally was.

During the design of the aircraft, the developers have tried to minimize the actual weight of the aircraft - this was due mainly to the fact that the original here was supposed to establish a low-power motor, other things being equal to a significant extent have reduced the price of the purchase of aircraft of this model, and at the same time, Low-cost service provided aircraft.

The cabin of the aircraft HB-Flugtechnik HB-3, often referred to also Brditschka HB-3, allows you to stay on board for two people - the pilot and the passenger, while on board the aircraft, you can also post and a small amount of luggage - about 30-50 kilos depending on its own weight the pilot and passengers. In view of the structural and technical features carried on board the aircraft HB-Flugtechnik HB-3 different kind of goods is not possible.
