Custom aircraft development and manufacturing – featuring our own coaxial helicopter design

Flysub Kereskedelmi és Szolgáltató Kft. specializes in the design and manufacture of custom aircraft, machinery, carbon-composite structures and equipment.

Patent innovations

The cabin door’s rotational opening mechanism, which follows an arc within the side plane of the cabin, is currently under patent application, while the innovation of the rudder control system is protected by a patent.

Documented reference projects

HeliForce developments, the motorization of the Hungarokopter HC01, Tubolito test aircraft, the racing boat hull of the University of Pannonia, and helicopter rotor balancing.

Years of partnership

We have been working with Hungarokopter since 2010 and with HeliForce Kft. since 2011; both partnerships continue to this day.

Payload capacity with one pilot

The Flysub Multiengine is designed to economically transport a payload of 350 kg with one pilot, or at least 250 kg of useful load with two people, over a distance of 550–600 km.

About Flysub

Engineering precision is at the heart of our work: we design and manufacture custom machinery, test equipment, and carbon-composite structures, from the initial concept through to finished, measured, and tested structures. We also apply our experience in aerodynamics, structural engineering, mechanics, and electronics gained from aircraft development in other fields – for example, in the construction of the University of Pannonia’s Solar Boat racing vessel.

Our own development, the Flysub Multiengine, is a twin-engine, two-seat, experimental-category coaxial helicopter. Its design principles and structural test program comply with the EASA CS-27 regulatory framework. The aircraft has completed more than ten hours of ground testing, both unloaded and at full load, and is currently awaiting the start of its flight test program. The project was implemented with non-repayable funding under the GINOP-2.1.7. KfK grant scheme.
