The only Light Sport Biplane in serial production in the world, handcrafted for pure flying pleasure.

In addition to its modern design, the Comet is outstanding due to many facts, one being that it is the fastest bi-plane in the world regarding to the speed / power ratio. Another feature for this unique Biplane, which is rare, is that you are able to fold back the wings within minutes and tow the plane home to your garage.

The cockpit of the Comet is able to convert into many different configurations namely, both seats open cockpit, both seat closed cockpit “Bubble Canopy” and single rear “Race Canopy” with front cockpit covered. There is simple access to both seats as the cockpit fairing can be opened. The Comet offers a long luggage compartment in front and an optional compartment behind the pilot seat headrest.

A modern, mechanical flaperon system gives the Comet its high agility, while offering a good low speed handling characteristic, which makes landing the Comet possible even for the average pilots with some taildragger experience.

The Comet is definitely the FK design, which has been stressed to the highest level during load tests and flight analysis.  The wing load tests for example had been driven far beyond the required test limits up to +16/-8 gs (@450kg Aerobatic MTOW). Stress analysis has been done to meet the basic acrobatic FAR23 load requirements and the pilots are protected by an inert gas welded steel frame cockpit, which is very robust and easy to repair.

When registered as ultralight aircraft in most European countries, acrobatic manoeuvres are prohibited - regardless how far the plane is qualified for.
