The easy to build Twinstar Mark III is designed primarily as a STOL class aircraft. It has generous wing area, big flaps, ailerons and powerful engine options that make operation from short fields possible. With gross weight of a 1000 lbs. and slow stall speed, it qualifies as an experimental kit build light sport aircraft... Perfect for Sport Pilot. The Twinstar Mark III may be powered by a wide variety of engines from the 52 hp Rotax 503 to the 100 hp Rotax 912S or Jabiru 2200. To handle the more powerful and heavier engines, the Mark III was designed with the larger diameter (6") and thicker walled wing spars along with more ribs and a stronger drag strut. The empty weight of a Mark III with a Rotax 503 and minimal equipment is about 500 pounds. With the side-by-side dual controls, full enclosure, upholstery package, hand drum brakes, Rotax 582, and a 2-blade prop, the Mark III weighs 550 pounds. A fully equipped Mark III with the Rotax 912, battery, brakes and full cockpit enclosure would be about 560 pounds. As you can see, the Mark III can accommodate a wide variety of needs.

The heart of the Twinstar Mark III, the fuselage cage, is made from strong, factory welded 4130 chrome-moly steel. We also use 4130 steel in all high stress areas. SUPERB HANDLING The Mark III, like all Kolb aircraft, utilizes traditional cable and push-pull tube control systems. The Mark III feels solid even in turbulent air.
