The Kolb Mark III is a family of American side-by-side two seater, high wing, strut-braced, pusher configuration, conventional landing gear-equipped ultralight aircraft that is produced in kit form by New Kolb Aircraft of London, Kentucky and intended for amateur construction.[1][3][4][5][6]

The Mark III's standard engine was originally the 64 hp (48 kW) Rotax 582 engine, but the current engines offered are the 80 hp (60 kW) Rotax 912UL or the 100 hp (75 kW) Rotax 912ULS. In its home country the aircraft is normally licensed in the Experimental - amateur-built category.[3][4][5][6]
The design features a forward fuselage of welded 4130 steel tubing, mated to an aluminum tailboom. The horizontal stabilizer, tail fin and wings are also constructed of riveted aluminum tubing with all flying surfaces covered in doped aircraft fabric. The wings and horizontal tail are quick-folding for storage and ground transport. The original Mark III can be made ready to fly from trailering in eight minutes by one person without the use of tools, while the newer M3X variant is rated at 15 minutes to assemble for flight.[3][4][5][6]
The landing gear is sprung tubing for the main gear, with a steerable sprung tailwheel and the cabin is 45 in (114 cm) in width.[4][5]
Factory options include brakes, Ballistic Recovery Systems airframe parachute and powder coating of the steel parts. The manufacturer describes the aircraft as STOL, with a 200 ft (61 m) take-off run.[2][6]
In reviewing the aircraft Andre Cliche said:
| “ | The Twinstar Mk III is a very clean and aerodynamic design. lt looks fast and flies fast. With standard dual controls, it can be used as a trainer but it is most often used as a cross-country cruiser. It is especially desirable for its folding wings.[4] | ” |
