Kolb Ultrastar

The Kolb Ultrastar is an American single seat, high wing, strut-braced, single engine, pusher configuration, conventional landing gear-equipped ultralight aircraft that was produced in kit form by Kolb Aircraft of Phoenixville, Pennsylvania and intended for amateur construction.

[1] The Ultrastar features a completely open cockpit with the pilot exposed to the slipstream.

[1] 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 Ultrastar introduced the trademark folding wings and tail that became a feature of future Kolb designs.
