History:
Kolb Aircraft in the United States has produced a number of ultralight aircraft designs. These include the Firefly with a 31 kw (42 hp) Rotax 447 engine; Kolbra with a 48 kw (65 hp) Rotax 582 and a STOL variant with a 60 kw (80 hp) Jabiru 2200 engine; Mk III Classic with engines from 39 kw (52 hp) Rotax 503 to 60 kw (80 hp) Rotax 912; and the Kolb 600, which was the Ultravia Aero International Pelican manufactured in Canada and distributed in the United States as the Sport 600 by the New Kolb Aircraft Co.
The aircraft was designed to have a low landing speed, reasonable cruising speed and good payload. Most of the Company’s designs have folding wings for hangarage and trailering. Kits have been available from Kolb Aircraft Inc of Phoenixville, Pennsylvania. A number have been registered in this region, including the Twin Star, under RAA regulations.
