The FireFly is a significant breakthrough in ultralight aircraft. Easy-to-build and designed to be a legal ultralight under FAR Part 103 with the 40 HP Rotax 447 engine installed.  We have observed that most legal ultralight aircraft suffer from a lack of performance.  We, at The New Kolb Aircraft, think flying an ultralight aircraft should be safe, fun and affordable.  Pilots should not have to give up performance when flying an ultralight.  So we have designed the FireFly to be a “real” aircraft with a level of performance that can fly rings around other ultralight aircraft.  After all, who wants to drift around like a kite when you can be buzzing through the sky like a fighter?  The FireFly also offers the mainstay features all Kolb aircraft are know for: quick-folding wings, encloseable cockpit, welded chrome-moly steel fuselage cage and, of course, outstanding performance in 254 pounds than any other manufacturer.
