The ADI Bumble Bee is an ultralight gyrocopter, the first of its kind when it flew in 1983 and still available in plans form for home-building. It was designed by Martin Hollmann after a back injury (sustained in the crash of the ADI Condor) prevented him from flying his previous design (the ADI Sportster) on account of not being able to lift the rotor assembly.
