The Hummelbird was designed by Morry Hummel in 1980. Like all other aircraft in the Hummel fleet, the Hummelbird is an all metal construction. The aircraft is small and efficient yet rugged, rated for 6G's. The Hummelbird was designed to use a 1/2 Volkswagen. Contact us for information about engine suppliers.
The aircraft, like it's sister planes, is extremely maneuverable and efficient. Unlike the Ultracruiser, it does not fall under Part 103 of the FAR (Federal Aviation Regulations). This means that the aircraft must be registered to the FAA, and comply with any airworthiness standards. This also means that the pilot in command must possess the appropriate licenses and medical certifications. The builder (you) must also complete 51% of the aircraft to comply with the FAA experimental light sport requirements. Luckily, the plans for this aircraft are easy to read and easy to finish. Most builders can complete the aircraft from scratch in 1200 hours. Although Hummel Aircraft Company only sells plans, and not kits for the Hummelbird, many parts are available for purchase.
