US--About Glenn Leaver
(and his flying obsession!)
A HALF-CENTURY OF BLUE-SKY DREAMING:
Glenn made himself learn to read at age three, just so he could follow news stories about sputnik, and read the instruction that came with model airplanes. By eight, he was building and flying jet-powered wood-and-fabric scale models. While living in India, he sought out master kite builders and was a competitive kite-fighter among much older competitors. "There isn't a propulsion system or aeroform I haven't investigated", he says, "... gyros, helis, disks and rockets... and the more exotic, the better". At fifteen he pumped gas in exchange for a student pilot license and at the same time took up hang-gliding and collaborated in the construction of homebuilt airplanes. At the acclaimed flying school at Confederation College, Thunder Bay, Ontario, he earned a diploma in Aviation Management, and a Private Pilots License, then qualified for the Commercial ticket. Before he could get his career as a bush-pilot really started though, he contracted a permanent and debilitating autoimmune illness which attacks the spine. A highlight at college was his term-paper "An Operations Manual for an Ultralight Aircraft Flight School", which turned out to be prophetic. (This was in 1979- when hang-gliders had chain-saw motors attached and were known as "Powered Hang Gliders"; the term "ultralight" was as yet unknown.) This research, including a comprehensive Business Plan, was donated by Glenn to a group of fellow graduates. They used it to obtain financing and successfully launched one of Ontario's first Ultralight Flight Schools. This early research led to a life-long, formal study of the History of Aviation and, in particular, the evolution of the Personal Flight Movement. This complete immersion has given him a deep insight into the subject matter, making him uniquely qualified to guide Aeromancer Flight Design Inc. in solving the problem of "The Backyard Flyer".

"Much of the work prior to patenting was a solo effort, for obvious reasons, but a few people have been especially important to the effort--
providing guidance and support at the most crucial junctures. You know who you are.... and a heartfelt thanks for keeping me in the game." G.L.
Founder & CEO
Intrinsic to the concept of Personal Flight is the ability to land and take-off vertically, so as to permit the widest possible choice of destinations. Ideally--it should also include at least some cross-country capability in terms of range--and all with a very minimum of mechanical contrivance. Leaver's 1990 "Explorer" Prop-Copter design embodies these elements, but a reliable autorotation mechanism proved insurmountable.
Glenn Leaver's 2004 "Skimmer" ultralight design employs the slotted airfoil method to achieve excellent low-speed stability. Models could be made to hover if the slightest breeze was present. Also, while not as crash-proof as the Lift-Jet, it was crash-resistant, due to a large planform area and resultant slow rate of vertical descent at low forward airspeeds. For a time, was seriously considered as a full-scale ultralight build.
Amphibious Ultralight Flea. The Great Canadian Aircanoe . Designed by Glenn in 2001 using a Lavolini-inspired, generic tandem-wing flea design as a starting point. A 6-inch hull was added, along with a unique "wheel-within-sponson" landing gear. Full-size ultralight is approx. 50-60% complete.
