Calculated Thirty eight Fox 35's required, each swinging a 10x6 prop.I wonder how many Fox .35s you’d need to line up along the leading edge to get a Lazair airborne. Enough that I bet you’d probably never notice if one quit…

Does anyone know what Gene Yarbrough is up to? Gene was upgrading the Lazair air frame to handle heavy pilots. Last post and other details are in 2019.
Gene was planning to offer a kit. Maybe health issues?
Chappy, we meet again. Super.Although Dale Kramer's Super Floater hang glider eventually used a twin engine set-up provided by Ed Sweeney ( Partner chainsaw twin engine set-up designed for hang gliders), Ultraflight's Lazairs NEVER used Ed's later set-up you describe above. Ed Sweeney used those on his Hummingbird UL (sold under the Gemini International brand). Dale did not like reduction units, believing they were too heavy and less reliable than direct drive. Ultraflight's Lazairs always had direct drives. Several owners over the years built their own redrive units, not the factory. I was one of them, utilizing the original Pioneer engines on my series one Lazair. Chappy
=================Would love to see the E conversion further refined. STILL waiting on better batteries...
what's the film of wing skin? thickness ?The early series 1 shown in the first 2 photos above had a bit thinner skins on the spars, cables instead of push rods in the wings and didn't have rudder pedals. Without the instruments shown, gas and the non-standard extra metal on the wheels, only weighed 142 pounds! The engines (converted chain saw) were rated at 5 1/2 or 6 HP depending on the manufacturer's charts, but because the props limited the engines top rpm's, actually only produced about 4 1/2 HP each. Glide of that model was a bit better at 13:1. Some of the spec's in the posting were mixed up with later, more developed Lazairs. BTW, the gentleman flying that early plane was very tall. Most pilots aren't nearly as cramped looking. I still have mine I built in 1979/80. Mine has rudder pedal conversion, aileron pushrods, a 5 gallon gas tank (original was 2 1/2), a storage compartment behind the seat, a cut-down fiberglass dune buggy seat in place of the original bicycle or sling seat, a wide gear conversion, engine redrives and much larger props, and still weights 10 pounds less than 200. These are very light and strong aircraft.
================================Sorry if i havent read all the posts and if i am repeating another post.
Wayne Winters from Canada has his own version of a Lazair available for sale as plans (maybe a kit?). Other stuff too.
EZ Fun Flyer
I have seen it flying around at Oshkosh and looks really good.
He is a really nice guy.

Happy new year.
================================He makes a version of the lazair...look a little more and you will find it. Call him and ask!
