- I am currently trying to find other plans than the ones provided on the
site. I uploaded all the necessary things and still cannot get the file
to open. It keeps coming up with a message saying it (e-drawings)
cannot support it. Does anyone happen to have a copy of these plans
they could e-mail me?

Well, Utah is something of a backwater for aviation. As you
enter the state, a small sign on the roadside says "Welcome to Utah.
Please set your watch back fifty years." Ironically, what was once a
joke, now doesn't sound so bad to me... :-)
Assembling a QuadraPlane from separate wing panels just would
not catch on, even here. It definitely was the designer's baby, and was
never intended for the market. It was indeed a reliable unit, but
performance was never equal to the better Rogallo Hang Gliders of the
day, let alone the rigid-wing HGs. It was probably fairly heavy on the
ground, too. Remember, this was what the "other" rigid-wing HGs looked
like, back then:
Klaus Hill (the Fledgling designer) lived in the same small town
as Larry Hall.
Ragwing pilots used to give me flak about assembling my
("complicated") Fledgling with a dozen ribs, two pins and the drag
rudders. (Lately, these same guys are now stuffing 31 ribs into a
modern blade-wing HG, so go figure... :-)
I could make my Fledgling stay down with the QuadraPlane in
normal flight, if I was flying fast enough, and/or holding both rudders
out about halfway, as drag brakes. You needed to be careful, flying
around that QuadraPlane, because it could instantly pivot on a wingtip
without stalling, from level flight; the Fledgling liked to make bigger,
sweeping turns, more like a sailplane.
Really, I think the biggest drawback is transporting the
QuadraPlane, on the roads. It fills a big SUV, even as separate wing
panels; built like a Riser, it would probably need a trailer. Still, it
would make one unique airchair, if you put the right landing gear under

but you can always add ballast, such as sand, to the pilot's
harness. Most harnesses have a dedicated ballast compartment for this
That's a problem that Ive ever had. I solve the ballast equation
through judicious employment of Anhauser-Busch products. Seriously, the
Quadraplane is just neater than heck. I dont know why I never knew of it
as I have always kept a fairly close eye on the sport. I guess being on
Red, from what you describe it was a reliable machine with good
performance. Is there a reason that it didnt catch on.. or was it just
the baby of the designer/pilot and never marketed? Its a nice exercise
in simple geometery & construction.
