Thanks for the input on bagged vs molded Supra. Im looking forward to
trying out the bagged Supra. I would prefer to fly bagged stuff anyway,
maybe the bagged Supra will be the plane for me. Been in limbo every since
Fred Sage quit making planes as thats all I used to fly and was plenty
satisfied with them. Want to try out one of Daryls Insanities as well as it
looks to be quite a performer.

Subject: [RCSE] Supra Question??
Im putting together a bagged Supra ala Mike L. fuse/Phil Barnes wings/tail
surfaces. It will be a while as there is a wait on the wings, but that is
fine as Im in no hurry. My question is how do you guys in the know think
the bagged supra Im putting together will stack up against the molded one
now available? I know the bagged one will be lighter but other than that
not sure about anything else.
Thanks, Walter

That's the kind of information I was looking for, thanks. I have seen
some of those links before but not all.
And I guess it answers my question, there are countless variations of the
Supra. I'll be getting a molded one but it seems to be in the spirit of
things I should modify it in some way too. ;-)

Here is my unofficial take on what is a Supra, gleaned from my hours
of research:
There were a handful of people building there own Supra before Kennedy
got his into production, and there are many ways to skin a Drela
sailplane to mix metaphors...
The Supras that were at the NATS this year (Kiesling, Lachowski and
Barnes) were most-likely modified slightly from the Drela design for any
number of reasons. Mark likes tiny fuselages and some of his
construction techniques are a bit too time consuming for mere mortals.
The basic parameters of the plane stay the same, the construction
techniques often differ due to time/material/builder peculariaties.
AFAIK, the wing airfoils stay the same - AG40-AG41-AG42, and most of
the Supras out there are bagged wings. Mark's original Supra was 48oz
and Kiesling said he has three: two 58oz models and one 64oz model, all
of them bagged wings.
As far as wingspans and such go, there might be some confusing the Aegea
130 wing with the Supra wing. The Supra wing is the evolution of the
Aegea 130 wing (which Phil makes for the Mantis). Mark explains the
differences between those two wings on this page:
http://charlesriverrc.org/articles/supra/supra.htm
I've never heard any discussion on changing length of the tailboom, but
the fuselages are often resized as Mark's fuses are tidy affairs with
little wiggle room. Also, I don't think I've ever seen or heard of a
Supra that doesn't use that sweet little V-mount horizontal stab.
I have read quite a bit about spar and wing construction alternatives,
though that could easily take days to sift through.
And finally...
There are a few folks producing individual pieces and parts for the
Supra... Les Horvath of CompuFoamCore.com had a fuse/wing/tail core set
for sale and Bud Elder makes those v-mounts (in varying sizes!). From
time to time you'll see folks offering up Supra fuselages, but they come
and go. The bottom line is that if you really want to *know* about the
Supra, go and read through the links I've posted, specifically the Yahoo
group.
End of last fall, I put together an Aegea Mantis w/ a Luckenbach fuselage
and Phil's Aegea 130 wing. It's like a poor-boy Supra. A lot of the
same ideas, but different, and cheaper (and heavier). One day I might
get my homebrew Supra together.

I have read about the Kennedy molded Supra on the web page, but isn't
that a Drela Design as well?
It seems when people talk about a Supra (glider) it could mean a lot of
different things. Different fuses and lengths, different airfoils,
different wingspans, different wing construction (bagged or molded),
etc...
