In metal, look at the Thorp/Sunderland S-18 http://www.t18.net/ And of
course, the Grumman Cats of WWII. ;-

In wood, the Cvjetcovic CA-65 http://www.hinkleymall.com/ca65.html has
a folding-wing option. There are not a lot of them around, though the
design dates back to the 60's. Not sure why - it seems to be a decent
design. But there seems to be more support for the Piel CP-301/328
Emeraude

Falconar http://www.falconaravia.com/ sells plans for a 3-piece wing
for the Emeraude, which allegedly can be built as a folding wing. It
adds about 40 lbs, and is non-trivial to operate. I'm thinking about
it, but would probably modify the design to split the flap (so as not
to have to remove it) and add Thorp-style aileron connections (to
avoid having to re-rig the wing). As I said, non-trivial. Check the
archives of the Emerauder group on yahoo. Also look at this newsgroup
a month or so back for a thread on high-strength hinges.

The Bowers FlyBaby also has a folding wing. Pete Bowers could set it
up or take it down in about 15 minutes, according to
http://home1.gte.net/ikvamar/flybaby/folding.htm/

The Evans VP has a removable wing, but it's not a folding wing. You
have to disconnect the front and rear spars and four braces, not to
mention the aileron cables.


I'm not aware of any folding-wing designs in glass or carbon.

I'm interested in implementing a hinged wing on my to-be-built homebuilt
airplane.

I'm looking for design specs/criteria/criteques describing the
strengths, weaknesses, reliability, and costs of the most used/popular
techniques.

Any good sources?

Do a google on "glider" and "folding wing". There are a couple of
examples. I know the Stemme motorglider has folding wings.

Corrie and Mike,

Thanks!
