 Hi all:

         Has anyone done carbon parts w/ Plexiglas windows? I'm curious
 about the way different T-sub-C of carbon vs. Plexiglas and also
the difference
 from fibreglass, too. I'm going to use an inflatable seal on this
 e-exit/baggage door,  so that's not a worry...

 Regards,
 James

It is a worry if the gull wing door rips off because it opens in flight.
Lots of trouble along those lines so far with the KIS line.
One accident I think. On a 172 or 182 with the doors hinged at the
front it is not a problem.

For what its worth, i recently received the quickbuild gullwing door
for my Lancair ES and it is totally carbon.  Unlike the Lancair IV,
the ES is mostly S-glass.  It was delivered with the plexi-glass
window installed.  I figure there must be a pretty good reason for
Lancair to make the door and frame out of carbon.  It also uses an
inflatable door seal.  Anybody know of a cost-effective lighweight
pump for this sort of application?
