It might be like that old rag-top car we've seen tooling down the highway
with the fabric ballooning away from the metal top when the adhesive gave
way. The altered profile might change the lift characteristics of the wing
to some degree I suspect. I read somewhere that anything above 75 should be
rib stitched, but I'm no engineer.

I was reading some information on Fisher Celebrity builders websites
and saw that one builder did not like the idea of glueing the fabric to
the ribs as per the plans. The ribs on the Celebrity are very thin and
he didn't think there was enough glue area for a satisfactory bond, so
he rib stitched.

I also recall reading somewhere that the glue area doesn't really
affect the strength of the bond between the fabric and wood rib ( which
I can't believe )

I know the wing loading of the Celebrity is low compared to some of the
more high performance bipes, but if the glue area is such a concern,
wouldn't it be OK to just increase the rib capstrip width slightly to
give more glueing area? Might only increase the whole airplane weight
half a pound.

Thoughts? Thanks
