One other thing, though. The use of epoxy or polyester resin combined with
glass again starts the deterioration clock. The glass is permanent, but the
resins are what age so quickly in the presense of UV radiation. Old
fiberglass boats look rough after a few years and will burn like gasoline.
The glass does not age and will be the big mess left after the fire since it
does not burn. Our process doesn't use any resins as one usually assumes
when glass is mentioned. The "temporary cellulose" base dope is used to
fill and tauten only. It can burn off but the glass will remain in place
with little to no loss of strength to the fabric. The late Bill Hale always
used our fabric on his acrobatic aircraft due to the glass acting as a fire
wall to the occupant. Many NASA experimental windmill and wind tunnel
blades have been covered with our glass as well.


Robert, you're starting to sound like a very bad salesman, creating dark
ghost where everyone else sees daylight. Epoxy is not a vampire that
burst into a cloud of dust if the blinds are raised. In fact, the
proper formulation can sit in the sun for years without measurable
effects. I personally plan to take the very unusual step of painting my
airplane to keep it from rotting away in the sun. Where are these
people who don't paint their aiplanes after having paid to get them covered?

Furthermore, if my elevons catch on fire then I will have been burned to
death long before. A quick look at the Delta planform will explain why.
But this begs the question of, "If the FG can take the forces and
stresses of flight without the butyrate without excessive deformation,
then what is the point of the butyrate?" Didn't you say the glass was
glued on with the butyrate? If it's not necessary, why not just tie on
the FG cloth, spray a coat of paint or two, and go flying?

That is not a redundant question or a taunt. I am really trying to
understand the role each of the parts play in your system. I want
enough information to know if I can apply your product, or a variant of
your product, to my situation. I have a firewall already, and I don't
need a windmill or wind tunnel. I need a very light elevon.

On a more serious note, I think I called you Richard in another post.
Do you have practice kits available?
