Re: Fuel Tanks
You are correct Dave.The light glass cloth was used because they thought a
heavy coat of straight epoxy might crack. My 12 year old Q1 tank is fine. Some
of the EZ's around here have 20+ years and 3000 + hours with car gas also
and no problems.
I recall hearing that Rutan and the EZ guys went to the very light
fiberglass cloth like they use on RC models to give the extra epoxy
coats on the inside of the tank some structure and to reduce the number
of pin holes. Perhaps Terry Crouch can comment on this or some of the
other guys familiar with the EZ's.
