Tim,
Click on the following to go to Don Reid's links to early articles on the KR:

The article at:
http://aerofoilengineering.com/KR/sportaviation/Kr73-1.HTM
explains the use of Dynel and should answer your question about what is used
"under" the dynel/fiberglass.
Be careful talking on KRnet about Dynel. You could start a thread that could
last for months and have people in a very excited state.
Don't ask how I know...
To address your question - what I learned is that Dynel is no longer used
because it holds more epoxy and the end product ends up being heavier than the
same part made from fiberglass. Strength of the Dynel is not a factor in the KR
as some early KRs were made with Dynel and came out fine. Kayak builders gave
up on Dynel for pretty much the same reasons.
I don't think you'll have those problems with Carbon Fiber.

A question re KR2 original
plans. Is it correct the original plans of the KR2 show dynal sheathing as
the nominated wing skin..... Dynal offers no structual bennefits only acting as
a skin to paint.It also weighs almost nothing. Out of interest if dynal was /
is used it would not be premoulded. What technique was used, was there a layer
of thin foam underneath the Dynal. ???
