Re: Orange Foam

Paul is correct, the blue foam is floatation billets but has other uses, of

finer texture which makes it easier to sand without gouging. It is soluble
in both auto gas and 100LL and must be protected from those.

Paul is also correct that the foam in the wings may NEVER be layered. It
can be sectioned, as in the Q2 plans.

As such, I purchased a few billets from an insulation company here in the

Also be aware that there was a fatal accident involving the failure of a
main wing that had been fabricated from sheets of foam rather than solid
