Inner tube 4" of  stamped perforated tube (300mm long 1.2mm thick)  -

 filled> with very tighly packed fibreglass. The ends of this tube are

sealed

 with a
 > half dome end plate 1.2 to 1.6mm thick.

Will the fiberglass packing survive the exhaust heat of a rotary???

Not likely.

I don't know Don, but I do accept Pauls opinion as it hasn't held up in the
past !
However this is a different design and I did ask the question and he assured
me
that it holds up. I guess only a really good test will prove it one way or
another.
Even though there proven in racing conditions in RX7s, an aircraft is a
different proposition.
