Thanks Floyd and Brian,
The said pipe appears to be epoxy and carbon fiber, so maybe I struck lucky. The pipe is listed in the Bolly book and is recommended for stunt with a launch rpm of around 10,000.
It would be interesting to hear what sort of engine it was used fro. Certainly about .60 for an f3b pattern ship, but F2b? I have an OS 46 VF doing nothing maybe I could use that?
Regards,
Andrew.
