A "soft" action can bend and spring back under firing stress as long as the strain (deflection) does not exceed its yield strain. If it does then the soft action will bend and stay bent.

Rocket I get your point about the .002" being very thin compared to the rest of the cross section of the action but I make the point again that the strength of a monocoque fusealage is primarily due to the thin skin held in place by bulkheads and runners. And the maximum tension strain is most likely at the surface, as is the maximum compression strain.

I am glad to be here.
