I guess you mean tensile strength of the tape + resin, not the whole
structure, but I'd a guessed more than 30.  However, there's stresses
---From several directions here -- up/down in Gs, aft in drag, and twist
(flap and aileron).  But as to G forces, she tested beyond 10Gs, so
maybe now 9Gs due to the tape problem?  Who knows. We need only 3.8G for
utility category safety, though, but I understand the conundrum, is all.
