Eddie;

Your description is that of a wing that flexed under flight loads, and due to continuos oscillation and MAY BE lack of glue in the spar area, it prevented the wing from stopping to flutter. Since there is no damping at this point, the wing will continue to oscillate to failure. Aileron flutter seems not to be the cause from your observations. There was some talk ( as above ) of some wings that escaped proper gluing processes.
I have a Razor composite kit and one day I may finish it or sell it, but overall I am not happy with this product's quality and this does not make me feel any better
