Oops

When using the Fold A Plane (FAP) technique you only glass one side of certain panels until after the folding task is complete. As mentioned in an earlier post, even a light coat of epoxy, even without glass in it, is enough to prevent the panels bending in the way they need to.  One thing to note is that a properly prepared, glassed-on-one-side panel is still a fragile thing; prone to bending the wrong way and breaking. That is what has happened in the pictures. Two smallish panels, that have heavy panels on their outboard ends bent backwards and the foam snapped. One obvious issue with the break is that the panel does not bend in a smooth radius any more.

Bent this way until the foam snapped.

Now looks funny when bending.

 Nothing to do but replace the broken panels with two new glassed-on-one-side panels.
