Oh no! Sorry for the loss, bigG. I hope you were able to salvage your motor/equipment. Sorry to hear this. I finished the shear web mod yesterday on mine, but haven't recovered the bottom of the wings yet. When I inspected the structure the other day, I remembered that you posted that the carbon tube looks to be too short. A lot of the problem looks to be that there isn't much carry-through structure from the tube socket to the rest of the wing. This causes a highly stressed area just past the tube socket, with only an upper and lower 1/4" balsa spar to handle the load for the most part (albeit with two layers of shear webs after the mod). I also noticed that the vertical balsa sheet piece (actually two pieces) that's above and below the tube socket is split past the tube. The factory didn't bother gluing this piece (at least) or adding a doubler piece. I added some vertical grain 3/32" balsa in this area.
Well, after hearing of yours, I'm going to take another look and come up with some structure to help better transfer the wing loads from the end of the carbon spar and socket. It does look too short, but then again my friend's Comp ARF Integral carbon tube spar looks really short to me too. That's why I'm leaning towards the above thoughts...
