I've had the urge to build a kit for awhile, so I guess this project will help me relive the good ol' days.
This picture shows the reason the wing failed. Insufficient support structure around the wing tube. It simply ripped the ribs right out of the wing. There should have been a spar box built around the wing tube, not in front of it. Simply poor engineering.
