Tip-up configuration. My outboard (curved) sub-panel flanges don't lay flat on a flat table at all. I assume I should be fluting these to straighten them and line the holes up prior to fitting the skin, but 1. the plans don't call it out, and 2. I don't see any other builder's logs that mentioned having to do this step. Are my flanges just unusually warped from the factory?
