Pretty much the same thing as yesterday, but on the other wing. Still have a couple of low spots in both wingtips, so I cut some foam airfoil shapes and used them to push out the wingtips from the inside. both wingtips are pretty much in a shape that I can cut the aileron gap and finish them up, but I don't know if there's any real benefit to doing that yet, other than getting the wingtips out of the way and being able to store them on the wing rack.
