I noticed that I was getting a bump in the leading edge from the tip ribs. After doing a bit of research I decided to relieve the the ribs at the tip just under the edge of the flange. I drilled 3/16" hole and then trimed back a slot to each hole. This frees up the flange to move a bit and shouldn’t create the bump in the leading edge. I’ll probably make a new leading edge skin as well.
