Fit the wing tip, matched to t.e. trimmed gaps etc. The aileron to tip gap is supposed to be 1/4" per print, so I cut it to 3/16" with my dremmel and then sanded up to the line to get the full 1/4". The tip fits pretty nicely at this point. Only off on the t.e. maybe 1/16" or so. The T.E. of the tip has a little wave in it, so I'll likely try to manipulate that a little bit when I trim it to match the aileron, but I think I'll wait on that. Once I got the aileron mounted, I was able to sight down it and the tip and discovered that not only does the tip have a little wave in the t.e., so does the l/h aileron. This is a bummer, but I don't thing it's bad enough to warrant rework. If it flies funny I'll manipulate it then. Also drilled mounting holes to #40. Took it back off, then cut and final fit the nav light lens.
