The wingtips were both "unwarped" enough to fit them to the wing, so I trimmed the r/h one to fit. The lip where the skin sticks out past the last wing rib is about 9/16" which is quite a bit less than the moulded-in recess in the wingtip where it's supposed to nest, so I had to trim about 3/8" or so off the inner edge of the wingtip to keep it from bottoming out on the rib before seating properly.

I installed the aileron and pinned it in it's neutral position per Vans instructions so I could get the wingtip trailing edge aligned, then did a bunch of measuring and trial fits to try and keep the gaps around the aileron hinge as tight as possible.

I still wasn't happy with some of the waviness of the tip, so I cut some foam insulation to airfoil shape and inserted it into the tip to push it out from the inside temporarily.

Everything looks pretty good, but it's only held on with tape at this point. Will likely not drill for nut plates until later. Still need to enlarge tip to aileron gap to 1/4" and have some fiberglass work ahead because the wingtip trailing edge needs to be cut down to match the aileron.
