Correction of wingtips part 10 - trim and reprime wintip skins 8

A 2mm step between the edges of between wingtip skin 8 and top skin 5 was present, both wings, with skin 8. This was blended, by removing the excess material from skin 8 by filing. On the bottom side the smaller step of about 1mm was dealt with the same way. In order not to remove too much material near the tail of the wingtip skin topside, and note to interfere with the bottom edge too much, a slight change in angle of the wingtip skin edge relative to the top skin edge was accepted.
