Did the initial install of the leading edge skin on the left wing. This went a lot quicker and easier after have done it on the right wing. I repeated the same steps. I'm happy with how it came out - I still have a lot (hundreds) of additional holes to drill in the side skins. Then I'll drill them to size. I strongly recommend that basic kit builders do the wings last - their much more complicated than the fuselage. If it was easy it wouldn't be fun.
