The GetSome wing build is very simple and just like every other 2mm wing that you've built up to this point with a couple of minor exceptions.  Notice that the spar does not go all way to the tips.  This is a two fold reason why.  The first is it reduces weight and the second is I sealed the wing tips.  Also the spar is only 3/4 inch high.  This will yield a wing that is 1 inch thick.
