Might want to do something with the front wing dowels. These 40 US's have a bad habit of wearing out the dowels fast. I think they've said on here that it's a vibration thing, and the dowels will start to burn because of the friction. My fix was to take some pieces of copper tubing just big enough to go over the dowels...then drill out the holes in the fuselage so the now bigger dowels will fit. No problems after that...
