Looks nice, and I'm sure ou will be happy with the finished product. Just a FYI, the leading edge on the 4 Star contains 'turbulators' (or so I was told by a fellow RCer) They are designed to 'mix up' the air, especially at slower speeds, to stabilize the wing. As much as a floater as the 4 Star is, though, sheeting the LE will probably help with the landing. Full scale Ag planes actually use turbulators attached to the wing in all sorts of crazy looking configurations. This is to help them evenly disperse chemical.
