The root airfoil came out 2 1/4 inches thick with the outside sheathing. I wanted to keep the wing as thin as possible at the root to keep the frontal area as low as possible. Only the font spar was cut out the rear spar was left in it's original position, with the battery all of the way forward in the picture the front spar is an inch forward of the battery leads (The battery is 6 inches long).
