Mine had apx a .040" gap at the trailing edge. If you think about it the rubber bands that hold the wing the the fuselage are near the leading edge so even if your'e inboard rid are true you may still have a slight gap. I have personaly seen one fly with more than a 1/8" gap in the leading edge of the wing. Personally I wouldn't worry about a small gap at the trailing edge but would worry about gaps at the leading edge.
