If you use Sparky's ratio and multiply the wing chord on the kit by 0.93 what do you get for a gap?

Of course this doesn't mean that the designer didn't cheat on the chord as well. Also many model makers are somewhat shocked at how large a true scale fuselage is when they draw it out. It may well be that this designer reduced the fuselage width and height because of this If he then kept the wing planform and spacing scale the skinny fuselage will make the wing gap look wrong as well.
