If no one knows, you can use this website to figure it out. Enter 30 for "%MAC Banace Point". Get the other dimensions by extending the leading and trailing edges to a center line on the fuselage. Dan.

Usually@center of the wing tube/ main wing spar will get you in the ballpark for comfortable and safe flight. Research/calculate from there to tweak to your flying stlyle/styles. Of course if it's a bad design, all bets are off.
