CG for Great Planes Ryan STA-M

Did anyone set the CG at 4-3/16" from the leading edge as the manual says? Have you flown it? That is WAY too far back in my opinion. It is over 33%! I balance all of my airplanes at 25% but never more than 30%. The STA-M. In my opinion where they say to balance will leave you very tailheavy. Any thoughts?

BTW, it is a constant chord wing and only 13" chord.

Lacking any further info, the spar is usually a safe starting balance point.

You are much safer by being nose heavy, than by being tail heavy. You could start at the spar, and make adjustments as you gain experience with your airframe.
