Center of Gravity was created by smartrobert

I am not shure if this question is on the right place here, but could anybody gives me a tip where I can place the Center of Gravity CG?

Is it at 1/4 of the airfoil lenght meassured at the main rib, or behind it? Has anyone a metrical size for this position?

Thanks for helping,

Robert

As far as the Bellanca Super Decathlon model published on this web is concerned, the CG was located at the center of the main wing joining tube, which is 160 mm from the leading edge of the root airfoil chord. Having the airfoil chord 720 mm provides the position of CG at 1 / 720 * 160 = 22%. Having the CG located at 25% would work as well, as the model was slightly "nose heavier" anyway.
