Been reading around, and determined that I need 23% of MAC as well as percentage of chord.

What I have is a lower wing forward Stagger wing Bipe Cub. Its a regular Cub with the bottom wing forward of the top wing and its the clipped wing on bottom, full wing on top.
So haw to I figure 23% MAC and percentage of stagger? Since its the SIG 1/5th Cub kit, I have the wing areas of both wings known. I just don't know how to calculate the rest. Bottom wing is full, no ailerons, top standard ailerons, if that matters.
