Twin box tail

image.jpg does anyone have any information on box tail designs. I am going to build this in balsa over the next few days and have no idea about cg and stuff. From throwing this one around best guess is 2/3 back from the tip.

Cool design!
Do you have access to the one in the pic? It would be the same location.
