Don't forget the ratio of the stick pivot point to the bellcrank attachment points is also a factor. It's probably 3:1 or 4:1 depending on how long the stick is, so a 5 pound pull could induce 20 pounds of tension in the cable, but that's still way under 80 pounds. And my control system and ailerons are unlike any other KR that I know of, but I designed the ailerons to have the same surface area at the same effective moment arm about the fuselage roll axis, so it's probably very similar...except for the airfoil cusp, which is another factor that could drive up my stick forces over a plans-built KR2S....
