What about the leverage factor of the stick itself? If your stick in 12" but your attachment point is say 3.5" (from center of torque tube) wouldn't the forces be 12 divided 3.5 =3.4 times what you feel at the end of the stick?
Fred Johnson Reno, NV Mark L wrote? 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.
