Bobcat elevator servos
tony is exactly right..............by putting the linkage out further on the servo arm you change the geometry ( aka leverage ) servos get their inch oz rating by being "linked up " at a set distance from the axias..........once you go to a hole further out on the arm you loose leverage and inch ozs
with leverage us 250lb linebackers can stand those 350 lb linemen up like tent poles............without it all you get is a bus ticket with a box lunch
