Come come now - if you'd bothered to check the formula I gave, I didn't !
It was taken as half way with added the proviso about the boss and grip. I
leave to the student the triviality of adjusting the hand position and use of
sticks with odd shapes.
<<Not only must the sticks be parallel, but they must be vertical (in the
fore and aft plane) to start.>>
Wrong - merely multiplies all the arms by cos of the tiltback - the ratio in
the formual is unaffected.
<<Note that this technique will determine static friction>>
Of course, and that's what stops the servo responding correctly.
But let's not use the forum for quibbles. I think the original was adequate
