How does this happen? Slop is slop. If its present the control arm lengths don't realize it moving or not, it simply exists and is not a variable of arm length, me thinks.
2) Increase the force on the pushrod (important with thin or flexible rods)
If you have thin or flexible rods and you increase the FORCE it will exacerbate an existing problem, FLEX!
With the typical arm lengths we work with, longer is generally better up to a point.
I don't agree unless your specifically talking control arms, a long control arm is always better, but a long servo arm is always undesirable, but sometimes required to achieve wanted throw.
