It sounds like you want to make sure the servo actually reaches the setpoint when you load it with various weights. In one of my college classes someone opened up the servo and soldered a wire to the feedback pot - he needed constant information about the current position of the servo. You could do the same thing to measure the actual servo position for given weights.
yes thats what i may have to do. Do you know where abouts i need to add a wire?
I theory the voltage increase from the pot would increase as i add more weight to the servo, am i right?
