Ok, so without going into too much detail about why I need to do this, I have a question...

My intention is to disassemble a servo and 'fool' the amplifier into thinking it is in one position when it is in another. What I mean is, the steering on my truck requires roughly 9 turns of a lead screw in order to move from lock to lock. The typical servo feedback pot only turns somewhere around 180-210 degrees. I would like to gear the pot off the lead screw so that it moves the same short distance while the motor goes much further. I know that the larger the error between where the servo is positioned and where it is directed produces a higher speed rotation and this may give me the steering travel time I am hoping. I simply wish to force the motor to turn further than the pot when directed. I hope this makes sense.

So, where's the question?

Right here: Has anyone done anything similar? Like, fooling the servo amp in order to get more travel from the motor?

I ordered a $9 no-name digital servo from eBay in hopes of testing this idea, and I will post the results if anyone would like the information.
