I'm not sure if everyones missed the link that tristan posted, but, there's everything to "fear" about pots.

Even the best Linear pots exhibit some degree of non linearity especially near the outer portions of their range.

They suffer from thermal drift to some degree.

Mechanical forces on the shaft (not true to the rotational axis) affect the value at the wiper.

Shocks to the housing can shift values even when the pot isn't being rotated.

And last but not least exceeding the stop at the end of travel usually causes bad things to happen.

Why not revisit Tristans post and have another look at an "active" system with the potential to eliminate most of these problems.

I know that to a team, every Niagara First Team 1680, 1503 and 1114 would caution that if you can find a device for as close to the price of a precision pot without the drawbacks. Try it. 1503 and 1680 won't be going back to pots again if they can help it.
