If you've used gyros before, could you give me an example of how bad it could drift?

I would just add in a manual adjustment knob on the driver station - let the second driver adjust it one way or the other as needed during the match.

Is there somewhere we can buy a USB knob or something, or do we have to make one? How would you do something like this that could be recognized as a controller by the driver station?

There have been USB breakout boards included in the KoP in the past that let you wire up analog/digital equipment and read it in like a joystick. I haven't looked yet, but I know an ADALM1000 was included in the KoP this year, maybe you can do it with that?
