Ditto on that question. I'm assuming it stays in whatever the last position it was told to goto was?

A "field-centric" turret control is possibly one of the coolest things I've seen done control wise in FIRST. A number of teams have done field-centric drives (especially holonomic and mecanums), which is perhaps even more daunting, but you're the first I know of to do field-centric turret control.

I don't know of any circular range of motion joysticks, and was unable to find one (although I did run into customizable joysticks designed for arcade machine enthusiasts, which may or may not be useful to you). Depending on how you have your code written (namely the return to center question), it might be possible to use a trackball though. You'd have to fine tune it for the trackball control and your driver would have to relearn the system, but it could potentially work well.
