And I'm (we're) telling you, a ten year veteran of FRC mechanical systems, that this 4WD drivetrain might have some serious issues and that you need to test it out before you assume that it will work. We are all trying to help you out here.

The jumping, jittering, unstable turning is VERY characteristic of this sort of drive train; and, as SteveGPage said, it is NOT precise at all, but instead is nearly un-drivable.
