Re: one control stick or two?

What I do want to mention is what Jonathan mentioned and I quoted. We had the same issue where the robot would "drift" because of the motors running in opposite directions. What we did is install a "jack shaft" on one side between the motor and the gearbox. What this did is allow both motors to run in the same direction and thus the same speed.
That stick control toggle thing is what I wanted last year. That, IMO is the perfect tank drive system. As for the motors running in the same direction, usually what's done to remedy this is having a change gear of the same size and pitch as the last gear, which it mates to on the end of the problem gearbox, thus reversing the direction of rotation and equalizing speed.
