Turns out the axis at the base of the joystick was "twist" and "z" (I think), but the actual "twist" axis was called "throttle". So even if you think you know what you're doing, things can surprise you.
You quickly figure that one out on your own BUT NEEDS TO BE NOTED. I had my first ever PID controlled drive train attack me. Encoders needed to be reversed. Error ran away
