hey all, Anton from team 419 too.

well, after much playing around with it, i finally remembered that when I was on team 97, we had the same problem for a while.

how'd we fix it? DUCK TAPE. I think the knob or wheel that calibrates it is a little tight on some joysticks and tends to uncalibrate itself naturally.

Just tape it or glue it permanently. Or, you can also open the joystick and fix the knob from the inside. It's suggested that you tape it though from the outside to avoid tampering. (I know i tampered with it last year... hehe)

In any case, we've fixed the problem, and i hope this helps other teams.

: : If I recall, there is a calibration button on the motor controllers that allows you to set the middle and end travel of the joystick...that is, without changing your programming at all.

: Yep...you can recalibrate the speed controllers to work with the output that the controller is giving them...next to the LED on each speed controller, there's an inset button that you have to use a nail, pen, etc. to press. Hold that button down, then move the joystick controlling that speed controller to its max and min positions, then let it go back to center and release the button on the speed controller. The LED should flash green if the calibration is successful.
