ok, the problem with going right when you hit forward is, one of your motors is wired backwards... Simply swap the pos and neg on one of the motors to the speed controller and that will be fixed. (if you swap one and when you hit forward you go backwards, then you need to swap both of them again because you swapped the wrong one) As for the sensitivity, i don't know about that. It could be that your robot is geared to high and you have way more speed than you need anyways.
