ok, to go with mode 4, that will be easy because you wont have to move the throttle. On the inside there will be 2 electrical components next to each of the joysticks. what you are going to to is take the wire off of one of the pots that lays horizontally, and move it to the other joystick. Make sure to match up wire colors, and to test the resistance of each pot, and make sure you are getting the same readings. If you are, then you are all set =)
