This is my setup. Actually I just want to try and see what happen if I didnt do the setting as previous comment. But yeah, I've encountered some problem such as one of the motor suddenly stuck or pause. Maybe because I didnt put any ID or set the slave or master.
This is my dual setup picture and @chaka , that means I need to cut which wire? because im using a bit different color for the wire and got confused. Im also using 2.4ghz mini controller.
