Hi, trying to get my NX500 in the air. It has a multi Wii controller and 4 E flight motors and esc's. When throttling up only 3 motors try to lift. The 4th does not turn. If I apply full aileron or elevator to the side with the motor that is not turning the motor then turns and tries to lift just fine but it is not fly able. Is there a setting on the Multi Wii to correct this? Thanks James
