When the angle between the antenna and the back of the remote controller is  1 8 0 ^ { \circ }  or  2 7 0 ^ { \circ }  , and the plane of the antenna faces the aircraft, the signal quality between the remote controller and the aircraft can reach its best state.

During flight, if there is a poor image transmission signal between the aircraft and the remote controller, the remote controller will provide a prompt. Please adjust the antenna orientation according to the prompt to ensure that the aircraft is in the optimal data transmission range.
