What are the disadvantages of the duck layout fighter?

The good maneuverability of the fighter with canard layout is mainly reflected in supersonic section and transonic section, but the canard design also has shortcomings. The disadvantages of canard layout are poor longitudinal maneuverability, poor pitching stability at high angle of attack, great influence of crosswind on vertical tail, great interference of front wing washing flow on engine inlet and small load. There is another important shortcoming. Because the stall angle of attack of canard limits its performance at high angle of attack, canard is generally considered as a canard at high angle of attack in aviation. China's aviation development is not good, so we have to use canard layout to make up for it. You can see that American fighter planes and large thrust engines can even send a brick into the sky.
