SK - 20 Pillager

update
This is a statically unstable forward-swept wing stealth fighter with a duck-wing configuration. It is equipped with a powerful engine and extraordinary aerodynamic design, providing it with excellent maneuverability. Its VIZZY flight control system is quite complex.

For the pitch axis, it adopts a closed-loop control of angle of attack (AoA) and angular velocity, with PID parameters automatically adjusted based on the speed and AoA. This ensures excellent controllability under different flight conditions.

For the yaw and roll axes, it uses dynamic decoupling control combined with angular velocity closed-loop control to effectively eliminate coupling between yaw and roll, resulting in smoother flight. The inclusion of a first-order filter enhances disturbance rejection, enabling precise control.

In addition, the fighter is equipped with five different maneuver modes to meet various requirements. It also features cruise control and landing assistance, which are essential functions. Of course, if you prefer, you can disable the flight control system and switch to manual control.
