Aircraft
We took off from ZZZ in normal conditions. At approximately 1;600 ft.; the pilot flying had problems with the controllability of the aircraft. The PIC took control of the aircraft and confirmed the actual problem - the aircraft was turning left by itself; without any reason. To maintain heading it was necessary to use abnormal force to the right with the aileron controls. The rudder pedals apparently were stuck. To maintain 2;000 ft. that was required; we asked for radar vectors to returned to ZZZ. ATC gave us vectors to downwind for Runway XX and cleared us for visual approach. Speed was 170 kts. We made an early turn to base leg making us too close to Runway XX; so we decided to ask for vectors for an ILS to Runway XX. Vectors were given to us and we performed an ILS; with a safe landing. The conditions with the flight controls were present till our landing. After we left the runway; we stopped and then were followed by the fire truck. When we started to taxi in again; the rudder pedals were apparently with normal deflection; so we continued to the ramp.
Citation pilot reported experiencing a stuck rudder shortly after takeoff.
