The Chinese specialized attack helicopter Changhe Z-10 demonstrated the "pendulum turn" (hill turn/pedal turn) aerobatic maneuver during demonstration flights in the air program. The maneuver demonstrates the high maneuverability of the vehicle, the stability of the dual-turbine autopilot system and the precision of control at extremely low altitudes and at speeds close to zero. The Z-10 is equipped with a 23mm PX-10A autocannon and hardpoints for ATGMs (AKD-9/10/21) and Ata-90 air-to-air missiles.
