DYNAMIC-SWORDBased on the principles of aerodynamics, the DYNAMIC-SWORD is further upgraded from the SWORD by adjusting different positions on the frame accordingly: 12 and 6 o’clock positions are made inward; 3 and 9 o’clock positions are made outward. The blade-like frame structure has a larger sectional area to direct airflow, making returns faster and smoother.
