A:Answer Dear Customer, the DJI Mavic 4 Pro achieves a maximum horizontal speed of 25 m/s in Sport Mode and 15 m/s in Tracking Status under windless conditions at sea level. When flying with a 2 m/s tailwind in the same direction, Sport Mode reaches 27 m/s while Tracking Status remains at 15 m/s (data measured in wind tunnel test conditions; please always refer to real-time on-screen prompts during actual flight).Should you need any further assistance, please feel free to contact our DJI support at http://www.dj.com/support, we are always here to help.Best Regards，DJI Support
