I have a Mavic Air 2 with a 8.5-10 m/s level 5 Wind Resistance speed. I also have Mini 2 with a 8.5-10 m/s scale 5 Wind Resistance speed. What is the difference between scale 5 and level 5, as the 8.5-10 m/s for both drones is the same ? I understand the Mavic Air 2 has a stronger wind resistance, but unable to clarify the wind speed specs for both drones. Hope someone can clarify this.
