This isn't a mystery at all...
A Mavic 3 Pro have a max speed of 21m/s according to spec... a direct headwind of 21m/s will then stop it, & faster winds will push it backwards. DJI states 12m/s as "Max wind speed resistance" ?
A Mini 4 Pro...
This is as vague and meaningless as DJI just giving a number with no definition or explanation.
How would you define the point at which the drone begins to struggle to resist a headwind?
DJI's mysterious and undefined "max wind speed resistance"...
It's not that simple.
The Max Speed in still air that's shown in the specs is misleading.
It's not the maximum speed the drone could achieve, it's the max speed that DJI allows the drone to achieve.
Look at the flight data for a Mavic 3 (or any...
I think it's that simple in practise...
DJI photo drones have always been limited in tilt+speed by the firmware. The drone will be able to make headway at max speed (here meaning ground speed) all the way up to when the (fw limited) tilt angle...
I had a similar experience with my Mavic 3. It took me a while to figure out it wasn’t the drone, but the wind at 300’ was obviously much stronger than where I was standing. Good thing RTH had 25%. I needed all of it. I could hear the motors...
