I was zoomed in about 20x tracking one that was moving left at what looked like roughly 100-150km/h. All of a sudden it instantly moves right, you can make this direction change out in the clip.
Then it picks up speed to like double or triple what it was previously in a very short time and ascends in altitude rapidly.
I am talking crazy speeds.
I have drones that can go 80-90km and even that is quite fast but these white things are fucking bullets man they go wherever the fuck they want very very quickly
