I have clocked in 80km/h with a tail wind.
But I think you can adjust the max tilt angle of the drone and make it go faster (not that i would recommend it )
@ianzone, maybe you left the handbrake on for that flight?
Best I’ve done with my P3S is about 58mph with a returning flight tailwind. Flying in heavy winds aloft is not in my comfort zone, so I rarely try for airspeed numbers.........but nearly 80 mph is really impressive. [emoji106]
