what is th flight range of the mav pro and has any one done it though looking just at you phone screen and controller

Are you talking about furthest distance out from home point or just total flight distance.
Ive not taken my mavic out more than a few hundred meters but max flight distance so far is 11 klms

Furthest I have done is 6,5 km out, total 13 km return and landed with 5% battery

Hi, Thank you for the inquiry, we do have the maximum range for our Mavic Pro when using the RC and wi-fi. That details will be stated on the DJI GO 4 app as well.  Please see the reference below. Kindly keep us posted in any case you need our help

The furthest out I've gone over a pretty flat desert area is just over 20,000 ft, which is 3.8 miles and 6.1 Km, fwiw.

Keep in mind that OP is in CE region, not FCC!
