I live in the bottom of a valley with 800 meter tall mountains on either side of me, so the altitude limit of 500 meters on the Mavic Air 2 is really bugging me since it makes it very hard to get the shots I want. I've been looking in to editing the firmware to allow the drone to go up to 1km up in the air so I can see above them but I'm not sure if the drones which use the DJI Fly app can be modified the same way older drones using the Go4 app could?
