I fly in the Cascade mountains. There are many line of sight <122mAGL flight opportunities that would result in going more than 500m above my starting point. I have done all the FW shenanigans to remove the 500m limit from my Mavic Pro, but DJI Go 4 is hard coded to 500m, as is Litchi. Are there are control apps that will let me fly more than 500m above my home point? Note that I'm not talking about +500mAGL, I'm talking about flying up the side of a mountain. See my post from this weekend if you want the details of one of the planned routes.
