takeoff

Hi! I am trying to takeoff with my m300 without GPS at all. I switched the controller to Atti mode but with no luck. Is there a way to bypass this DJI restriction?

I was several times given a unique opportunity by the captains of the seaplanes at the resort, to film their takeoff at sunrise. We did this in full cooperation with the captains and crew (no drone regulations are in effect), using a spotter and staying behind the aircraft at takeoff at all...
