No, you will have one stick that move X/Y horizontal direction and the camera you control on the other stick.I'll have to test this cause I am getting a little confused. In course lock, is the speed set by the pilot? so I couldn't just set course lock and put the controller down like in waypoint mode?
Thought just read manual, but nothing. DJI support video, nothing
There is this video to show what can be done after you manage it:
and this to shows how to do it with the stick (first part):
In fact you need to pilot it with direct view on the Mavic (means really close range), not from screen and track your video subject using the Go4 app screen.
The trick is to separate both functions (pilot and film maker) in your brain, one stick for pilot and one stick for film maker.
All these filming can be done also without course lock but it is just much more harder.
