I tried doing that with my Mavic Pro 2 and the controller... Ya that did not end up working well at all,lol... Ya when it zooms in/out its in gps mode and I assume its having a hard time with the gps data. A few times I could see it go from eyesight to gps /back again and I knew exactly how the footage would look.. Luckily its doing better with keeping my rig in center frame... Well I know I am learning but thats more of changing the drone positions to a better suited location due to whats around me. And ya it did strike a small branch "again" but it recovered like it was nothing and kept going. So far I think its gone down like 2 times with a couple blades needed replacement. Still fewer so far than my Mavic (took all 4 out once,whoops).....
