I love Stewarts work!

Good information.

Thanks so much for posting this. When I was researching drones before buying one, I watched hundreds of vlogs and his impressed me the most, not least because he doesn't make the videos all about himself. They're all about the information. (Forum member Kloo Gee is also in that category--lots of good information without any ego-driven posing.) I lost track of his name and YouTube channel after buying my Spark and wished I hadn't. Now I know where he is again.

Course lock is for drones that retract their landing gear.  The landing gear up and out of the way so the gimbal camera can rotate around without body obstructions as the drone heads in one direction.  

Good hints on tap fly.  I think it rejected my target/direction on every other time I tried to use it so I did it manually.  Might have to mess with it more and see if the Spark will rotate while continuing to head in one direction.

nice sharing!
