DJI stuff is awesome. I played with the idea of getting a cheaper Chinese made drone form somewhere nowhere and then decided to go for the good one. Mine is only the Spark as I've never flown before and the thought of sticking a Mavic in the river terrified me. The Spark is awesome, I've done loads of work with it. So the Mavic, as a guess will be even better.
Looking forward to seeing some shots.
