A:AnswerThe camera tilts by use of a dial on the top left of the controller. It will go slightly past horizontal and a little past straight down. Basically, a little more than 90 degrees range of motion.
I dont know about the zoom.
A:AnswerThe Best Buy care is over priced and you can only use it once. DJI care can be used twice in one year and is cheaper. But they both cover about the same things. And yes it has follow me feature.
A:AnswerThis is a new model from DJI. There's not really a previous model, but I'd guess you're talking about the Mavic Pro more than the Spark. It's specs are mostly on par with the Mavic Pro, same camera sensor size and 4k ability, but it's half the size or so of the Mavic Pro when they're folded up. The Spark is a silly thing, a toy, and I wouldn't recommend it to anyone, but it seems they borrowed a lot of the design to create this Mavic Air.
A:Answer1) No SD card included in the normal package or fly more combo. The drone does record up to 8 GB of footage/pictures internally and has a micro SD card slot for further expansion. 2) DJI Care Insurance is not included in the fly more combo. Hope this helps.
