Thanks for the breakdown. I'm considering adding either this or a mavic pro to my equipment. When in their bags they take up about the same space. I'm considering the spark because it's small size makes it less intimidating in public places because people see it as more of a toy. The mavic because of it's portable and does 4k. I already have one 4k drone, a Yuneec Typhoon, but the mavic would be much more portable.
PS- Include a couple of stills from the spark next time and you'll probably get more views. Right now the thumbnail for this post is blank. Just some friendly advice.
