The MP is really small when packed up - very portable. Drone, controller, 3 batteries and all the odd and ends fit nicely into a mini Smatree case I have. It's amazing it all packs down that small when I compare it to a P3 or P4. Noticeably quieter as well.
The trade-off is camera quality. It's good enough for what I do, but if you're into more pro level stuff I suspect you'd have more stringent requirements than average Joe shooters such as myself. The
M2P seems to be changing the game a bit, however.
