Just picked it up yesterday. Haven't flown it yet, or shall I say crashed yet. Hopefully the weather tomorrow is decent. If all goes good Maybe I'll post some video. supposed to be 4K quality
I would suggest the Phantom4 pro. a little heavier it has sensors for the trees and such. Plus any kind of wind, I think the mavic will struggle a bit. Was actually talking with brother in law about doing this. I'll let you know how the mavic handles in the wind.
I flew my phantom 3 twice this weekend and now I cant wait to fly again. Still need a lot of work but I was definitely scared more than I should've been. Its pretty easy to fly and the auto hover is amazing. I need to get the video off the SD card and then I will post it.
Im thinking if you got one of those little GPS tracking chips and put in your dogs vest, the Drone could follow that signal. But then again if you get a tracker you could follow on your phone. They are real cheap now and you can put it on anything and track it.
I had a blast with this thing.
Mikeg if your a little scared to fly it, put it in Tripod mode. In this mode no matter how hard you push the sticks, it will not travel fast at all, and you have movements in all directions. I did the follow an object thing. I didn't do the set a path thing. But this was definitely worth the money.
