I may have to register it, but I haven't yet, that I'm aware of. . . unless creating the dji fly account and linking the drone to it is what registered it. I know if it's over 250g you're supposed to register it. This one only weighs 400g, but still need registered.
I took it out a few minutes ago during lunch. I went to 400' and I was really pretty surprised that there isn't aa much of a difference from 200' as I tight there would be.
Only thing I dont like so far is it only records 3minute clips of video. If you record 9minutes, its broken into 3 clips. I wonder if you can change that?
I do like the videos from a "cinewhoop" drone like this though. It looks like you're flying through the forest, like in Evil Dead,

.
Now i'm just trying to find some nice places to fly it without getting into a national park or pissing off a gaggle of Karens. I thought I could do some of Townsend, but it's listed the same as the Smoky Mountains, even though its not in the Smokies. I can fly in Pigeon Forge and Gatlinburg though. I think i'll try the river going up through Walland, into Townsend. . . by the UT Ag campus. The ag campus has a huge field with some giant sprayers that might look pretty cool.
