In my opinion
People loosing their drone in urban flying are countless.

If you are looking for trouble and flyaways, let's go urbain flying. Not only it's illegal but the main reason why not doing it, are the WIFI interferences crossing all around.
Just think for a minute, the uge quantity of the WIFI network in a city.
As soon as the drone is by itself it is subject to any frequencies spark disturbing it's program and bye bye.
Keep safe flying my friends.

was this suppose to be rant?

Ok then ....

Youpi i have two fans

Thanks for providing an advice. We're recommending using the aircraft in an advisable environment without interferences to prevent incident as well. Thank you for the support.
