I’ve got a 4 bladed drone that can run without a controller

I’ve got a 4 bladed drone that can run without a controller. Once in the air it’s programmed to follow you via a tracker beacon and the on board sensors or an automatic computer program. Although it comes with one anyway so you can do tricks and more complex moves, but other than that it’s fully automatic and requires no assistance. I use it for film and checking stuff on my farm.
