It ain't really running away that bothered me, Jake, it's when they turn and attack----LOL! Back in the early 1970's I ran tether gas powers cars. All there was to that was fire it up and drop it! Stand there and watch it until it ran out of fuel! Speeds were pretty incredible though! The grocery store I was doing it on Sundays when they were closed caught on and didn't like me driving nails into the asphalt and started having cops watch!
This drone "supposedly" all you have to do if it's getting away from you is hit the "home" button and it will come back and land where it took off at. It is supposed to automatically do the same thing if it gets out of range of the radio.
