So I'm prepping for my first autopilot follow mode flight. I will be having the bird follow from the front so we can see it < nervous lol. And at an altitude of approx 125' up and a distance of 100'. I will be driving down the road about 1.5 miles and back to the house if the battery last that long. Is 15-20mph to fast for follow mode? Do I just put the RC and tablet in the front seat? Nerves are killing me lol.
