I have not really travelled any further than 100m, I looked for the best spots to take off from using Google earth beforehand looking for any power lines and trees etc then I get to the spot an hour before the planned start time and take a walk to the spot and suss it out using a torch. Go back to van and have a vape and listen to radio for 20 minutes and then head back to the spot with 15- 20 mins, get everything ready and fire up the mavic to get sats, once i have 13+ i switch off, and put battery in pocket to keep it from getting cold...as soon as the first FW goes up I'm away in less than a minute as the MP keeps sats locked in for a while even when off.
I use the radar and GPS lights to guide it back, you could use RTH but I like to stay stealthy, no front leds and keep the GPS light away from where people can see it.
The display I filmed last night was sent to one of the women who runs the school FB page and said she had no idea there was a drone up
