I used to fly home built quads at hammonasset until I discovered it was off limits, even had a park officer tell me he was going to shoot it down.
With the MP I have flown numerous areas, fields, farms, if you fly away where there aren't any people, I've never run into any problems.
I also use Litchi almost every flight. If it is a mini, Litchi will not work for missions, not sure if it will work with the mini at all. I would love to buy the mini, but the lack of being able to set up missions in advance keeps me from buying one.
