I have a DJI Phantom 4 and enjoy flying it whenever possible. I will admit I am still a novice but working to improve. One of the benefits I get from mine is for the RV I will fly it over the roof and check for possible issues without having to climb up the ladder.
For the house I periodically fly around the perimeter inspecting my gutters to determine when they need cleaning and to look at areas of the roof that are not visible from the ground.
When out in the RV I never fly around other folks sites unless requested and I always ask permission from campground management before I fly. When someplace like the Outer Banks to have to be knowledgeable of where the campground ends and the National Seashore begins because you can't fly at the seashore.
I estimate I have about 1500.00 tied up in mine and that includes a couple extra batteries. I need to get a charger that can handle multiple batteries at the same time.
