Something to think about when flying down a ditch line, between houses, don't if you can help it. Fly over every thing, don't be afraid to get some height on your bird when you initially take off and get your bird out in front and I would say at least 40 meters (120 feet) in height, as a minimum depending on height of trees, you want to fly over the trees and still have line of sight on the bird. Next, ditches can have all kinds of power lines, phone lines, water lines, gas lines, etc running their length and buried. So, for a low flying Phantom, they can cause major flight problems. I know, I have had my P2 do a couple of crashes because of them and don't forget barbed wire fences with steel angle iron posts. The P2 taught me how to fly my P3P and P3S and what to be careful of and around.
So, all in all, stay well above houses and trees when flying.
