I fly mine through a trail in the woods behind my house. I just have to navigate about 50 to the trail. Even then its REALLY tight and lose gps. I haven't brought the craft down yet but I have clipped a few leaves and branches in the beginning. The props hold up quite well. I came all the way home once only to notice half of one was missing. We got some creepers messing around back there and seeing them watching a machine navigate the forest with no operator in sight is just awesome and worth the challenge.
