hi all, new member and first time flying my new beebop 2 using my smartphone in the Arizona desert. I flew it for about 10 minutes and suddenly it dove from about 2o feet to the ground into a dry river bed about a 1000 feet from me . I don't know if I caused it to drop suddenly but it went below the edge of the wash , which is 15 feet lower. I tried pressing the return home option but to no avail as it must have loss contact with the controller? I did hear a noise that sounded as if it had hit a branch just as it went over the edge , so thinking it had crashed I went looking for it. the river bed is full of bushes and small trees and about 1000 feet across and maybe 3 times as long before it turns . I looked everywhere but could not find it. it has been 3 days of searching with no success in a relatively small area . could it have flown out and kept on going even though I had put down the controller? any thoughts on retrieving it now after 3 days?
