Hi: I was asked today to fly approx 450 yards in a straight line over a golf course. I have never flown my drone this distance and found it very difficult to keep the drone in sight, keep it straight, maintain its height and keep away from trees. I also found it hard to control both direction and height while watching the my inspire from a great distance. My client wanted me to fly the 450 yards of the course, keeping close to the fairway and then land the drone on the green as if it were a ball. Then take off again and fly back. Well I tried, and tried, and eventually hit the branches of a tree. The Inspire landed upside down, two broken props, but this appears all the damage. I did have to disconnect and then reconnect the gimbal again when I fired it up and got no picture. Guess I am lucky eh! Anyway, am looking for tips on how to do a flight like this. The course is surrounded on either side by trees, so I have to fly in a corridor. My eye site must be failing because when it is at a distance I can't see exactly where I am, how close I am to the trees and how close I am to the ground. Advise please!!!
