I went out for some drone flying time at a local park. I had the whole area to myself when I first arrived but a half hour later a bunch of soccer moms and dads pulled up with their orange cones and started setting up downfield. I had to make sure I stayed away from the general area in case I lost control of the Phantom 2.
I added a the propeller guards until I maneuver the Phantom 2 with confidence. I figure it made economical sense purchasing the guards than replacing the props.
