We had a situation where low batteries almost cost us the loss of our flying field. One of our flyers lost control of his plane and it flew way out of the flying area an crashed onto some neighboring property. When he went to retrieve it he got into a confrontation with the neighbor and since we fly at a state park the neighbor complained to the state and our field was shut down for over 2 months. During that time we weren't sure if it was ever going to open back up again and the whole thing started from low batteries.
