This is a USA muppet moment as told to some of us by a club member who had visited a flying site there. A group who were co-owners of a large-scale model were first to the site this day. Although they used a peg-board system, as they were fist there, they didn't get their peg. Our club-member arrived and joined the group of fliers. As the tx was being passed between them, it was passed to him. After a short fly, he passed it on. Just after he had passed it on, the next flyer lost control and the plane crashed. Reason: another flyer had arrived, and finding his freq peg on the board, took it and turned on his tx, unfortunately the same freq as the plane already flying. Body bag, please.
