My Cordless Teth-Air saved me recently too. I was side-hilling and lost the sled to the down side and it rolled away from me. It went upside down and landed with trackside up hill and the throttle pinned. I slid down the hill out of control toward the spinning track but before I piled into it I covered my transmitter tag and the sled shut down. By the time I hit it, the track was only spinning slowly. It was like slow motion when it happened but I could not stop my slide because of how steep it was.
