Deadstick Bob knows the sound every pilot dreads—the sound of silence. One moment the airplane is flying beautifully, and the next it's become a glider whether he planned it or not. He instantly starts calculating glide angles, searching for the runway, and hoping the airplane has just enough altitude to make it home. When the flight is over, he'll replay every second, trying to figure out whether it was the engine, the ESC, the battery, or simply bad luck. If you've ever celebrated making the runway without power, you've earned the title of Deadstick Bob.
