John, the description is actually in the FAI F4B rules and is called an "overshoot" which is a British term. I reverted to American terminology when I did the posting. Basically the model makes a landing approach (throttle back and descend) and then the pilot decides to "go around" by adding power and climbing. In FAI the model must fly below one meter for, I believe, 15 meters. Naval aviators would call it a "wave off." Most of the overshoots I have judged did not get low enough or stay low long enough. One meter, 39 inches, is pretty close to the ground when your engine ought to be close to idle power.
