I know what you are talking about and some of these full scale aerobatic airplanes have just about enough power to virtually hang on the prop like a giant scale R/C airplane..but for safety concerns NO ONE is doing this just above the ground like this video shows...which was more the point I was making... plus in this video you can see the pilot with transmitter in the foreground as someone pointed out....
No I’ve never seen it close to gl. Couple hundred, minimum, or you can’t kick out of it.
