As impressive as the plane/pilot in the vid is, it still doesn't come close to the performance of many of the giant scale 3D flights you see. No full size airplane can hang on the prop and then mash the throttle and climb vertically unlimited until the pilot decides to level off. They may be able to hang on the prop but they can't accelerate vertically with the authority a model can. One of our club's members has a 40% Carden Extra with a DA-150 and he flies 3D with it (when he's not flying it prototypically practicing for a competition). He can go from hanging on the prop to whatever altitude he wants without a problem. No full size can do that. Our models are so overpowered compared to their full size counterparts it isn't funny.

See, that just shows how different we as RC flyers are. I've been flying RC for 25 years, model airplanes of various types since the early sixties. I never get bored with it.
