Radio control airplane movie flying acrobatically with transcendental skill

It is completely different from how to fly a regular radio control airplane. It makes a transcendental flying way in every sense. Perhaps it is probable that the pilot can not bear this shock on ordinary realistic airplanes, is it possible?

Playback is from the following.

I tried collecting other similar movies.

Apparently it seems to use such an airplane.
