This to me equates to a special form of genius which combines astonishing levels of coordination with spatial awareness. The pilot has to seamlessly transpose control actions during the display. Now combine that with dives and climbs and flying rotor first. All in all this has to be infinitely harder than Sudoku, Rubik's cube, Tetris or chess. I'm always humbled when I see something like this. Normal choppers? ... this kid would find them too limiting.
