All of those I have seen, other than the little electric. Hes WAY better than I am.
The one with a half a wing can do that because the airplane was designed for that specified thing. I ripped my wing off on my F6, there goes $2,000. I almost save a small T-6 once when the wing blew off after doing rolling circles, didn't pull the throttle fast enough to pull it level and destroyed the bottom of the airplane.
The B-29 I happen to know that guy personally, and he is coming down in March to out R/C event. He is totally and expert pilot, other than hes crashed 5 of them doing that.
Here is a flier if you guys want to come down and watch him fly:
