Yep...as a pilot and mechanic who is always going to airshows no one at present does this in a full size...just don't quite have the power to weight....some can almost hang on the prop in a slow knife edge...but not stationary...also in a full size if the engine were to burp you'd be dead. With an R/C...you just pick up the pieces and go home and glue them back together...;o)

I’ve seen this at airshows, with a full size real plane with pilot, and as I said above, I’ve seen this go into a climb then a hammerhead to get out of it.
