Here's why I think it's a R/C model (And ALL of this is just my unqualified opinion, so don't beat me up...!)
•The white exhaust
smoke doesn't seem typical for a full size stunt plane:
If it was purposely trailing smoke, he purposely shuts it off at the top of his Hammerhead turn. It seems like the few times I've seen that in person, the smoke is on at the top of the turn to leave a little "cloud" up there.
If the smoke wasn't on purpose, why would a highly specialized stunt plane be flying around with an engine
that needs rings? Seems more likely that an R/C plane would be smoking.
•The wing comes off at the top of the turn, which is performed at 20-30 kts. in a full size plane with very little stress on the wing at that point. Seems more likely that mechanical fasteners on an R/C had been vibrating loose for some time, and the last one let go at the top of the turn.
•Wing comes off in a very clean break. No debris, pieces of aluminum
skin, etc. seen when it comes apart.

in their wings) and engine
•When it lands, it bounces faster (less mass) that I would expect for a full size plane.
•When the plane rolls to a stop, it turns to the left, conveniently hiding any trace of a broken right wing stub.
•To me, the voices sound dubbed in after the fact.
•But the biggest deal breaker is, if this were real and you had just captured the most amazing landing ever, would you shut the camera
off where this video ends, or would you run to the plane and keep filming, especially capturing the pilot and the broken wing stub?
Just like the UFO video from Brazil(?) that was going around the internet
a few months ago (and was later acknowledged as being fake), I'm sure the truth will float to the surface soon...
