Lucky no prop hit. The one guy was trying to grab the other. That is why he failed to get out of the way in time. Very amateur RC pilots or a failure in controls.
Agreed. Kind of looks like one of the engines was out, which makes for a difficult landing. I'm almost sure that the right engine is out. Most R/C pilots would kill the remaining engine and land dead stick instead.
Aside from that, landing with the plane coming straight at you like that is just stupid.
