Don't take this the wrong way, but I've been chided for doing something like that at one RC airfield. Even though I didn't exactly appreciate the lecture at the time and thought I was just trying to help, I have to agree it's a safety no-no. Even if you have a $85 carbon prop, it's not worth sending somebody to the emergency room. Taxi it onto tall grass or nose it into the ground would have been the prudent thing to do.
Otherwise, great vid production.
