from what i've been told, the pga is a very conservative, very careful organization and I'd be surprised if they have already embraced multi-rotor technology beyond satisfying their basic curiosities. having said that, i've also been told that they shut down the courses and clear everyone out on the day that the heli's are brought in to do the aerial work. all full scale stuff from what I understand.
maybe i'm wrong though but i saw the same footage you're talking about and it looked full scale to me, imho.
