Firstly can I say I can't fly anything including an RC toy so feel free to shoot my comments down in flames. Autorotation is only good if you have a power out and not much use in a tail rotor failure. I have seen the film of the channel 4 news helicopter crash in Brooklin that lost the tail rotor, and that only took about twenty seconds to crash and that was spinning wildly. I think if that is what happened here the Pilot was just along for the ride and saying he could have picked a better spot to land in nonsense.
