in a real helicopter.

I would have thought that this video has already been posted on here but just in case:

It has, and no doubt it will be posted again in the future

I'm pretty sure that pilot is Charlie Zimmerman, there are some great vids of him chucking that Bo105 about on the net

Awesome to watch, never seen that vid before.

Would love to see on-board footage!

Enjoyed that, looks like slow motion when compared to RC 3D

You have got to have some balls to do that!!

Would the heli have negative pitch or just the momentum keeps it in the air?

Yes all full size helicopters have negative pitch as this is what brings them down whilst maintaining a constant rotor head speed
