I actually have one of those older articulating arm stands that he mentions in the beginning of the video. They were made for the older larger gas heli's and worked quite well. They actually had more motion for the heli, and you could actually fly 360 degrees around the center point.
They wouldn't work for a small electrics as shown since they would be a bit heavy for the heli to lift. The one I have was given to me from the estate of one of my late modeling friends. it was destined for the trash heap, since no one wanted it. I was going to dismantle it for the aluminum stock, but never did.
