Sorry about the picture quality but I have all but worn out this part of the old VHS tape.
The rolling elements at the start of this flight set the standard (for me) of smooth, precise flying. I spent hours rolling from end to end and kicking the knife edges with my Curare.
I'd almost give my left whatzit for a plan.
