I saw the smaller yak do a demo this weekend. The airplane was flown by Chris himself at a flyin here in GA. I never got a chance to go over and talk to him but the plane sure looked good and did some amazing stuff. I had seen most of the stuff he did in the movie on the website but he also added this funky super high speed mind blowing tumble. He went from full throttle on a horizontal line into a tumble which quickly became a blur and then flew out of it like he had never left the orginal flight path. Made me wish that I didnt already have too many irons in the fire b/c I would have been grabbing this thing up as soon as it came out.
