I flew mine once today, huge winds, but that brings me up to 18 flights. No dead sticks, huge power with the Vess 17-6, dare I try a 18-6? It is really fast now, I hate to try a 10 or 12 pitch prop. I really don't think Ultra Sticks are supposed to go this fast. It was cold, about 50F, so the lift and power was very impressive today.
