As far as Quique and friends, I thought that was just due to the inertia of a large plane. I saw a pilot flying a 1/4 H9 Cap that went over very fast. He did it shortly after take off, and it looked really good right over the threshold of the runway. I've never had a plane, including a couple of fun flys, that went over that fast. I guess his CG was back near his tail wheel. I'd guess my Ultimate takes 3 seconds at 45 degrees of throw. Maybe my CG needs to go back some more.
