a friend of mine has one with a Saito 72 on it. I flew it the other day. Nothing short of awesome. We flew it with a 13x6 prop and it would lock into a hover about half throttle and pull out with plenty of authority. We decided to try a 14x4 prop on it. You would not beleive the difference.The plane was all over the sky and neither one of us could hover it.The plane felt like crap.Switched back to the 13x6 and you could hover out a tank of fuel with ease.Go figger!
