Barry, I finished the ultra stick 120 yesterday. I got several flights before the wind got up. The thing flies great, but the 110 is not near enought for this plane. Vertical is very limited but does a pretty good job of basic pattern stuff. The 110 is still really rich. It only had 4 previous flights on it prior to yesterday. Thanks for the info on the YS web site. It was a big help. I am planning to shed a little more wieght and lean on the engine a little more. I think this will help the performance.
