I just ordered a UCD 3D 60 size for winter flying. I fly giant scale 3D planes and wanted to keep my thumbs tuned through winter (4-5 months) . I have an OS 120 FS I will use on the UCD 3D 60 and wanted to know if any one used this plane/engine combo and how well it flew? I have seen guys using the YS 140DZ which weighs a few oz more than the OS 120 FS, but they did not say how well it 3Deed. Can the Ys 140DZ set up guys post their views as well.
