You have a 110 listed in your poll The plane calls for a Max of 82 in four stroke,,, looking at it's stated wieght of 6.4 - 7.5 lbs min. I know it's not going to do any on the deck 3d with a 82.. And a heavier engine will kill it's wing loading. If your looking for a hoverbatic plane I would guess this is not going to be it. But if you have your mind stuck on this plane I would nix the YS and go for the lighter Saito 100.
