I guess all inputs welcome is really not the case huh? You said it in your first post. The planes in my hangar are just that, in my hangar. Ones used for teaching to fly and such. Aquired from different people.
Since you only want to hear what you believe, that is a great airplane- none better. You wont have any surface problems at all. The YS .63 will be perfect also. A 13x4w prop is what they like best with YS 20/20. For the price you paid at least there wont be any heartbreak after it disentegrates.
