I'm no expert on Cub's or scale building, but I bought the GP 60 size. Clipped wing version to 83" (I think). Good quality but still requires building/covering skill. I have OS .91 Surpass and it flies great. A little squirrelly on the ground, but I am told full scale Cubs were famous for ground looping.

Flying requires coordinated rudder turn--it is very sensitive to rudder input. I am getting pretty comfortable with it, but last week during a series of take-off/landings, I panicked when it veered toward me on take off and put it in from about 5'. Minor damage.

Good luck with your Cub.
