You are going to love that Balsa Usa Cub. I have that plane myself in the Super Cub version, 110" wing span with a .91 Magnum FS and it flies very scale.

I'm a Cub fan myself, though my collection is not as thick as yours yet, I also have a 72" Arf J-3 with a .46 ax that is about to go on floats, a 96" Sig with an Asp .61, and several electrics including a few Hz Super cubs and Parkzone J-3's. I would like to add that Hangar 9 cub and the Goldberg Cub to my collection, probably won't be in next few months though unless I run across a real steal on one of them.
