RE: which RTF plane???
I vote for the Super Cub. The aerobird would probably be fine but the cub looks more like a full size plane. While you are crashing and rebuilding the cub (you will crash, we all crash) as you learn to fly you can be saving up for the WWII planes.
Finding a local pilot to help you will shorten the learning curve and save you money (and time) spent on repairs.
