RE: First Plane! Which between the two
The Super Cub is much better suited to learn to fly with. It was designed from the ground up for new pilots who are trying to teach themselves to fly.
I originally started out with the Aerobird Challenger, and was quite frustrated with it. Some folks like the Aerobird, but I found it difficult to keep trimmed out and flying straight and I spent a lot of time pounding mine into the ground. By the time I figured out how to fly it, it was pretty much totalled.
