Big Trainers
I would say that while a Cub is a great choice, I would definitely clip the wings. A scale cub wing was great for the original full size version where a lot of wing was needed to compensate for a small engine, but that big wing (IMHO) doesn't work well on a model. It's too much wing for that plane, whereas, the clipped wing version still floats like a dream, but also let's you have some fun with the plane. It also removes the full size wing's bad tendency of creating adverse yaw.
