A Cub ( or4 Cup as they are sometimes called in MA) is a fantastic plane. It can be as gentile as a trainer or with a clipped wing as aggresive as Super Decathalon. I've had the GP Cub ARF (81") I powered it with a Tower Hobbies .40 size engine and it flew very scale like.

The rudder is your best friend on a cub. Learn the rudder. learn to hold UP elevator during the start of your take off roll to pin the tail to the ground, and then let it off slowly until the tail is flying, the add it again and you will be off the ground. It is a beatutiful thing to fly a Cub.
