RE: intermediate or not?
Cubs are easy to fly particularly in the larger sizes. But all Cubs are a little more difficult to fly WELL. Like Wayne said you must know how to use the rudder & not just on takeoff & landing.
Being a larger model it will be gentler & more tolerant of mistakes but big models do not bounce when they hit the ground, they break. You must know how to takeoff & land properly. If so it will become your best friend. - John.
