The Super Cub and EasyStar both have a very good reputation as easy to fly planes and there is nothing wrong with learning to fly on rudder/elevator (that is what I learned to fly on). But tiring of them depends on the pilot and their attitude. I still enjoy taking a 2- or 3-channel plane out to the field and to some lazy, relaxing flying just for the heck of it just as much as I like to fly pattern or practice Quickie pylon. I've never tired of rudder/elevator flight and treat it as another aspect of RC flight to be enjoyed (3-channel aerobatics is a real challenge to fly too that many pilots don't have the skill to do). For me, I'll enjoy flying planes just because they fly, regardless of what they are.

Another option seldom mention is a powered glider if you absolutely have to teach yourself to fly. They are very gentle giving you a lot of time to react and learn what the plane is doing. This will give you the basics on flying and allow you to step up to a faster plane with out a lot of problem.
