The Mini Ultra Stick is on Horizon as well. It will be perfect for what you are wanting in a plane. Of the ones you mentioned, the Apprentice is a trainer, so if you want something you can let go of the sticks and have it self-correct that will work. The Yak is a serious aerobatic plane which you're probably not ready for. The T28 is nice as we've said, and you probably can answer for yourself if you want another Cub. But the stick is one of the easiest flying sport plane designs ever made, and has been the step up plane for no telling how many RC pilots who were ready to work on learning aerobatic maneuvers and improving their flying precision.
