If you can spend some more I would recommend the Apprentice or the Sensi . The Super Cub in my and others opinons is not a great trainer and won't be a plane that will stick with you as you gain more experience. If it survives it will more than likely get tossed aside once you master it.

Also find someone experienced to go over the plane, take it up , trim it out and help you to learn to fly it as opposed to going it on your own. You will be further ahead in the long run and won't get as frustrated.
