If you want something with ailerons, you could also look at the Begin-Air from Park Flyers R/C:

The Hobbyzone Super Cub RTF package is more widely distributed. You should be able to find the Super Cub RTF at your local hobby store, and they will normally have spare parts like propellers, wings, tail assemblies, and extra batteries as well:

If you decide on the Begin-Air instead, you'll have to mail-order spare parts. Waiting a week or two for that new tail assembly that you need can prove frustrating during nice spring or summer weather when you're dying to be out flying but you can't.
