Get a Hobbyzone Super Cub RTF for days when you can't fly the Ultra Stik on the buddy box. It's designed specifically for folks to teach themselves how to fly. The Spitfire wouldn't be easy to fly on your own. The Parkzone Slo-V would be another good choice, but it won't handle much wind.

A 4-channel glow trainer wouldn't be any easier than the Ultra Stik to fly without help.
