i'm training on a superstar 40. really easy assembly, nice looking and well built plane, and you won't get any complaints from me about how it flies. It's easy to fly, and it'll cut up pretty nice (i think so, anyways). I'm not moving up from it for a long long time at least not until i can fly it in my sleep!
Only complaint i have is it takes some effort to pull off an aileron roll. I still havent gotten it to pull one off that looks good yet..But the nice part is the plane recovers almost instantly..
