Also, are you comfortable with your trainer, or are you about to pop the rubber bands because you are doing loops, flying inverted and seemingly trying to get that poor plane to knife edge, even though you know that it will not.....if so then it is time to move up...BUT, if not ANY PLANE you move up to will not act like a trainer..I know of none that is JUST above a trainer in flying behaivor.. trainer has lots of dihedriel and a flat bottom wing. those 2 features at one time will dissapear with any plane you get... GOOD LUCK AND HAVE FUN
