It depends what you want to do ... 3D? Scale flying? or just messing about. For me you can try the Black Horse Extra 300 60 if you want a bigger plane that flies nice but does not cost much, don't expect her to really do any 3D. The Fliton Extra 330 is superb if you match it with a SA82 and awesome with a SA100. The Pacific Aeromodels Edge 540 (90) is a nice plane to fly and their Laser 200 (72") is one of my favourites. Let's not forget the WM Super Chipmunk 90 for a little nostalgia, that is a very nice aerobatic plane to fly. It feels really solid.

Question is what do you really want out of the new plane?
