RE: Next plane / First plane
I have the Advance. It is a nice flying plane, but it's stall speed is quite a bit higher than that of a typical high wing trainer.
I think you would want to be to the point where you can consistently make smooth and soft landings with a high wing plane before you try the Advance.
For a high wing trainer I have the Apprentice. It flies very well and does inverted and basic aerobatics very well for a high wing foam plane. It is also tough, and easy to repair, with parts available at a good price.
I still enjoy taking mine out and shooting landings. With seaplane supply kit, it also makes a good float plane.
Anyway, I guess what I'm suggesting is consider getting a trainer type plane. When you are to the point where you are comfortable with 3D capable sport planes, you may find that doesn't mean you won't still have fun flying the trainer.
