The Super Sportster is a fine intro to low wing planes. Set it up on low rates, it will be easy to get used to. Then you can crank up the rates and learn some aerobatics. One of my students got one, it serves him nicely.

I will, however, recommend you really wring that first plane out, 200 flights or more, before moving on to something like that Sportster. You can do inverted flight, and all kinds of aerobatics, with whatever you are using for a trainer.

Good luck,
