IF you are starting to do a few minor aerobatics, I would suguest looking for another plane to advance to. Your trainer although being able to do minor manuvers, will limited your progression into better flying. Keep flying it and learning the hammerheads, loops (outer and inner) and other basic flying. ALso learn to fly with rudder only. That is something that will help you later on. Increase your throws on your control surfaces may help your plane be more aerobatic as well as taking out the dihedral. When you become proficent in these areas, you'll be ready for more a more advance airframe. SOme of which are not possible with the trainer design.
