I have a Wingo which is the same three channel set up. In addition to barrel roles, you should be able to manage stall turns and wing overs. I have on occasion managed a few seconds of inverted flight. Depending on the wing, you may be able to manage some mile spins as well.

If your new at all this, you should definately get someone to help you when you first try them. Also, if this is a park flier that is not designed to be aerobatic (like my Wingo), you will need to make sure you don't stress the air frame beyond it's design limitations.
Don't ask me how I know
Have fun!
