There are different type of aerobatic maneuvers depends on what type of aircraft you are flying. You may perform maneuvers with a trainer airplane for instance you could practice stall turns, loops, or in scale you could practice powerdives, stallturn, rolls, loops, cubaneights, immelman's etc. But always remember the positive and negative g's that can break your plane apart. So I strongly recomend you to find an experienced fellow modeller on your flying site to help you out with these.
