Hi,
You can do loops, rolls, inverted, stall turns, outside loops, cuban 8's, split S, immelman turn, etc.
Basically a trainer fitted with ailerons and with moderate power can do all of the above moves.
The only difference is that a trainer will not be able to do some of the moves as well/accurately as aerobatic machines.
Be careful to make sure your wing is well mounted. If you pull too much negative G a wing poorly mounted or fitted with bands may well come off. Just be careful not to pull to much when flying aerobatics with a trainer.
