You officially need a study permit to attend any school in SA. However ...
Unofficially you can get away with a tourist permit. Valid for 3 months but if you ask for 6 months they will usually give it to you if you have enough funds to support yourself.
If you are only planning on a few months' training don't bother with a study permit. You are simply on holiday and decide whilst you are there to do some flying !!
