Good advive from FM. I did some hour building there and it was amazing. Trips to the coast were excellent and real hour builders. You would have to either get an SA PPL or get your JAA one validated, which should only take a couple of hours and a trip to pretoria. Be careful to allow for this though - I saw some people arrive not knowing this and only giving themselves enough time for their intended purpose, therefore leaving without everything done. I have a feeling that 43 don't accept hour builders as they are too busy but I prepare to be corrected on that. CFA are a good bunch and very cheap. A grumman was there for about £45 an hour. The other airplanes they only allowed you a few slots at a time in although there is a Katana too for building if your brave!
Enjoy!
