Based at Fisantekraal - less than 5 mins flying from the General Flying area - pretty quiet and you dont have the hassle of getting in and out of Cape Town Int'l airport - nowadays with all the work going on it takes longer to get into the airport than it does to get airborne!!!
They have a good reputation and are only 30 mins by road from Som West.
They do bring u across to FACT to fly there in the quieter periods (which are getting less and less nowadys). Some hours we are getting over 45 movs and hour in the CTR, so you are just going to be wasting your precious time if you wanna fly in and out of there.
Think there is also a flying club at FAWC but not too sure of the details.
