Nope, that is not possible..........The only flying Cheetah in the country is "Bandit" and it belongs to Denel, and it looks like this
12 Other Cheetahs have been sold to Ecuador, and most of them are already there.
It could be that you saw one being tested for Ecuador, but I doubt if it was choc brown.
All Cheetahs being tested here for Ecuador are flown in the SAAF colors.......Diamond, Low visibility scheme. They are only being repainted in Ecuador.
Maybe someone bought one...................but I doubt it very strongly. Cause a Cheetah is one expensive bird.....both fuel and man hours.
