"Sek Kong" is the Hong Kong Aviation Club, based at Kai Tak. Helicopters are flown out of Kai Tak and fixed wing out of Sek Kong at weekends only. You need to join the club, which is HK$30,000 down and around a thousand a month. Rates are around HK$2800 for the cessna 182 last time I looked, R22 about the same. You can fly on a foreign licence, or your HK CPL/ATPL.
They have a basic web site you can google.
In the Philippines I hear that the Angeles City flying club is up for sale, and as long as the buyer runs it as a going concern the price will be very reasonable. They have microlights, which are the coolest thing to fly when the temp and dew point are above 30C!
FWIW
