Philippines is not a real good place to build time. Aircraft rental prices, fuel costs, atc costs all are high. Plus very few places you can get fuel away from the major training centers. Also to fly alone I believe you need to do a licience conversion. Cost for a C172 is approx $215 an hour. You want to build time go to the western US. You can still rent a C172 for under a $100 wet and have hundreds of airports to choose from.
