I've been flying all over the Philippines for about a month now. Absolutely no problem, except for launching from certain private property, aka, hotel grounds. Hotels are really freaked out by drones for some reason. I launch from parking lots, from McDonalds lawns, pretty much anywhere I can find that has a clear reach of sky. Went to Taal Volcano today, and all I did was ask the guide if I could fly, and she helped me find good launch sites. Was all over Palawan a while back, and the boat drivers, guides and tour reps all were more than helpful with getting my done in the air. However, it's now so drone friendly that I actually run into drone congestion! Jumped off a boat at a beach one day and had three DJI drones hovering overhead when I hit the sand. NOTE: Seven Commando Beach near El Nido seems to have some kind of drone jammer in operation. I tried to fly my Mavic Pro and the Go 4 app kept disconnecting. I talked with several other DJI pilots there and everyone was having the same problem, so it wasn't just me. Otherwise, flying in the Philippines is clear sailing. Enjoy!
P.S., the Philippines has some of the MOST spectacular scenery for photo and video capture that I have ever encountered. Absolutely fantastic!
