If you intend to fly a drone in Thailand, whether as a hobby or for commercial reasons, you have to by law register your drone first. If you don’t you could face a fine of up to 100,000 Baht or even up to five years in prison. They are serious about this, so before you fly, make sure you register your drone with the National Broadcasting and Telecommunications Commission (NBTC). In addition, if your drone weighs over two kilos and/or you plan to use it for commercial reasons, then you need to obtain insurance and get permission to fly from the Civil Aviation Authority of Thailand (CAAT). Their fine for not doing this is up to 40,000 Baht and up to one year in prison. Before you ask, if you have a toy drone, for example weighing less than 250g, then the NBTC or CAAT are not interested.
