Just got back from Beijing and Thailand had no problems with my Mavic. Never registered it for Thailand. I Made sure when going thought customs I pulled all my Batteries out and sent them though the scanners, and all was ok. They pulled them out and looked at them in Beijing but never said a word. Biggest problem was finding a place to fly them away from people. If you find a place (And is hard do, if you don't know the area) all is ok just like Vancouver where I live. I had fill out the paper work in case I had trouble, but never needed it. Just be careful where you fly and all should be good.
