As I looked at buying overseas myself, this is what I found about UAV's. It seems when units are imported they are checked for regulatory compliance in the country in which they are sold. For example, in the US it's the FAA regulations they have to comply with. They generally have a sticker on the TX showing its been done. Here in Oz it's CASA. If I buy here and have any sort of problem with a crash and subsequent damage to property, the first thing they check is if the unit is compliant.... With CASA approved its called a "C tick" sticker. If you bought it overseas, and imported it personally, you then have to prove personally that the Chinese, German or whatever, compliance details are acceptable in your own country. Don't get me wrong, what's acceptable in one country maybe OK in another, it's just that the onus is on you as the "importer" to prove it. That, I would imagine, involve the legal fraternity somewhere along the line, and that to me spells money. Just pointing out that what appears a cheaper or faster alternative, may not be worth it. These are the rules as far as I can ascertain, but it would be a good idea to check out your own situation.
