To my understanding and not just limited to this area/hobby but others as well since I'm into flying rc heli's , rc cars etc... a great deal of duplicating occurs in China without consequences because China doesn't have a copyright law nor do they recognize any from foreign lands as well. It's just the nature of the beast.

It's the land of the clones....

However it really doesn't matter here all what does matter is how they handle their business to our hobby, and CT I found to be nothing short of professional in every aspect.
