Not just the Chinese who do that. Viet Nam has a couple of model boat building firms, doing fully built models, and most of their range are copies from ALL the European kit manufacturers. Don't really know how they do them for the price they offer to Tourists in Ho Chi Minh, and some of then are well done. Some not so well. Not trying to say its right or ethical, but if living in that country would make a good start for anyone wanting r/c boats as balsa, hobby shops and kits as we know them are totally non-existant. They have been doing it for years, and do export, mainly to the US
