Ya know..... sometimes it's better to just cut your losses and move on. I have had similar experiences with Chinese crap from ebay and got no help in resolving problems going thru ebay. The last time, I received motors that were boxed wrong. Correct part # on the box, wrong motor in the box. My response from the chinese co. and from ebay was virtually word for word what quadcopter102 got. I took the motors, which turned out to be junk anyway, and broke them with a hammer and emailed the picture to ebay. Now I only buy from ebay if no one else has it. I sold all the rest of the chinese junk, that I intially bought when I got into this hobby, for the cost of shipping only.
Take your x8 and use the parts to build something fun. There are an astonishing # of sites devoted to modifying Syma products. Buying quality is more than just the parts. A big part of it is the supplier and the service they provide. We in the US "colonies" have a large variety of quality suppliers to choose from that provide real, not copies, of parts from all over the world. I know other countries are somewhat limited but there are good suppliers the world over. Just do your research and get back to having fun!
