how about this then, a BIG rc helicopter "upgrade" company, very well know if you are into that sort of thing, recently had problems with main rotor blades, they where snapping at the root, where it connects to the head on the helicopter. I had a set, luckily didnt use them. The type of helicopter they are used on I am told has rotor tip speeds in excess of 100mph, then the blades fly off. THey replaced without question new designed blades, but the old ones are STILL for sale through vendors on ebay etc, how bad is that >:(
China can certainly make the goods cheap, but quality control is another thing. I am desperate for a esc that can handle 16cells, and the chioce is very limited, but I refuse to buy from china via ebay for this reason, and I always try when possible to support uk model shops, pity virtually everything to do with opur hobby electronics is from the land of the rising sun :(
