Query: Broke after one flight

This cheaply made and assembled chopper ( I have three other choppers from a different company that are great, BTW) took more time than necessary to setup because of faulty threading on the battery door on the RC. Once it was finally ready for flight, I flew it once then the gear teeth wore away. Literally on the first flight the gears stopped gripping the rotor spinner.I would never buy from this company again.
