Try #2! I'm the proud owner of a "gently" used Phantom via eBay. On my first flight one of the propellers fell off due to a loose nut and subsequently crashed inverted onto my garage. After I brought the Phantom back into the house I noticed a sliver of metal sticking out from one of the motors. I was able to remove what looks like a "C-clip". Since then I have made 3 more flights which were uneventful. Am I pushing my luck and have avoided catastrophic failure of the motor since then? Should I replace the motor or try and reattach the C-clip (and how)? Thanks.
