RE: eBay issure
Your only option is the one I gave you. I understand you don't want to send the car back, and as I said, hopefully that won't be necessary.
You can file a dispute with paypal relating to the description, but if he didn't specifically mention the servos in the auction description, then you are out of luck. I have posted stuff on ebay before with pictures showing all kinds of other RC equipment in the shot, which are unrelated to the auction. I would have laughed if someone had said to me 'I saw a multiplex rhino (a $100 servo in europe) in one of the pictures, send it to me'.
Since the auction is ended you can post a link to it. Maybe that will help us advise you.
