I have just had a similar experience, where I bought a kit supposedly nib complete with plans. When it arrived the box suspiciously light and when I opened it the was no cowl, no canopy, no h'ware, some wing ribs missing, some fromers missing and no sheet or sticks. the plkans that wee in there were only a line drawn 3 view. I called the turkey and he said the kit had never been opened and everything was in there when he checked and he then hung up, and he never answered any more calls. I was lucky I paid with paypal, and will get my money back. I also contacted the seller an told him to arrange return of his junk himself. I guess I have been lucky so far on both ebay and rcu, only 2 deals in 2 yrs go bad so far. I guess its only a matter of time before any of us getting bitten, and in these troubled times its going to happen more sadly enough, Comunication can only help so far, if a clown is going to try to scam you he will no matter how much you talk. Its why I prefer to only use paypal if at all possible
