I really do not want to seem negative about this but I have been burned plenty of times buying off sites like E-bay. While I have never purchased anything off RCU there should be some clause about members not doing good business. Sometimes all you can do is write a bad review about the guy and hope others will learn from your experience, but since he is getting out of the hobby I don't think he really cares. I would call the guy and leave a message. You may have a limited time frame to where you can do something about your situation. So if the guy does not call you back within a day maybe 2 contact RCU and see if they can help you. There may be other legal things you can do ,but I would start by calling. If the guy does answer tell him that you have not recieved the merchandise and ask for a tracking number. If he says he did not ship it out yet, I would basically tell him to get off his butt and get it sent otherwise threaten him with legal action. I am not sure about using money orders since I use a credit card and I would advise you to get one and a paypal account. If the guy does not do any of these I would be suspicious of him and not buy from him. Credit cards and a Pay Pal account keeps you from getting burned like I have in the past and it gives you an OUT (as the saying goes) just in case of these situations. You might be able to call the police, but I would not waste my breath on them because they may treat it as stolen property and file it away somewhere for statistical information.
