I hade a deal with King a few months ago, I traded my GJC "Skyray" for a Tamjets Rafale and RAM 1000. I looked over the Rafale, it appeared to be in pretty good shape, but I did find out that the fuel tanks leaked, but I don't think King would have known that. He ran the engine, and it ran just fine, but I got a message from a friend that he looked at the same engine, saw it run, but thought that it wasn't putting out enough RPM to be a RAM 1000, but maybe a RAM 750. King stated that the fuel line came off the pressure fitting and the engine didn't get up to full power. I asked him (King) if it was a 750 or 1000, he assured me it was a 1000, and could verify that by pulling off the front cover and looking for the etching. I am going to run the engine again, but I am not expecting any problems.....if I do I'm sure I'll post something.
