You know I always tease you guys that enjoy collecting, like, Arrrr, if I had that, I'd run it. Get it all hot and greasy and scuff it all up... But I really believe that's one engine that I would put under glass. I can't promise it wouldn't eat at me until I devised a way to somehow mount and fly it once without getting any evidentiary marks on it, but then i'd put it back under glass.

Now answer me this; other than being part of the one last factory run which wasn't even fully completed, and the NFFS number and certificate, and being solely for members of the National Free Flight Society, is there anything different about this Medallion than its last mass produced sibling?

The slits on the exhaust ports are different. One is slightly wider than the other. Also if I remember correctly the bypass flutes both have boosts. I forget if it's one or two boosts total. It makes it hard to fake. Plus you get a really neat letter of introduction. LOL

That thread is pretty old and it was getting heated which is why it was locked.

Long story short, There were more cylinders made, but not distributed through regular channels. There have been some engines put together with these spare parts.

Without the serial number, box, letter. The value is the same as any other Medallion, perhaps less as it’s not a factory assembled engine. I would just use it for your next project and enjoy it.

The piston should have one ring on the skirt, the exhaust slits should be the same size (the above post is not correct about exhaust slits). I don't think the cylinder was tapered. Two intake ports each with one boost flute. The Killer Bee .051 cylinder, piston is very close but the piston has two rings on skirt and the lower exhaust slit is slightly larger than top one. Seems like KB .051 piston was tapered and lightened but a little foggy on that. OK flame on!!


A link the man that had em made. Reading that leads me to think no SPI also.
