This is where I say (again) that my favorite aircraft engine of all time is the Junkers Jumo 205... a 6 cylinder, 12 piston, 2 stroke, supercharged, dual crankshaft opposed-piston aircraft diesel.

No valves, no head gaskets, gear-driven timing, weighed 1300lbs and made 870hp - in the 40s. The accessories were all run off the slave crankshaft which had the added benefit of significantly reducing the power the timing gears had to handle.

I am unreasonably fanboyish about this engine design :swoon:

Christ that sounds like the most German engine ever. There is a BMW engineer with a cutaway of this engine hung on his wall with the caption "Perfection" or some bullshit.

*sniff* It's beautiful! Perfect, even.

Anyway, I'd love to see more and more aero diesels start powering the GA fleet. Avgas is dead and anyone seriously thinking of dropping 25-30k on a shiny new big bore flat six without looking at some kind of re-engine program is being incredibly short-sighted.

whoa whoa whoa. PLEASE tell me this isn't something that needs doing often. Swear to god if that gutless 5-cylinder boat anchor costs me any more money. :argh:
