A lot of us with fanatical tendacies build all our engines to aircraft standards, minus all the safety wire.Called "BluePrinting!"

 

Yea, 6 cylinders on a crankshaft is bound to be smoother than 2, and then there's the 360's 2 crankshaft dampers.

 

Put some V&H straight shots and he could really **** off the neighbors.

 

I knew I had a photo of the one at Oshkosh! I really dig the "Reduction Gear" method of controlling rpm's. :-)

 

Big clanking ***** required to get in the cockpit of this one. People though I was nuts for riding my old Flathead to the 100th celebration in Milwaukee.

 

I can't tell from your pictures, but was there a hole cut in the seat for the pilot's *****?

 

A six-cylinder horizontally opposed motor (known as a "boxer") is pretty dynamically unbalanced and vibrates quite a bit. General aviation piston engine aircraft, Porsches, and some Suburus run this configuration. Porsche actually utilizes a counter balance in order to dampen the vibration, and they had a motor that was an option on certain Mooneys, which are pretty high-performance GA aircraft, for a few years. A 45-degree v-twin is probably not much better or worse than that from a vibration viewpoint. My only thought is that's a pretty heavy motor for the amount of horsepower and RPMs you can get out of it and, it's got a pretty big frontal area mounted in that configuration, as opposed to other powerplants available out there.

 

My understanding is there was. In addition, the fuselage had a hole as well in anticipation of using the plane on a carrier. The plan was to use his ***** to catch the arresting wire.
