Interesting. I'd like to see the SolidWorks and FEA on that crank, I
bet the webs and bearings get awful narrow when you go and double the
number of big ends strung along it.

Also, is there any credible evidence that this little motor actyally
does put out 130hp for any appreciable amount of time?

Having developed and raced tiny Formula IV road bikes, I came to
appreciate that the devil is in the details. And the more details you
have, the greater the opportunity for bedevilment.

The more I study airplane engines and their operating environment, the
more I come to appreciate the underrecognized genius of the big,
simple, slow-turning flat fours that came out of the 1930s. Parts you
leave on the ground will never break in flight.

Thanks again, Bob K.
