Bulletproof is relative. Kevlar may stop small arms fire but isn't worth a
damn against a 155 Howitzer. As far as experiment aircraft engines are
concerned and automotive conversions in particular the Corvair is probably
as close to bulletproof as you're going to get with the minor exception of

I would think that harmonic RPM could "almost" be eliminated as a cause
except in combination with a prop extention or out of balance prop/ spinner
ect.. Simply because the crank problems only started when they were put in
KRs. I would suspect that the same harmonic ranges that would be of conce

I do not want to sound out of line, and I am obviously not privy to all the
information gathered at the testing site.
However, I find it alittle pre-mature to declare all non-nitrided cranks as
having a problem simply because the only example of that did not have a crack
in it.

Mark, well said. From my engineering days, I was so frustrated by
Product Assurance types that always wanted to wait for more databefore
accepting the obvious.. Our "experimental " category is supposed to be
a learning process, using past good practices wherever possible.
