BTW and FWIW, if 92b would continue to read the Godbold book, he’d learn about buckling loads and why pushrod flex isn’t the issue when checking this stuff.
My post is a direct quote from his book. If you believe that information to be incorrect I'm curious, what part you disagree with?
When you say " checking this stuff" I'm guessing we are still talking about checking undeflected and deflected lift measured as outlined in his book and that we haven't moved on to another subject?
