John, Respectfully submitted, but isn't that obvious? A design does no good that sits on a shelf. I am reminded of General George Patton, "A good plan today is better than a perfect plan tomorrow."

No engineering is ever complete until it is field tested. IMHO JohnD

Ed,
That is just the way it is in engineering. It is always easier to do it better the second time! There was a sign on the wall of one of the places I worked, I learned the meaning of later. "The trouble with doing everything right the first time is that people don't understand how hard that actually was!"

I agree with your weight assessment, Bill. Pay attention to every ounce as they quickly add up into pounds. I figure I could remove approx 15-20 lbs of weight if I redid my FWF again from scratch based on lessons learned. Its easier to keep the weight down than to remove it later {:>)

How does the flying weight compare on the 20B with a lyco 360 for example?
Thanks,
Bob
Bob, Mistral is listing the weight of the 20B conversion at 395 with radiators I believe. The 20B will produce IO 540 like HP though. The 13B done well can make almost 200HP without even P-porting. Most 13B's so far are about the same weight as a 360 with all the plumbing. Carefully setup the 13B NA engine shoould be lighter than a O-360, you just need to do a carefull engineering job.
