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, 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.
