Update on the Lil Duper Zilch.
Well I have been making progress on the Lil Duper Zilch and I am breaking in the engine I finally settled on. The PAW .19 is starting to show life as it continues to break in. With a 10x4 wood prop I can peak it at just over 9K, but for the most part I am running it at 8700 RPM which is still 500 revs better than when I started.
If you look at the wing you can see the yellowing of the leading edge, that's the only part from the kit I chose to use. I think if I had it to do over again I would have made a new leading edge. This kit sat in some attic for many years. The wood can best be described as horrible, and the fit of the parts is even worst. As for the plans well, if not for the plans I would have spent a long time figuring how this plane went together. Thank you Barry Baxter! I really don't know how Berkeley stayed in business as long as it did.
