RE: Matt Chapman cap 580 .40 size
I know it is quite a bit heavier than the engines mentioned in this post but does anyone know if a Zenoah 20cc will fit in the cowl. The specs on the Zenoah says it is the only gasser that will fit the 60 size cowls. I have ordered the plane but I am still deciding on my engine choice. If the Zenoah won't work I'll go with the YS 63s.
