Thanks Ron!
I have many of those reviews in my rather extensive magazine collection. It is MUCH to finad and read the reviews online. My dad recently passed away and he was a modeler who had an interesting collection of engines which include a NIB Ross twin which still has the original $125 price tag on it. He also had a techno power radial and a couple of OS wankels. We ran the radial - very cool and flew one of the Wankels which were amazingly smooth and quiet.
