vsv123 Here's the story on the MK-17 glo. I got this engine from Stu Richmond who made several trips to Europe and he assured me this was a factory engine and there were more than just this one. Stu explained how these engines were built in schools and could vary in quality, depending on which school.

As far as Russians not using glo engines they were quite active in FAI speed and FF competitions in the 50's, 60's and later. They made many .15 glo engines; usually copies of various Supertigre .15's and later on they copied the Rossi .15. A few I can recall were made by Uckam, Vip, Kometa and the Russian Meteor. Stu showed me several Rossi copies but some had no names on the case. They did look extremely well finished.
