Even more crispy, even more better. Cox 140

That's a "Rhino" 140. A Cox gasoline Roper/Beaver 140 engine that was converted to glow by someone and sold as a glow engine for models. I don't know by whom or when those were converted to glow and sold, but I know a few members on here with them.

I wonder if they modified the carb any, drilled out jets, etc. to make it work with glow fuel vs gasoline. Otherwise, it's a neat engine on its own.

Well that's interesting and I had to look around , check this out he tell about all i could find on the Kolbo Korp .>> https://www.flyinggiants.com/forums/showthread.php?t=101246 There are some sites for Technical Defense information center . that want load ?! 1980-88

Eric's link in his post mentions that the Kolbo Korp was a military contractor for drones. It could be possible that the Cox 140 Rhino engine was used in early military airplane drones of the day for target practice.

(Just think, being an "NCO technical sargeant", later designated Specialist 5, 6 or 7, whose specialty was to set up, fly and retrieve those drones, using say reed equipment of the day on military frequencies, what a way to earn a salary, almost as good as playing in the band.)

Back in the 1990's, I remember the large foam Carl Goldberg Mig-23's powered by a K&B .65 Sportster engine that the NM Army National Guard had, to be used with their air defense artillery simulators. The plane was 3 channel, motor, elevator, ailerons. Used military frequencies for operation. Came in a crate with about a half dozen aiplanes, almost RTF style. (One removed the engine, tank and radio gear, transferred them to the new plane, then good to go. Radio was organized in a tray with servos mounted. I think the aileron servos were separate in the foam wing.)

Later those drones sans the military radios (used standard sized servos) were selling as surplus on the various Internet auctions and a few other places back then into the early 2000's.
