This is a Class C .35 size engine ( Buzz). I was given this engine many years ago. For something to do I though I'd like to run it. The plug you see is an old glow plug. I remember seeing these engines advertised in model mag's years ago. Price was cheap so engines were probably not the best quality. As I remember they ran from 19 all the way up to 60 size. My engine is missing the drive washer. Picture shows a slot in the crank shaft to secure the drive washer from spinning on shaft. Whoever had the engine before me added three brass washers in place of original drive washer. It feels like it has fair compression. It has a couple broken pc's on top of cyl. Anyone ever run one?

I think that's one of the slag engines. If it is, it has a steel piston running in the aluminum crank case, and it won't last long once you get it running.

Indeed, a slag engine.
Rumor was, you could break them in and wear them out in the same flight. LL~ LL~
As I recall, there were other slags: Rogers, Genie, Thor, RAM, maybe more.
Want to see some more pictures of them?

GHQ was not a slag engine.
Cast iron cylinder, steel piston.

No, but it was a POS! FWIW, I was at the Sierra Eagles field sometime in the 1980's for a "Sierra Cup". Downwind, some local guy was flying an R/C Taibi "Powerhouse". It went straight up in an obscene display of horsepower. I asked one of the local guys about it. He said it was powered by a GHQ...one that had spent months, with mega-bucks spent, on Bill Wisnewski's best efforts. That guy was a genius. y1 Steve

The story that I heard was that the original design was good, but the designer sold it to American Hobby Center, who built it cheaply. So after it's blueprinted, it's a fairly good engine.

Tim, did you ever run that antique from Ebay?
-
Yep slag engine but maybe one of the better ones because they "give a guarantee of at least 5 years."

I forgot that I had posted the Buzz 35 on RCU back in 2009. Briggs/ Stratten made cheap lawnmower type engines with the aluminum cyl. Would start to smoke after a few hrs running. They later used a steel liner, a big improvement.Richard

The GHQ is a poorly-built copy of the earlier Loutrel engine. Some of the GHQ engines actually ran! I had one which would run. It turned a 12-6 wood prop at about 5K RPM. Heavy as they could make it!
People have rebuilt these engines with a custom piston and a con rod which would last.
