RE: GHQ engines
Back in the early forties when the GHQ hit the market, I was very active in free flight. We ran Bantams, Ohlssons, Tiger Bunches, Dennymites, and Brown Jr's. These engines powered Zippers, Sailplanes, Buzzard Bombshells, Clippers, Buccaneeers, Interceptors, and many others. It was always nice to see someone show up at a free flight contest with a GHQ powered model, because we knew that he would spend the entire day trying to get it started. I saw a lot of GHQ's, but never did see one run. The GHQ you talk about that runs is a "first". Put it on E-bay - you might make a fortune - after all - you can say that out of 100,000 engines produced, this one runs!
