For you guys who aren't Old Timers, gas/ignition engines in the small model airplane size aren't at all a new thing. Sitting in my workshop, for nostalgia and memories of days long gone by, is an engine display with a GHQ .56 gas/ignition engine and the ignition components necessary for it to run. I enjoy having shop visitors put their fingers on the spark plug while I flip the prop, for a "shocking" experience. Everything on the display, the two flashlight batteries, the condenser, the switch, and the ignition coil, all had to be carried in the model airplane so the engine could run, and the plane could fly. The ignition points on the GHQ happen to be from a Ford flathead V-8 car engine. The GHQ ran on a mixture of gasoline and heavy oil.
