RE: what is a "glow" plane? Does it use fuel? How does the engine work?
Glow planes are what the average person would call a "Gas Engine Plane". The fuel they burn is a mixture of Alcohol, Oil, and Nitromethane
We use the term "Glow Plane" (Because of their Glow Plug) to distinguish them from the really BIG planes whose engines actually burn gasoline (and use a conventional Spark Plug)
