One of the first 4 Strokes to hit the market in the early '80s was this Kalt .45. It was manufactured by Kalt Sangyo of Tokyo, Japan and was one of my most reliable and greatest flying engines for my planes. It needed no muffler and used no or low nitro content fuel to run.
I decided to run it for all of you to see and here.
Thanks for watching.
