70" Revolver Engine Question
I recently purchased a GP 70" Revolver. I was a little surprised at the recommended engine sizes. Up to a 75 Two Stroke and 91 Four Stroke. These sizes seem very conservative based on the size of the plane (70" SPORT Plane). I am planning to use a four stroke engine and I was curious to see how many have actually built the plane with a glow engine and what size engines were used?
