Purchased a 1/4 scale cub from an older gentleman at a swap meet today==still in the bones. I was wondering what size engine should I be looking at to put in this plane? The person I purchased the plane from had a stroke and he could not remember what kit it was. I need to get a window kit for it. Felt sorry for the older man, because I know that he liked to build and fly, you could tell that by the quality of the work that he had completed. Maybe I could take a picture of it and someone might know who the mfg. is.
