I've done a search and found some information on this subject but I thought I would ask the question again to get some more input. My GP Skybolt kit arrived today. I've always liked the looks of this plane and I am eager to have one of my own. What engine have you found to be a good match for this kit? How does it perfrom with a .60 2-stroke? I'm leaning toward a .90 2-stroke, what experience have you had with one? What about 4-strokes? Which 4-stroke have you found is a good match? Thanks in advance for the help. Also, if anybody has any building tips or suggestions for this kit, I'd love to hear them.
