Wow this pic post thing worked!? Now to figure how to make it bigger? 
THe top photo has the original rotory engine which is what makes the plane. Many copies exist using a radial contential engine note also the tail wheel instead of skid. Also the Radial engine retro fits often moves the engine cowling/fire wall back extending the nose. Nice. But kind of like taking the self-winding swiss movement of a Rolex and replacing it with a batt operated quartz movement?
