I have included a picture below of a complete airframe standard kit (slow-build) for the RV-7. Essentially, the RV-7 and RV-8 are the same except for the cockpit configuration. The RV-8 is the centerline tandem config while the RV-7 is side-by-side. Specifications and performance are very similar. I was unable to locate a similar picture showing the RV-8.
