The First "RV-8"
...was two RV-4 fuselages joined together in this configuration. The concept was that you could buy a Piper Apache junker, use the engines, feathering props, and retractable gear. Supposedly it generated interest among those who didn't realize that the issue of the RVator announcing this plane was the April issue. And Van's supposedly spent a lot of time explaining to folks that it wasn't a real plane...
Still, the RV-66, tailwheel/nose, un/primed, all that, makes for some good stories.
