...still wish there was a V8 PSRU kit for a V tail.
A V8 V tail.

Fond memories. I once flew a Porschooney in Germany and had the opportunity to talk to some of the engineers. It was a nice flying machine, but they surrendered to the high continous power output environment of an aircraft. They never figured out how to really deal with the materials stress and simply gave up. Sad, but I would say the todays value of such unicorn is just history.
