John Stahr's Unique RV-8 at the AOPA Summit - AVweb One of the most aesthetically interesting aircraft in the AOPA Summit's Parade of Planes at Palm Springs this year was John Stahr's Vans RV-8. Stahr is a painter by trade and a pilot at heart. His ability to merge his passions has created an extraordinary artistic expression of his loves, in flight. And a paint job that's hard to forget.
