John Stahr's Unique RV-8 at the AOPA Summit - AVweb Watch in HD on YouTube! Share on Facebook! 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.
