Share this on: Van's Aircraft Original RV-1 - Youtube - AVweb Dick VanGrunsven is responsible for the most populous homebuilt airplane of all, the RV-3. Five years ago, Van's Aircraft enthusiast Paul Dye found the RV-3's forerunner — a heavily modified Stits Playboy that became VanGrunsven's prototype — and embarked on a restoration project. The rejuvenated "RV-1" is currently on tour with Dye and will find a permanent home at the EAA Museum in Oshkosh at this summer's AirVenture fly-in. We spoke with Dye and got a close look at RV-1 at Sun 'n Fun in Lakeland, Florida.
