F4 / RV4 PROJECT FOR SALE • $110,000 • ONE-OF-A-KIND • Design: It starts as an F4 Raider with Sport wings (Phlogiston spars), then adds cheeks of the RV-4. This was necessary to accommodate the IO-360 Angle Valve engine. That is why I named it a PHAT-4. There is no other airplane like it. Please look at Vans Aircraft RV4 page. You will see a red and polished RV4 posted as an example of the finished product. It was my starting point for this PHAT-4 idea. • MORE INFORMATION • Contact Ron Patterson , Owner - located Queen Creek, AZ 85142 United States • Telephone: 510-421-2316 • Posted March 21, 2023 • Display Specs Page • Show all Ads posted by this Advertiser • Recommend This Ad to a Friend • Email Advertiser • Save to Watchlist • Report This Ad • View Larger Images
