RV-8 Project
Below are links to my RV-8 project. I haven't progessed far. After completing the empennage I stopped to focus on my Pietenpol. I hope to get back to building the -8 soon.
From the Van's web page: In 1995, Van’s revisited the tandem concept and came up with the RV-8, a new design incorporating improvements learned from years of experience with the RV-4 and RV-6/6A. With a wider cockpit than the RV-4, two baggage compartments and increased instrument panel space, the RV-8 offers greater cross-country comfort without compromising the fighter-like sportiness of centerline seating. The RV-8 was designed to handle engines of 150-200 hp, and with the 200 hp IO-360 Lycoming, it sustains cruise speeds of 212 mph. Top speed is 222 mph.
