RV10 Build Section 29 Fuselage Sides- Part 2 Drilling - Video 39 - Pilot Rhino Watch in HD on YouTube! Share on Facebook! Section 29 for the Vans RV10 is the section that most builders say is the hardest. I have been planning this section for six months, talking to builders, asking questions, gathering notes from previous build blogs, online forums and the RV10 Wiki.
