Location? Experience?
First off, welcome to the wonderful RV community, you made an excellent choice. VAF is the best tool there is, and the one you will likely use the most. Based on your "profile", the VAF community knows nothing about your location, or your capabilities or underlying RV knowledge..which is fine, however, many of the suggestions you get may be less helpful than with a slight amount of intel. Almost anywhere in the world there are RV builders and pilots within arms reach to help you dive in. If you live anywhere near central NC, I invite you to come spend a couple hours in a shop that has built an RV, and meet other RV builders including one that built a -7. I am quite certain wherever you are, there is a builder close by..and that's the best place to start. I ,and others on this site, have mentored many "newbies" from zero RV knowledge, to building their first airplane. The RV community is like no other on the planet. Just remember, patience is of utmost importance, but with VAF, answers come quick..back in the Jurasic pre-internet and VAF days it took us a minute to figure things out.
