Happy to say that I have finally joined the family. The seller and me were able to get our schedules aligned and my "new to me" RV4 has arrived. It does need some love and upgrades that I want to do so will be a project over the winter. I, unfortunately, will not be flying it this year. It is just not worth it to insure it for a few weeks before our field gets snowed in, so I have decided to do the upgrades that I have asked about in this and other threads. Panel, lighting, rear rudder pedals (maybe for insurance), and just general making it into my aircraft.
Thanks to those that have given me input on my questions. Many more questions to come now that I have some physical to relate to.
