I plan to buld the RV-10QB mostly by myself. Is this a mistake? When building the RV-10QB, how much of the riveting will require assistance from another person? Are two people required only occasionally for specific rivets where arms won't reach to both sides at once?... or are two people needed often during the build? I have built cars and boats, owned and worked on aircraft a bit, but I have never done this kind of riveting.
