I am considering ordering a Rans S21 kit. Although I've researched the topic on Experimental aircraft, I'm still somewhat confused on the 51% rule. I'm a Canadian and may not have the time to complete 51% of the project myself, so it might require hiring someone else to help me build it. The question is, if I don't build 51% of it, what issues do I run into it if I want to sell into the American market?
