Its 51% of the aircraft that must be fabricated and assembled. There are no limits on the number of builders who participate or how many manhours are spent on the build as shown in the links above. But at the end of each build, there will be a regulatory review to ensure the aircraft meets the 51% rule.
While I wouldn't consider a Rotorway to be a good example of the current slew of E/AB helicopters, it probably would be the one that would fall through your roof. Better examples would be the turbine Helicycle, Mosquito, Safari, or especially the Hummingbird given its design history, which have a much better combined record than the Rotorway.
