1. True - I initially hoped by keeping them small we'd cut raw material costs, but without low-weight materials we would be forced to go bigger. Probably the size of a Mr. Gutsy at least (they do manage to float off the ground with their extra limb weight, so I wouldn't expect it'd require more than their model, even if they could only be launched from a high location like Black Mountain).
2. I honestly figured the vertibird plans were
too advanced to be easily incorporated into what I initially imagined as, to Elijah at least, equivalent to paper airplanes. But good to know vertibird plans are relevant to this theoretical idea, so no real need not to pull the sword from the stone (if only we knew Pre-War Culture to make a King Arthur reference - fitting if we do so on the same turn as wiping out the final raiders, no?).
