"early" gyros...how far back are you going?
Fair point well made...
A better example may be is the design concept pre or post the CAA Glasgow report and the evolution of Section T. Obviously there are crossovers and types originally designed "pre" that had been modded to improve stability and so on and make them more like "post."
PS see that little-wing does look very cool, in the opposite way from how the MTO Sport manages to also look cool.
