Not for me, I much prefer the looks of older style tractors like the Detroit News and Beechnut examples to the modern pushers. But then I'm an artist who has ignored art theorists for quite some time. If you really want to learn about what's up with electric propulsion re. modern light autogyro design, a great place for info on innovative experiential information is in the modeling community, especially here: https://www.rcgroups.com/auto-gyros-224 Twin rotors are considered easier to work with in models than the more complex single rotor. I'm not sure gyro models show the same ground looping tendencies that conventional gear fixed wing models do. But a lot of interesting questions can be answered there, and many other interesting things learned. There's a lot more open development and innovation at small scale than large. Yes, yes, I know, models aren't real airplanes, effects don't necessarily scale, Reynold's numbers are different, etc, etc, etc. nevertheless..... Reminds me of a theater acting crowd story passed around -- Maria Callas I believe, performing at the London Palladium, the announcer introducing the great opera singer was interrupted by a drunken heckler in the audience, who shouted out, "Maria Callas is a @#&%!" The annnouncer, unflapped continued, "Nevertheless........Maria Callas, ladies and gentlemen!".
