One of the main problems with current helicopters is the overwhelming complexity. paul314 October 20, 2020 11:11 AM It would be nice to see something that isn't a render. Perhaps even something actually flying. All the cyclogyros that have made recorded flights seem to have rather larger wongs/rotors in comparison to body size and weight. Tad October 20, 2020 06:44 PM Look up "Tom Swift Jr. And His Ultrasonic Cycloplane." Not really the same thing, but much of the description is familiar. Catweazle October 21, 2020 08:51 AM guzmanchinky says "One of the main problems with current helicopters is the overwhelming complexity."Have you seen the Kaman K-MAX rotor design which entirely dispenses with the expensive, complex rotorhead?I cannot understand why use of this proven design is not much more widespread. Nelson Hyde Chick October 21, 2020 11:35 AM This design seems like it would be burdened with more drag than a conventional helicopter. Bruce H. Anderson October 21, 2020 11:53 AM I wonder if it could be combined with a wing (like the FanWing? https://newatlas.com/piloted-fanwing-aircraft-debut/23398/) to allow VTOL and also take advantage of aerodynamic lift for longer flights. Signguy October 21, 2020 11:57 AM Catweazle: good question; why AREN’T they used more? Nobody October 21, 2020 03:04 PM Need more data but the rotors look too small to be efficient. Towerman October 22, 2020 12:53 AM @Catweazle too cluttered and double the components needed for 2 rotors and old design. Simply go direct drive on the mainrotor and direct drive on the tailrotor, problem solved: https://ae01.alicdn.com/kf/Hdae50cbd4f5c44688269a6202cfd3ffen/OMPHOBBY-M2-6CH-3D-Flybarless-Dual-Brushless-Motor-Direct-Drive-RC-Helicopter-BNF-With-4-IN.jpg_q50.jpghttps://rcmarketpuss-rcmarket.netdna-ssl.com/images/D/OMPHOBBY_M2_6CH_3D_Fl2.jpg BruceNAnnWilliams October 22, 2020 07:22 AM Two words:Moving Parts Anyone familiar with rotary wing aircraft would be just a bit skeptical of this design.
