From 2024 (YouTube Edition): Developing STC For Fly-By-Wire In R-66 Rex Alexander spoke with Warren Curry of Skyryse about the Supplemental Type Certificate (STC) SkyRyse is developing that it anticipates will be certified in 2025. The STC is for a fly-by-wire system named SkyOS, in this instance for the Robinson R-66 helicopter. SkyOS is very different from what helicopter pilots are used to. Instead of using a collective, cyclic, and pedals to control the aircraft, SkyOS combines all of those parameters into one side-mounted stick that the pilot uses to control all the same flight parameters. In fact, the Skyryse One helicopter is an adaptation of the R-66 with all the modifications done to the interior and control systems: sidestick for control but no collective, no cyclic, and no pedals.
