-Nimrod- Posted March 3, 2022 Share Posted March 3, 2022 I am experiencing the same sensitivity issue. I also paused flying the Viggen a bit and just recently came back to it. Not 100% sure if it was always like this but I would also say that this is something that came up in the last patch. I can rule out that it is something related to the input signal of my rudder pedals. I checked in the axis config and everything looks normal (no hard-overs at small pedal deflections or something like this). I made a short Video which demonstrated the issue in flight (see attached). At the beginning of the video I am just giving a very small ruder input and the nose is already all over the place. At the end I briefly apply full rudder. Watch the rudder pedals in the cockpit to get a feel for how much rudder I applied initially vs. what a full rudder deflection looks like. Since the pedals in the cockpit reflect "what DCS sees" I again, can rule out an issue with my rudder pedals. It seems to be related to the flight model. I have no issues like this with other modules. I tried with and without SPAK, different loadouts, fuel states and airspeeds. All lead to a similar result. Off course I can work around the issue by applying a ton of curvature but I don't really think this is the way this should be modelled. Unless the Viggen had a REALLY sensitive rudder. The video was recorded with 0 curvature by the way. Rudder test.mp4 Link to comment Share on other sites More sharing options...
Lagnad Posted August 4, 2022 Share Posted August 4, 2022 I also have this. And I also have the MFG crosswinds. Maybe a connection? Link to comment Share on other sites More sharing options...

If you turn on SPAK, the SAS applies a strong, momentary opposite rudder to damp the yaw rate (maybe also the sideslip) but that introduces a pretty strong opposing roll moment. By the time the roll rate damps (unsure if natural or SAS) it has rolled between 60-90 degrees. I don't know if this is true to the real design or intended behavior.

Machalot Posted August 8, 2022 Share Posted August 8, 2022 I asked the HB team to take a look at this and submitted it to the bug tracker. 1 "Subsonic is below Mach 1, supersonic is up to Mach 5.
