Nacelles are rotating slowly

    The Nacelles rotate slower than what is viewed in tutorial videos. Even when rotating with the BFWS the Nacelles still rotate slowly. Any suggestions?

    1. Few things could affect nacelle rotation speed.

      1. FPS - All animations on MSFS are affected by the speed at which frames are rendered and calculated. Very low FPS would likely result in slow animations.
      2. Keypress intervals/refresh rate - the nacelles are designed to be operated with a constant keypress, as each press increases angle by roughly 0.1 Degrees. Press + Hold should move the nacelles at a rate of approx. 4 degrees/second. I guess different controller devices would have different refresh/sampling rates, resulting in slightly different speeds. A quick test would be to try keyboard keypresses vs joystick button presses and see if/how that affects the animation speed.
      3. Perhaps unlikely, but still possible, a faulty button. I've had this experience in the past with an old joystick, which for some reason it doesn't consistently pick up the button presses.

      The latter two wouldn't explain slow nacelle rotation on BFWS, though. If you share a video of the issue it would help us identify if we see anything odd and investigate further.

          There is another factor which can affect the "rotation speed", which I would consider a bug in the event handling.
          (I can send a video of that)

          Try this:

          • Press (and hold) the nacelle rotate button … in my case on the HOTAS throttle
          • now when watching the MFD inside the cockpit …
            • use the mouse … with right click … to adjust the camera view direction
            • this will stop the nacelle from rotating

          However … then I use the view joystick (2 way axis) on my stick to change the camera view direction … then the nacelle will continue to rotate perfectly.

          So it seems to me like the Ospreys code for the "nacelle command detection" could be enhanced to be more "robust". But then, I do not know how much of this command mapping is done by MSFS and how easy it is to customize on the aircraft side.

          I would hope that MSFS does preserve the origin of an event (e.g. a USB device ID) … because "modifier keys" (multi button mappings) can only be assigned within the same device. So two simultaneous events, which come from two different devices, can not be confused with "modifier" concepts.

          However, thinking about it a little further I would expect that the rotation is not only tied to key press counts … but in the case of a "press and hold" interaction … the time interval should also play some roll. Given that in the real world the hydraulic system does have some upper limitations too. I think that in one video the pilot said it is 15 seconds for a full 90 deg rotation? I might be wrong …

              I have seen the behavior you're describing in every aircraft in MSFS. A friend actually pointed it out to me a few weeks ago, because I had actually never really noticed, but using the Mouse Look features in the cockpit suspends all sorts of cockpit/flight control interactions. I think this is a general bug in MSFS.

              1. The issue described here is indeed a general MSFS bug.

                Thanks for the input gents, I have tested the switch I'm using on Thrustmaster Warthog Throttle, which I use as the Airbrake switch for all my fixed-wing aircraft on MSFS and DCS sims, and the speed to deploy works fine so it seems.
