  1. Hi, I also have Reverb G2 and I am using the stand-alone version. To run DCS standalone in VR I do the following:

    1. Plug in the headset/start Mixed Reality Portal.

    2. Start SteamVR. Normally it starts automatically when launching DCS, but I have on occasion had problems. When starting SteamVR manually everything works well.

    3. Run DCS in VR mode. I have set up a shortcut with the command line parameter --force_enable_VR, but this is not necessary.

  2. I would like to see a better "no mouse" option in VR.

     

    It is currently possible to put the mouse pointer at a specific place and then move it around by turning your head. In this way it is possible assign mouse keys to the HOTAS and click different buttons without using the mouse.

     

    However, since the mouse stays at a fixed position, it is hard to click buttons far down or to the side. For example, to enable the ejection seat in the F-14 you would to turn the head a full 180 degrees.

     

    A better option would be to be able to enable a "no mouse in VR" option in the settings. This would work by not have the mouse cursor in a fixed position. If you look up, the mouse cursor would also move up on the screen. If you look right, the mouse cursor moves towards the right side of the screen.

     

    In this way, it would not be necessary to completely center the button/switch in the field of view. For example, to enable the ejection seat in the F-14 it would only be necessary to turn your head to get the switch in the corner of the eye to be able to position the mouse pointer over it.

  3. If you are on Steam many modules are free to try at the moment, including the Persian Gulf map. See the newsletter a couple of weeks back for the free trial schedule. Note that there is one separate for Steam and one for the standalone version.

  4. I have noticed the same.

    Ex. in the F-14 if you approach the head to the mirror it's obvious that something is a bit wrong with the 3d projection. In some modules, ex. the Mig-21 there is no stereo vision at all, the mirror just looks like an LCD screen.

  5. I don’t think anyone mentioned that every time you release the trim button, you should quickly recenter the joystick.

    Unless you use a force feedback (FFB) joystick, or a stick without spring.

    This is not how it works in the real helicopter, but a workaround for spring centered joysticks that are most common.

  6. What's written is magnetic, what's said is true, regarding headings. That was my understanding.

     

    I think it's the opposite. Also magnetic changes slightly from year to year so it would make sense to have maps in true so they stay accurate longer.

  7. Did you select the bomb racks in the RIO seat, the same switches used for jettisoning?

     

    So I'm trying LANTIRN out and even though I think I have everything set up, the bombs won't drop.

     

     

     

    • My LANTIRN is on, warmed up, running, and I have an image on the TID and have designated a target.
    • I have set the attack mode to Manual, have set the fuses to instant electric and nose/tail for mechanical
    • I have selected a GBU-24 from the RIO weapon type drum
    • Laser is armed and set to 1688 which is the code on the kneeboard for that gbu-24
    • I've set to single delivery, qty 1
    • Master arm is on and mode set to A/G in both the front and rear seat.
    • I hit the release stores button when the counter reaches 0. When I do the TTG disappears and TIMP counts down to 0

    Nothing drops. I've tried doing it with holding down the pickle button and just hitting it but nothing. I've tried setting Jester to inactive as well. I also tried changing my keybind and just dropping a GBU without a target to see if it will just plain drop but again nothing drops.

     

     

     

    What am I missing? Thanks.

  8. CTD in F-14, last time just after releasing some snake-eyes. Nothing in the DCS logs. This error in the event log:

  9. I think we are talking past each other. In your Wikipedia quote even you say that a helicopter is statically stable (it will roll back level) but dynamically unstable (increasing oscillations around the statically stable point). I’m not an expert but in a turn you of course have other forces acting such as centripetal force (changing what the helicopter perceives as being the down direction) and maybe gyroscopic precession because of the turn rate that might counteract this statical stability.

  10. Nope. Not a chance. I hope we dont need to go there again, I think msalama with me on this.

     

    You should read this thread. At least the first post and #64, #68, #69

    Its already sorted out. We might wanna leave it out of this thread ?

    Then the Gazelle is also wrong since it seems to have a preference to hover with the skids towards the ground when keeping the cyclic centered (stabilization deactivated). It might drift around a bit, but not start rolling over.

  11. If while banked you were to then put the stick back to centre, blade angles become symmetrical(ish), the torque that caused the roll would disappear and then the weight of the body of the aircraft displaced from its natural position hanging under the rotor, would provide a torque that rolled the aircraft back to level with the COG under the point of suspension.

     

    This completely makes sense to me. A heavy helicopter hanging under a rotor with symmetrically angled blades should roll back more or less level.

     

    Yes, thought along similar lines too, but someone supposedly in the know disagrees.

     

    Wish I could up-rep you for your patience.

  12. Here's a video I made comparing the Gazelle cyclic behavior to the Hip (I know, vastly different helos), even without the Hip to compare to, looking at the control indicator, you can see it's just weird. You can see an obvious deadzone, and once you pass it, any input you give will continue to roll or pitch the helo in that direction until the cyclic is centered again.

     

     

     

    Good video, was thinking about doing one myself, but am up in the alps away from my computer for some time. When banking in the gazelle if you engage the magnetic brake (trim), keeping the cyclic left, but centering your joystick you get a similar result as keeping the cyclic left in the mi-8. No rolling over.

  13. I havent bought the DCS Gazelle(yet), but are looking into this meanwhile I wait for the Bo105 module, thats why Im following the threads.

     

    Did you try the module at least? I have no problem with the Gazelle being sensitive on the controls, twitchy, etc. with minimum cyclic input. What I am talking about is that any input from the joystick (your computer joystick, no matter the position of the cyclic) causes an accelerating rolling behaviour.

     

    A small experiment to show the problem: while hovering, use either magnetic brake or trim hat to trim the position of the cyclic forward. The helicopter will start to accelerate forward as expected. The helicopter will not keep rolling forward, no corrections are necessary with the joystick.

     

    Instead of allowing the helicopter to accelerate, recenter the cyclic to the starting center position through joystick deflection. You will then get the accelerating rolling backwards as long as you apply a joystick deflection. The behaviour is the same wether SAS is enabled or not.

     

    That being said, this is nitpicking and I still think the Gazelle is a blast to fly. And as some people say it seems that Polychop are working on improvements so hopefully this will be resolved at some point.

  14. The Gazelle is a french helo, main totor is rotating clockwise.

    This means the stick will be needed to displace a bit to the right during forward flight to keep it from rolling left( different displacement in different speeds).

     

    This flight test report show this clearly on page 47 ( Lateral control position):

    https://apps.dtic.mil/dtic/tr/fulltext/u2/a016921.pdf

    There’s a lot of info about how the sa342 handle, and good data for making a fine flight model or checking the validity of the actual one in this report.

     

     

    Here is a good video of a SA341C. The camera is static so you an stick a post-it on the screen to see how the position of the cyclic varies slightly during different parts of the flight.

  15. I've tried with and without the AP but it seems impossible to hold your attitude in the Gazelle.

     

    For example, if you bank, even slightly, then it just keeps rolling until you recenter the cyclic. It feels like flying with an ancient digital joystick. Is this correct behaviour?

     

    I would think it's not normal, and it's only the Gazelle that behaves like this in DCS. Also see the following comment by Damcopter, which has IRL experience of the Gazelle.

    Also setting the position of the cyclic with the trim vs positioning it using joystick deflection behaves totally different. If you trim the cyclic to a certain position and do not apply any joystick deflection you do not get the rolling behaviour.
