  1. Indeed, the first video appears to be exactly like what I'm seeing in the DCS Viper. I fly planes for a living IRL, even big jets, but nothing like the Viper, and we certainly do not maneuver like this jet is capable of. Based on watching these vids, it appears that I'm incorrect in my analysis. Thanks for that. Cobb
  2. Ok. Just track files or videos? Let me see what I can work up...
  3. I was playing around with the flight model while trying to set up my pressure sensing stick, and I realized that the flight model, in particular the roll axis, seems to be incorrect. The DCS Viper had always seemed to fly a bit odd, not intuitive like a real airplane, but I could never figure out why. Something is off about it. I read numerous comments on the forums, and watched several videos, that have this odd pitch-up moment when rolling out of a turn to straight and level. It's done it to me, and real aircraft (even other DCS aircraft) don't do this. Why the DCS Viper? I've trained my muscle memory to pitch down when rolling out to hold an altitude, but this is not a trait with real airplanes. I think I've found out why it acts this way. I was doing some high AOA flight to sort out stick forces to hold different steady nose-high attitudes, and discovered that ED has programmed the rolling axis of the Viper to be on the Flight Path Marker, not the gun cross in the HUD. In any airplane, there are three axes of rotation (pitch, roll, yaw) that all intersect at the Center of Gravity. Every airplane, no matter the pitch condition, the ailerons (and stabilators) will only roll the aircraft about this lateral axis, which runs down the center of the fuselage from front to back, parallel to the long axis of the fuselage and does not move or change with AoA. This axis is depicted by the gun cross on the HUD. If I pitch up to 30 degrees AoA and then roll the airplane, the roll should always center on this axis (the gun cross), not the FPM which in this case will be well below. In this case, I would end up in a nose high turn and the nose would not roll through the horizon like it does now. But the DCS Viper rolls around the FPM with high AoA. You can see this by setting up a high AoA flight and inducing a roll. The gun cross will move laterally around the FPM, when it should roll around the gun cross and the FPM will then adjust to the direction of flight. There is one other thing that can contribute to this behavior. In the flight control software, rudder is added to the roll input to assist in maintaining coordinated flight. This is designed to counteract the situation of adverse yaw (where the nose points opposite of the direction of turn due to drag increase on the outside wing). Most airplanes compensate for this in various ways, and the Viper is no different. Rudder is added to the roll input by the flight computers. Again, in a real airplane I can manually duplicate this odd behavior by inputting positive rudder with aileron. But this would technically be a poor technique, as adding that much rudder would induce a skid, which is too much rudder input for good, coordinated flight. I'd like ED to have a look at this and see if I'm correct. It may be simply adjusting (reducing) the rudder input in the FM. The biggest issue I've seen is the weird pitch up when rolling back to wings level and having to add significant down stick to maintain an altitude. Cobb
  4. How do we set up the CTRL + SHIFT + (key)? I can get the CTRL or SHIFT to show in the Keybindings setup, but not both.
  5. Why do we still not have the ability to copy F10 map coords via a key combo to the clipboard, for importing into our kneeboards, text files, etc? This is a request over a year old, and with VR getting ever more popular it seems a quick, easy, and critical feature to have. Cobb

  6. Using the A-`10C II and both SSA Beta 2.1.2.0 and Stable 2.1.0.0, neither has any gun vibe. Going from 0-100, checking and unchecking the box gives no effect. Seems as though everything else is working, just not the gun. It used to work, now doesn't in the last couple days. BTW, the drop down only shows the A-10C, not sure if it should show the A-10C II as well. IRL, that GAU-8 will shake your fillings loose. Cobb
  7. The only way to manage it would be to set up a private JDF arena that's password accessible. It'd be the only way to screen out the riff-raff. Any time you allow public access to anything, the losers will show up at some point.
  8. Is this still a thing? It’s an old thread, I know. I retired out of JSTARs, would love to see what this is.. Cobb
  9. As a retired JSTARs ABM, I’d love to get that. I’d be very willing to help someone develop it too. Cobb

    Easy refueling

    +1 This! Also, a Disconnect call, and the PDI lights need to be a bit brighter. BTW, the PDI's are part of the boom, not some magical Fresnel lens that always works with every airplane. Cobb
