    That button actually exists on the real thing but it's not used in the AJS. The other Viggen versions have the same stick and some of them use it.

    The button under the safety catch controlled sensitivity, or steering angle, of the nosewheel. However, the whole nosewheel steering system was redesigned after a prototype crash and the button lost its function, in the AJ(S). It got other functions on other versions.

    However, this button can be activated by pressing the safety catch down on it, in the real Viggen.

  2. The files have been released!

    19 years ago, today, the Viggen fighter flew it’s last operational sortie in the Swedish Airforce.

    We celebrate this by releasing our long awaited SUL37 Viggen stick project.

    Join the LAAT SUL37 Discord channel for a link to the files and get support or just discuss the project.

  3. Printing and testing different materials.

    The left half of the stick body is printed in PETG CF (Carbon Fiber reinforced) and the right half is PLA CF. The knurls, trim hat and SNURK button is printed in PETG.

    Here’s a video of the trim switch.

    Very nice! Depending on the outcome, are there any future plans for this project? Maybe crowdfunding and then sell DIY-kits (?) to all us Viggen freaks? 😀🤪

    Thanks!

    The current idea is to go the same route as authentikit. People will be able to print the parts themselves and source the switches and stuff, if they like. I’m also planning to put together hardware packs for those who prefer that. I doubt that I will be able print parts in any capacity so I will set up a shapeways account for that. In theory you could order aluminium prints, if you like.

    That’s the current plan anyway. I’ve never figured to make money from this and if people have suggestions and ideas, I’m all ears…

  5. Some of you people may remember my project with making a Viggen Stick Grip, from several years back.

    I started out making silicon moulds of a real stick, thinking I’d make a master plug and use that to cast wax copies and cast aluminium copies. Well, that turned out to be too time consuming and expensive. Then I figured I’d cast it in a two component alu-resin called TC-814 and that looked promising, until they stopped making the resin…

    In the meantime it turned out I suffer from a STD with a 100% mortality rate, called Life (this is a joke 😎). 
    So things have been slow…

    Then Authentikit emerged and sparked my interest. I made a functioning trigger and safety mechanism in CAD and I had the stick 3D scanned. But making printable copies from a scan, that would allow me to use the custom made trigger/safety mechanism turned out to be suboptimal. I tried to rebuild the stick in CAD, but the darned thing was probably hand crafted in the 60’s and has very few flat surfaces, straight lines or angles. It’s mostly 3 dimensional curves everywhere and it suffers from surface irregularities probably because it was sand casted and cleaned up manually.

    Then I got a tip about a relatively new 3D design software called Plasticity and OMG, this made a difference..! It’s perfect for these kind of designs.

    And If you have been brave enough to read all the way down here, I will treat you to a few pictures, showing you how far along the project is now…

    The stick with the holes in it is the 3D scan and the other one is my CAD copy.

    Here’s a video of how I did the knurling on the grip. A very tedious undertaking, I can assure you.

    And lastly a couple of pics of the foot.

    custom-made five-direction button rings (the directions enable left click/right click/scroll up/scroll down/disable).

    The rings are micro-USB rechargeable, and can handle six-eight hour sessions, with two weeks of standby time.

    @frenzon, thanks for making fingers! It works really great! 
    How can I get or make copies of your rings?

    Hi Goblin, not my design but I build one according to this thread and it works like a charm. The diagram is correct as is, green wires connected to green and grey to grey. Cant explain but it works. The magenta wires are connected, its a voltage divider. Two resitors between +5v and ground, and between the resistors you can grab 2.5v.

    Ok! Thanks for the input.
    What size adjustable resistors did you use?

    This looks like a cool project! I will try to copy your efforts, but I have some trouble understanding your wiring?

    I took the liberty of making a few notes on your diagram.
    Should green go to green, and grey to grey, like in your drawing? If so, how do you know which load cell that see the load? Or should the wires go crossed, like I have drawn? I mean, the loadcells should be able to differentiate between which one is being pressed? 
    Note that you may very well be correct here, but I just can’t get it to work in my head 🙂

    Also, what’s the deal with the 5V and GND? The magenta wires shouldn’t connect, am I right?

    I am most grateful for any help you can provide!

    Its "aircraft" ... lower case

    That didn’t matter, but well spotted.

    is there another SK60 mod folder or similar in there or do you get multiple folders and files?

    No, but it turned out I was being stupid.

    I was so sure I deleted the SK60 mod folder from the DCS/Mods/Aircraft folder…but it turns out I didn’t..! 😏

    Now it works with the SK60 mod folder in the saved games folder routing…

    Thanks for the help everybody!

  10. I can't install this mod... Granted, it's my first unofficial mod, so I'm probably doing something stupid..?

    First of all, I have no mods folder in my saved games folder.
    C:\Users\goblin\Saved Games\DCS.openbeta

    If I put the DCS-SK60-Mod folder here D:\DCS World OpenBeta\Mods\aircraft I get an error message when starting DCS about unauthorized mod and the folder got deleted.

    Is there something I need to do to get DCS to accept this mod?

    It goes like any aircraft mod into /saved games/dcs/mods/aircraft.

    I have never installed a mod before… Never felt like I needed one, until now 😉

    OvGME can install in DCS core or Saved Games

    I had mine set to the DCS root.

    So, move the entire SK60B folder into the …/saved games/…/aircraft/ folder, or?

    I tried looking at the readme file, but there was just a link under ”Installation”. Followed the link, but found no infor pertaining the installation there either…

  12. The SFI (pilots manual) for the AJS37 says that the airbrake can be opened partially by letting go of the airbrake switch, after it has been held backwards. 
    The DCS version seems to be opening fully and won’t stop when the button airbrake out is released.

    Furthermore, according to the SFI, the airbrake should retract automatically when landinggear is selected down. With gear down, the airbrakes only opens momentarily, as the switch is held backwards, and autoretracts when the switch is released. This doesn’t seem to be the case in the module…

    Am I doing something wrong or is this a known bug?
