So is it just me that have these issues? Would a reinstall fix it if so? Regards F

You mean -3 degrees, right?

I was looking at this chart: The green line is MS The yellow line is for Stage2 The red one is for Stage 3 My weight in the videos is around 13000kg but even at 19kkg the rotation speed is below 250 with stage 3. But it’s not possible to get any response before 250 in dcs.

I’ve had problems taking off without over rotating, so I finally tried to find what I was doing wrong. I’ve made 3 videos when I take off, one with full military (MS), one with AB stage 2 & one with AB stage 3. Clean AC, 60% fuel, trim 0, weather 15C. MS: http:// https://youtu.be/w5CYmls1W8U Work like I thought it would, rotation at 280 to 10degrees, only thing is that it’s very sensitive on the stick. AB stage 2: http:// https://youtu.be/uQzZj-tP1q0 Also work as I thought, rotation at 250 to 13 degrees. AB stage 3: http:// https://youtu.be/gel28B6s0gY Does not work, it’s not possible to rotate before 250 and because I pull too hard to try to rotate I over rotate when I hit 250. With my load out and temperature I should be able to start rotation at 150 with AB3. For AB2 I should be able to rotate at 220. But I can’t start rotation after 250. The G’s: In subsonic speed: http:// https://youtu.be/mOL24Ok8Wnw Normal I’d say, the possible G to pull seems to correspond to the charts. Supersonic: http:// https://youtu.be/kK83ZsMcQN8 Not normal, it should not be possible to pull this many G with such small stick movement. I’m maxing the G gauge with a 1/4 of stick movement.

AJS-37 overall behavior changed with the latest patch? It’s from a aerodynamic compendium, here is a screenshot: (in Swedish though) I think there is something off with the added lift when the “canard flaps” is down, and that’s why it feels like there is a sink down even with afterburner, and a high alpha.

Actually you shouldn’t take off without afterburner even at lower weight, the drag risk to get too high. You need to get to 300km/h to have enough speed to continue accelerating without afterburner, the alpha at lift is 11 and it’s easy to over rotate and stall. With a 60% fueled ac it takes 8 second from start to lift off and then another 18 seconds to reach 600km/h. That’s why it’s important to raise the gears short after take off. Take off with afterburner should be done with minimum 50% of stage 2 due to risk of AB flame out with lower AB. On take off the max speed due to the rotation of the gears is 320km/h and the risk of hitting that speed is said to be low. The problem is that it’s impossible to rotate before 250-260km/h, at least for me :)

How many g were you pulling when it brake? The viggen has some limitations to how many g it’s possible to pull att different altitudes and speeds, but at mach0.8 at low level it’s possible to pull 12g and that is above what the airframe can take. But I don’t know what it would take to get there, I guess a fast, full aft pull could do it?

It doesn’t sound too far off actually, with that load and stage 2 your speed of rotation would be above 260km/h at +30C But I’m not sure about the high AoA. What if you use a clean AC ? A clean AC with 100% fuel weighs about 15000kg. At +30C your speed for rotation is 195km/h with max AB stage3. 180km/h at +15C. A really cold day -15C the chart show 165km/h but the minimum allowed speed for rotation is 180km/h. But I can’t rotate with an AC with 70% fuel below 250, it’s just not possible for me. If we look at max AB stage 2 the speed of rotation for clean AC 100% fuel is 240km/h at +30C and about 225km/h at +15C.

Awesome, thank you!!

Hmm, I’ve seen a sort of hud that show your stick inputs, how do I activate that?

I can’t take off without getting a high alpha warning. Even with a clean ac @70%fuel I will trigger the warning. The ac won’t react to stick input below 280-ish kmph and even if I have a very small stick input when I hit this speed I will get a warning as soon as I get close to airborne. So my questions are: -How do I take off without triggering a high alpha warning? -Why doesn’t the aircraft react to stick input before 280-ish kmph? When I read the take off diagrams I see no reason for this. Regards F

When I had a rolling issue it was my rudders (foot pedals) that needed a bigger dead zone.

Sure they will, let say that you think that the AC is too sensitive in the center region of your joystick, you then adjust your curve so it’s less sensitive in the center region. The drawback is that you will have a higher sensitivity somewhere else along your stick throw. But who can say if it’s more training needed to learn to handle that sensitivity or if it’s the FM that is wrong? I will always blame the FM, I have flown the F/A-18 Interceptor on the Amiga 500 ;)

Any FM that you can learn to fly without adjusting any curves on the joystick is a good FM. If you can’t fly it without adjusting curves it’s either a bad FM or you need more training.

I was wrong, the first seed planted for the AJS37 happened in this thread: Får vi höra lite glädjerop? https://r.tapatalk.com/shareLink?share_fid=57647&share_tid=661&url=http%3A%2F%2Fwww%2Emasterarms%2Ese%2Fforum%2Fviewtopic%2Ephp%3Ft%3D661&share_type=t

I'm not sure, but in theory it should, there was a Viggen thread before the AJS was released but I can't find that one now.

Terrible life-decisions: How a DCS-module is made Haha, ok, no snail had nothing to do with the AJS37, it was a forum members effort at first. 4 of those listed above were the guys who took the idea of a AJS37 into action. This was back in 2012 something I think.

Terrible life-decisions: How a DCS-module is made I remembered wrong, this is how it started:Får vi höra lite glädjerop? https://r.tapatalk.com/shareLink?share_fid=57647&share_tid=661&url=http%3A%2F%2Fwww%2Emasterarms%2Ese%2Fforum%2Fviewtopic%2Ephp%3Ft%3D661&share_type=t

Maybe I'm reading it wrong, but if we are going Mach 1+ , why doesn't it work above 14k?

I think it would depend on the airspeed and alpha you had when you engaged the alt hold.

TIPPVÄXEL problem Yes, there are specific numbers in the SFI, can't remember them now.

I set the bottom saturation to 65 with 0 curvature, it's less erratic and with full stick it corresponds close to the SFI figures in G. Without the saturation I got max G at about 60% stick movement the last 40% just acted like a air brake.

Doesn't the canard flaps create a nose up and that's why the elevons are dropped to counteract this? If so, when you give stick aft the canard flaps should make the nose go up? Either way, with zone 3 you should according to the SFI be able to rotate at 190kmph, if you are low weight it is even less but the restriction is 190.

Nose heavy on rotation? You can always try to do a aerodynamic brake when landing: -Softly raise nose to max alpha 16 -put nose wheel on ground at about 160kmph - steer and wheel brake - reverse if needed Do it with a clean ac with less than 80% fuel.

I can't see them move, but when in external view and looking at the bottom info bar, the FLP goes rapidly between 99-100 when in air with gear down.
