  1. TIPPVÄXEL problem Yes, there are specific numbers in the SFI, can't remember them now.
  2. 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.
  3. 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.
  4. 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.
  5. 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.
  6. I'm not sure that it's the TIPPV. that's the problem here. I flipped the TIPP VÄXEL to Till and this should give a pitch input gearing that correspond to landing speeds. And I see a difference with in on. The question is if the outer elevons have a exaggerated movement? The outer elevons should give you fast and precise corrections but instead it gives fast and exaggerated corrections. It's even possible do 25G pulls. Are we perhaps missing some dampening effect ?
  7. No, I don't think it should do much difference but I just noticed it's there and it shouldn't be afaik :)
  8. I forgot to mention that it's with gear down, untouched from take off.
  9. If I fly at low alt and M1.1+ and move my stick fast about 10% I get about 7G readout on the G-meter. Why is that ? Shouldn't I get a smaller output from that?
  10. It does work but it doesn't illuminate the tail. Cobra said it will be fixed in the next update.
  11. No, I feel this too, it's impossible to start rotating before a certain speed, it's like elevons doesn't have authority before that speed. If you pull the stick full aft as soon as you start, nothing will happen until you suddenly have your nose looking at the sun :) So to take off smoothly I need to apply pitch up after this speed. If I start pulling before I tend to pull too much.
  12. Noticed when I did a take off from external view that when I got airborne the flaps start to rapidly change between 99 to 100%. On the ground it show 100% steady.
  13. I've checked that, and I checked with ctrl+enter to see if the brakes move if I move anything else. So your nose wheel does not compress if the aircraft roll to a halt without break input ? It's visible to me from external view .
  14. I have the opposite feeling, it's like it's always on. If I start rolling and pull back to ground idle, the aircraft will stop like if there is brakes applied. The nose wheel compress just before the stop. I could be wrong of course but why would it compress if it just rolled to a stop?
  15. I'm almost sure that I've read that they couldn't be fired from the center, it was just for transport.
  16. Is there a different flight model when you are on ground vs in air?
  17. Speed at rotation Well, to be honest, I don't know what the manual says. I'm looking at the charts in SFI AJS37 part 2 chapt IV page 11. And I see I misread the recommended airspeed, it says that the SI show the recommended airspeed as 250kmph. And it also say that the minimum allowed speed of rotation is 190 kmph. But the chart show that it can be done at lower speeds.
  18. Speed at rotation The thing is that I can't even lift the nose until 230 something. So it's not possible to rotate too early for me. And if I force lift it at that speed with full aft stick, I'm at alpha 20 as soon as there is some lift(because I'm full stick aft and over rotating) If should be able to rotate or at least start to rotate at 165 kmph given my weight according to the charts. I'm at 50% fuel =2000kg of fuel Ac + driver is 10749kg So my TO weight is 12749kg
  19. I'm reading the SFI part 2 and with a weight of 19 tons and +30C the minimum recommended rotation speed in the SI is about 235 kmph. My problem is that you can't rotate the aircraft at that speed even if you weigh 13 tons. This is with zone 3. The chart say that with MS and a weight of 17 tons and +30 the SI rotation speed is about 305 kmph. The chart don't even show higher than 17 tons for MS so perhaps there is a restriction there?
  20. But can you do it before that speed?
  21. I've tried to do some short take offs but there are some things that I can't get my head around. No matter what the aircraft weight, I can't start rotate before 250kmph. According to the charts the minimum recommended speed of rotation is between about 150-220 kmph depending on weight. The recommended would imply that it could be done earlier but it's not recommended, right? But I can't do it on a clean aircraft at 50% fuel, not even at 20% fuel. The nose will not raise until the speed reach about 250 kmph. Am I doing this wrong?
  22. I've just read a book about the viggen and how they overcame the problems with the aerodynamics. There are pictures that show the pitch moment for the viggen changing with Mach. These pictures show a positive pitch moment until the transonic region where there is a pitch down followed by a pitch up and the a decreasing pitch moment as the speed increases. But in the sim it feels like there is a negative pitch moment even in the subsonic region, I have to trim pitch up a lot to make it fly straight. Wouldn't a positive pitch moment mean that there should be a "nose up" instead of a "nose down"?
  23. I had some trouble with them yesterday, I used the scroll wheel on my mouse and could turn on the side panels and front panel (the light came on if I rotated the anti clock wise) but I couldn't get the flood light to turn on. I got the tip to use "click and drag" instead. And then the knobs turned on the light if rotated clock wise and the flood light worked too.
  24. The light that was pointed at the number of the stabilizer is now pointed at the body of the aircraft. The rotating anti collision lights can barely be seen at night ( this could be a graphic setting perhaps) but it's like the light is too small and is inside a black painted glass.
