  1. I said that the difference between inner & outer wing rudder disappeared soon after take off. I did a flight today and the outer rudders move up during deceleration and down when accelerating. -Is there some kind of auto trim logic in SPAK when in landing config? -When I pull full stick aft, in landing config, the inner rudders only go about 5deg over the horizontal plane, I thought that max was 22 degrees for the elevator. In SFI part2 page 34 it says that up to Mach 0.85 the stability is positive so that during deceleration you have the use aft force on the stick. - I don’t know any aerodynamics but wouldn’t that mean that during acceleration you would need to push the stick forward? In DCS I need to pull aft during acceleration. On page 37 it says that at M0.95 there is a small nose down change in trim that at M1.03 get negligible when SPAK is active. -In DCS I get a nose down and a nose up trim interference. Is SPAK working as it should?
  2. Yes this is better with your mod. I thought it was good a few updates ago too but something happened on some update.
  3. I think this video shows better what I mean: http:// Trim is set to zero here. First I move stick forward and back to center, the aft and back to center. The outer wing rudder is not drooped as the inner, they both should be, but the outer returns to level when the stick is centered. It behaves like this some time after take off too and then they both droop and behave as expected. The outer wing rudders should follow the inner wing rudders movement, but they don’t on ground and some time after take off. The autopilot can steer the outer rudder up to 10.4 degrees from the inner rudders but that it does this on ground doesn’t seem right. Never seen this on a live video. If you look at a live video of the Viggen take off you see that the outer and inner rudders are drooped and “connected” until the stick is pulled aft.
  4. When I’m on ground the rudders doesn’t move as I would expect them to. It well might be my joystick as I’ve built my own so I wonder if anyone else see the same as me? If I move my joystick full aft and back to center, the outer rudders go up and down but doesn’t always follow the joystick movement, they can move full fwd or aft and fluctuate. They do this until I’m airborne and I’m wondering if it’s just an animation problem or if it’s how the joystick movement is actually output on the control surfaces? When I rotate for take off I always have to fight the aircraft for not over rotating and I wonder if it’s that the rudders doesn’t move with my joystick and kind of get stuck in aft position? I don’t get this nose up behavior when I’m airborne. /F

  6. Under the switch it says “Säk Avst”, that could be “Säkerhets Avstånd” and would be “Safe distance”. It also could be “Säkrings Avstånd” sort of ”Arming distance”
  7. That is a good argument! I would think that they made it the way it is to harmonize between all the different throttles being used by us?
  8. No I don’t think so, if they can fix the oscillation spot I don’t think anyone will have any issues with it really.
  9. The detent is there, what I meant was the detent is not a on/off switch between ground and flight idle. In DCS if you move the throttle slowly from ground to flight idle the rpm increase is very sudden, it should increase like when you move it in the flight idle to max Mil regime.
  10. I’ve had this too, there seem to be a sweet spot where this occur, and if you’re lucky enough you’ve set your flight idle at that spot ;) I adjusted the throttle curve slightly to get out of the spot where the oscillation occur. There shouldn’t be a ground idle vs flight idle spot, the throttle should increase thrust linearly. - The Mil thrust range is about 50% of the throttle range, last 50% is the AB zones. But I understand why it’s done the way it’s done, not many throttles have adjustable detents and there would be serious crying if the AB kicked in at 50% range of peoples throttles :)
  11. Yes, the charts I’ve seen show a max weight of 17 tons for Mil power take offs. Clean AC with x-tank weighs 16433kg, that doesn’t give much room for weapons. It show that on a day with 25C air temp, if your AB fails under 300kmph you will not have enough power for level flight. The aerodynamic compendiums and charts also say/show that if your approach speed is low compared to your landing weight you have very little room for corrections before the drag will overcome the thrust and you will have to use AB to recover. If I read it correct, the max weight for a 15.5 aoa landing is 14000kg when air temp is -30C, at +20 the max weight for 15.5 is 12.5-13000kg depending on air pressure, to have enough power to accelerate with full Mil power. 12 aoa, +20C max weight about 14kkg to be able to accelerate with full Mil.
  12. Roll center is on the left panel, under the three gauges (trim and what more)
  13. Ive updated post #2, red ones is the ones that doesnt work for me. Regards F
  14. I will try to show with an example, the Auto Yaw Trim: The AJS37.lua: definePotentiometer("AUTO_YAW_TRIM", 22, 3732, 211, {0, 1} The clickabledata.lua (AJS37): elements["PNT_211"] = default_axis_limited(_("Autopilot Yaw Trim"),devices.FLIGHTDATAUNIT, 3732, -666, 0.01, false, false, 1) So when i use the control reference: I expect to be able to set a value betwen 0-65535 and see the Auto Yaw Trim dial go to that position, but its not. It rotates, to me, totally random, ie if i set 24500 it can be rotated right or left and if i set the same value again it rotates again. In clickabledata it has -666 where most of the other has its argument number, dont know what -666 is. Im not sure what else i can add, it just doesnt work as it is. Best Regards F
