IL-2 Joystick curve

Even better, you could have profiles for single and multi engine aircraft if you have dual throttles. For example, in a single engined aircraft you could have one of the levers function as prop pitch, but in a twin you could have both levers functioning as separate throttles with rotaries being used to control prop pitch for each engine.

I'm not 100% sure but i think it's actually going to be in the upcoming 4.10 version.

Well if it is in next patch then we only have between now and forever to wait ... if its in a future patch we may as well expect to be playing the new SoW

I am using the standard version of Saitek X-52. The non-pro version does not offer adjustable input curves, and the default curve produced by the joystick is actually non-linear but exponential for pitch and yaw - a design feature that I can not really understand.

I personally would love to fly with fully linear control settings for pitch and yaw - and if I had rudder pedals, that too - on twist handle, linear response for rudder is untenable.

Getting the control response to feel linear (or close to - there's actually a slight logarithmic decrease in my settings toward the middle) requires a bit of trickery, though:

[rts_joystick]
1X=0 133 148 146 144 133 123 115 109 104 100 0
1Y=0 133 148 146 144 133 123 115 109 104 100 0
1Z=0 100 100 100 100 100 100 100 100 100 100 0
1RX=0 100 100 100 100 100 100 100 100 100 100 0
1RY=0 100 100 100 100 100 100 100 100 100 100 0
1RZ=0 10 20 30 40 50 60 70 80 90 100 0
1U=0 100 100 100 100 100 100 100 100 100 100 0
1V=0 100 100 100 100 100 100 100 100 100 100 0
FF=0

1X is pitch, 1Y is roll and 1RZ is yaw.

As you can see, I manually entered these values into conf.ini, because the in-game interface didn't accept values larger than 100. This setup increases the sensitivity of the stick's by default "limp" center area, bringing it closer to linear response, while keeping the area immediately next to deadzone slightly less sensitive than linear (but more sensitive than the default curve of the stick).

As far as I can tell, the default control curves for pitch and yaw on this stick correspond with these settings used with a linear control curve joystick:

1X=0 1 4 9 16 25 36 49 64 81 100 0

If I now want a completely linear output from these inputs, I would want to insert these values in the conf.ini:

1X=0 199 180 163 148 135 124 115 108 103 100 0

in other words

1X=0 (100 + 10^2 - 1) (100 + 9^2 - 1) (100 + 8^2 - 1) ... (100 + 2^2 - 1) (100 + 1^2 - 1)

This will cause the Saitek X52 with it's non-linear control curve to behave as a linear control curve in IL-2.


With my earlier stick, a Saitek Cyborg Evo with linear control curve, I used pretty much the following curves for pitch and yaw:

1X=0 33 66 82 95 97 98 99 100 100 100 0

and the current curve is basically this, but adjusted for the strange actual input curve of the X-52.


I hope someone can find this post useful for setting up their X-52 for IL-2.

It's probably just me, but do you mean pitch and yaw or pitch and roll?

I didn't know that could be done. Are the numbers you put into the conf.ini then seen in-game or do they still peak at 100?

Yep.

Never really understood why people go, 'yeah, 100s all the way, that's how to fly'.

Depends on stick, depends on flier.

MSFFB2 and CH sticks are utterly different in feel and throw length, for example. As long as you can hold the bead steady on an engine, and don't spin out in turns, then you're right.

Interesting post, since I got the same stick.
Q:
- curves: Well, can't we use the pro software then?
- non linear: How do you know?

will try thx.

It does, you have to check the ">100" box.

What I ended up doing was pulling all the in-game Yaw sliders down to 0, and in the Logitech Gaming Software moving the rudder pedal sensitivity down to 25%. This means I really have to kick the pedals to make them move in a big way, but I don't see that in itself as a bad thing, as I don't think Yawing needs to be as responsive as Pitching or Rolling, and the lack of responsiveness has the advantage of allowing me to make more subtle adjustments.

There is still some oscillating or bouncing backwards and forwards as the pedals are moved quickly backwards and forwards, but that seems realistic to me so I'll just put up with it.

With those settings though I found it easier to aim at ground objects, and when on an enemies six it was easier to aim at a certain point on their plane or strafe them from wing-tip to wing-tip. I also found on one plane I was testing with that I could kick the rudder in to compensate for the yawing induced by firing my guns.

Another thing in favour of reducing the rudder pedals sensitivity, is that it makes it easier to avoid using them to put myself into a spin when in a tight turn. I used to use a MSFFB2 twisty stick and the force feedback would shudder just as I was about to stall, so I always knew when to back off. But the G940 starts to shudder well before that point and can't be used the same way, so I find it important to not have the rudder be so sensitive at that point.

Anyway, just thought I'd suggest those rudder settings. I'll have to go back and see if all these first impressions I got of them are accurate, but I think they are. Now it's just a matter of remembering the rudder pedals are actually there in the first place. Never having used them (or a separate throttle) before takes some getting used to.

Incidentally, in the Logitech Gaming Software I've currently got Overall Effect Strength at 100%, Spring and Damper at 75%, with no Centering on.

Hey thanks! I'll try that out. I have overall effect strength at 50, spring and damper at 40. Centering spring is on and 40%.

80%, btw, does make sense for newbies - helps a lot.

Yeah, with the default settings you only have to move the stick like 3/4 of an inch and you get a fast aileron roll, in a real warbird of this era you would be moving the stick close to full deflection, same goes for pitch and yaw.

[albx]

Well, after some more testing i was wrong, all 100 is way toooooo sensitive at the center, so modified my curve, and right now i found a good setting like that

1X=0 40 54 63 69 77 82 87 91 96 100 0
1Y=0 40 54 63 69 77 82 87 91 96 100 0

still tuning to find a better response...

We had a misunderstanding here.

I thought you were saying, that by the ability to adjust the stick sensitivity, some ppl can make their planes behave like F16s.

I thought this was a silly topic until I started playing with the 190 last night . The roll rate compared to planes I had been flying REALLY threw me off. I chose to just learn to adapt to the plane rather than change my joystick settings, but I could see someone having a special setting for each plane thus utilizing the hardware to make the adjustment.
