Plane swerving without any input !

Okey, so this has been happening for a long time. I've noticed it on all aircraft I fly with (F-15, A-10C, Su-33, Su-25 and more). Without any joystick (axis) input, the plane swerves to the left (in no wind conditions) I am sure there are no axis input and my joystick is working properly, because I can see it on the in-game axis display thingie (Rcntrl + Enter) that it is centered without any jiggling, and also you can visually see that the wheel is centered.

I always fly with balanced loads. At first I thought that I might be the offset on the A-10's front wheel causing it or the dis balanced internal fuel storage on the F-15, but this is happening on every aircraft and it is most noticeable on landing under breaking, sometimes you cannot even control it and you end up sideways on the grass. Even the Su-33 has it with its flight model and the way it sticks to the ground.

Is this a known bug or is it something only I experience ?

Reset joystick? Reset trim 'LCTRL -T'?

swerving=rolling?

Here is a quick example. Very noticeable ! I do a clean braking first then I have to correct the plane's course and then I do breaking with a nose pushed down (which I do normally when flying the 15 to decrease my stopping distance, on other planes I don't even need to do nose pushing to achieve such a great effect of deviation). And at the end again clean breaking with the same result. At low speeds it is not noticeable. Same is happening on take-offs.

Mission had no wind at +20 C

Here is a A-10C take-off and landing and again take-off.

First take-off with steering engaged till 70 knots you can see it clearly pulls to the left when steering is disengaged it starts pulling to the right but it is more noticeable on the second take off where I start rolling with steering disengaged on purpose and it clearly pulls to the right and when I engage it at around 70 it starts pulling left.

On the landing with steering disengaged it seems it rolls straight or with just a little deviation. When steering is engaged it pulls left once more.

Ow yeah, I forgot to mention I even have a slight dead zone on my rudder axis for my stick so I think it really it is not from my stick. But if I really have to I will try it without a plugged stick

Here are a F-15 Take off and a Su-25 T&L. You can see on the graph and on the external view that everything is centered.

Have you tried using Right CTRL + Enter to show the little inputs window and see if there is any weird inputs being made?

I have said that I am using it even in the first post. I use it in all the tracks as well. I use it all the time when I fly. Please, read :)

Here is the track without Brakes being used. At first touch there is no deviation, but once the speed gets low enough it starts pulling.

BTW I am attaching the mission I generated for this if you wanna test something on it.

Very unusual, I've never had this happen to me or heard of anyone else having the same issue.

I'd put money on your controls causing this, it has to be something like that, try it without your stick connected.

The only other way this could happen is if your applying the brakes to one side only and I'm not sure if this is possible in the F-15 at the moment (may be wrong).

It's certainly not a 'bug' with the game / aircraft, like I said I've never seen or heard of this before mate, my money is on your joystick!

Are both toe breaks inverted or only the right break? Only thing I can think of....

Cannot be that, because I don't have any pedals so I am using the W key for braking which means equal pressure. And it happens on all the planes. Has happened before on old installs as well. And you can see it happens on the track where I apply no brakes.

I will give the no joystick thing a try.

SHaDoW STeP BG try this.

I like that you have put the effort to type my whole forums name with every capital letter where it should be. :D Just call me Shadow (my DCS name)

Trim trim trim...... trim

I am not using Trim on purpose for the test. And when on the ground I put no joystick input what so ever :D

BTW is everyone just checking the first F-15 demo ? It happens on the other planes as well. Particularly interesting on the A-10 where with Steering engaged it goes left and with steering disengaged it goes right (where it should cuz of the offset on the front wheel)

Okey, here it is the track with no Joystick

It definitely felt as if there was less pull, but it was still there and still quite a lot, especially on braking. Nowhere near what BigNewy showed on his track or should I say nowhere close to what he showed.

To be honest it took my 2 tries to do the landing with the keyboard :P I came a bit too hard on the first attempt :D

FWIW, I also experience something similar, when braking ("W" key). Even a short, quick key press will start the aircraft wandering. I've never given much thought to it, though, because the "wandering" was controllable.

It does happen even without braking :) watch the tracks

is the runway completely level :-)
