This is an important issue, because when you map both controls (standard left+right AND analog left+right) to the gamepad, it will make the steering of cars really clunky, since the inputs interfere with each other.

So at the moment, you can either:
-use your gamepad for cars only (which would be a shame, because the gamepad was made for controlling vehicles in ArmA)
-or don't use analog steering at all (but it works so much better!)
-or change your configuration every time you use another vehicle (nope!)

helio//but not using analog steering is strange at high speed,really hard to steer.BI should fix it

I know, I share your opinion.
I really prefer the analog steering, too! So I hope they can fix it soon.

This is a bit pants tbh. I thought I was going mad and not mapping things correctly for a while.

Edit: The Marshal works fine where as the Slammer does not. It must be just specific vehicles that don't work rather than cars v. armor.

It's wheels vs chains / naval. :)

Oh right that makes sense. Thanks. Look on the bright side stuff like this is making me squeeze even more value from arma2.

By chains you mean tracks Helio? :-)

joostSidy//yeah,kind of that

Yes, please fix this. I am using HOTAS controls for flying and driving whenever possible. All wheeled vehicles steer fine with analog controllers using car left/right analog. Arma 2 worked fine for wheels or tracks, but Arma 3 treats them differently. Apparently boats, too, though I hadn't tried them yet. Arma 3 doesn't allow analog steering of tracked vehicles with car left/right analog. Presently I have to use mouse and keyboard - car left/right with keyboard and care more left/right with mouse.
