Uncontrollable yawing to left - Resolved, Thrustmaster t16000m fcs needs reliable 5V supply to avoid this.

[RAS Zodiac]

Hello everyone,
Been playing computer games for over 35 years and this is my first post on any forum! I've played X2 Reunion, X3TC and now X4 Foundations which I bought on Steam in March 2021. Because I bought a new PC and a room refurb I've only just started playing from the Young Guns start. My issue is with the uncontrollable yawing/drifting to the left in flight. I have a Thrustmaster T160000M HOTAS and no matter how I assign 'Primary flight control' to my Z (joystick twist) yaw/rudder, turn off the gamepad or set it to controller/joystick it persists.
I currently have the left/right set to a digital input which makes combat very difficult.
I appreciate this is an old issue but I'm at my wits end with this. I've played Elite Dangerous with the exact same setting with no issue.
Thanks.

It could be all sorts of things such as where the game expects an analogue input but receives a digital one instead - or vice versa. The game has the choice of digital and analogue input options in the Controls profile for at least 2 axes. Check your stick output settings against your game settings and against what you intended in that respect. You may not have all control options over all 3 axes and so might have to compromise a bit on one of them.

Sometimes other game settings such as flight assist and auto-roll can have strange apparent effects on controller/stick outputs so that may be worth checking.

Other causes could include poor stick calibration, poor deadzones, poor sensitivity settings, or a stuck controller button or throttle that is sending a continuous input to the game.

Make sure that a different controller that is plugged in is not overrriding your stick outputs. It is best to unplug any controllers/sticks etc that you don't need while playing.

Good luck with the investigation.

If steam version go in ur library right click on x4 go to properties then find controller then click on the use default settings line and change it to disable steam input. See if that helps.

If using a 360 pad and a stick, maybe unplug the pad while playing with the flight stick setup.

Hello, thanks for all your suggestions and help but the problem persists.

I only have my Thrustmaster t16000m and twcs throttle plugged in and I've downloaded the latest drivers for it. In Windows control panel everything seems to be working including the joystick RZ rotation and I've never seen an option to change between digital/analogue signal in here. In game however something is sending a signal to this axis causing the yawing left. I've mapped left/right to a digital input but not ideal.

Hi everyone, just thought I'd update you on my issue.

While trawling the internet/forums i stumbled on a post which was the answer. Apparently the thrustmaster t16000m fcs needs a permanent and guaranteed 5v power supply. Plugged into my new PC, in any of the 7 usb ports, didn't do this so I bought one from Amazon and now everything works flawlessly.

You live and learn!

Thanks for the update and resolution.

It makes one wonder what else a possibly suspect 5V supply on one's system might affect though.

You don't happen to remember where you read this?

/me Thinking about opening the joystick and measuring voltages before and after regulators.

Windows 10 power management will turn the dormant controller off, to save power. You can disable this in the registry, I used the following the guide so I could use two TH16000M's, without Windows constantly turning them off.

@ peteran: It occurs to me that the stick internal regulators must be doing their job properly if the stick works fine with an external 5V supply but not necessarily with the OP's system supply.

Now I'm curious. Does the T.1600M really draw so little power that it gets to the realm of parasitic? At least one of my power banks shuts off the power just as my Raspberry Pi Zero has booted. Windows shutting off power sounds like the most likely reason.

• Did this happen on a laptop or a desktop with laptopish power settings?
• Check USB selective suspend in Windows power options.
• What version of Windows?
