Rudder problem

[j0nx]

The rudder axis on my mi24 seem to have a mind of its own. The pedals start centered at beginning of flight and then quickly start moving left and right on their own back and forth. Doesn't matter which device I use for my rudder axis it is the same behavior with all of them. I do not have any conflicts and I have unplugged all unnecessary controls when trying this. This is the only aircraft that has this problem. It's almost as if AI is controlling the machine. It's been a few months since I have flown this bird so it could be any number of updates that broke it. I already reset/cleared all controls on the mi24 and rebound them but it didn't fix it. Any suggestions?

Your yaw autopilot is in heading hold and auto trimming your axis to maintain heading. There are lots of threads on this and I have written everything you need on this in my autopilot guide https://drive.google.com/file/d/1gAQcRMO6SqMA6LyrbLr5wnMhboVJASV_/view?usp=drivesdk

To fix it you need to either turn off the Yaw autopilot channel, or have your MicroSwitch on so that the yaw channel is in dampening mode rather then heading hold. You can do this by having your pedals deflected from center a certain amount like in Mi-8 (but does not work as well becuase of the tail changing the center point throughout flight, and the speed of auto trimming being much faster), or by having the “Y” keyboard button which is bound to the MicroSwitch, which are switches in the pedals that when pressed by the feet make yaw autopilot stop holding heading and trimming you and only make the yaw autopilot dampen you. 

The part you want to read is Section B Part 1 and 2. I also wrote a weapons guide that explains peculiarities of the weapon system and certian weapons and how to best employ them. I tried to make it avoid procedures you can find easily in chucks guide or tutorials, and focus on best employment tactics. https://forum.dcs.world/topic/294627-personal-mi-24p-autopilot-and-weapons-guides/

Resetting the cyclic trimmer stops it as long as the yaw AP is disabled. This must be new behavior because I never had to do that before. Cool feature though and takes the workload off the pilot in hovers for sure. Does the real mi24 do this?

The real Mi-24, when yaw AP is on and microswitches on pedals released, will use the hydraulic cylcinder in the pedals to move them to 100% of their authority, only after the 18% of the AP authority is used up. 

Feet on the pedals/switches pressed, it will be in dampening and only fight changes in rate of movement. 

Real Mi-24 does this, but it is not as invisible in DCS as it is in real life when we don’t have buttons on our pedals 

Resetting trim will also work with Yaw AP on as long as microswitches are pressed and YAW AP in dampening mode
