Default Uncommanded Left Rudder During Flight

Since Update 9 I have had uncommanded left rudder during flight in the Yak-52, and only the Yak-52. Cleanup/Repair has not resolved the issue. My controllers are calibrated and working properly. Takeoff Assistance and those other "cheats" in the Special tab are all off. Attached is a track and a couple pictures.

In the first picture, you can see that the Controls Indicator is showing rudder slightly left of neutral, while the DCS axis settings are showing my actual input of right rudder. Note my axis is not inverted.

In the second picture, you can see that the Controls Indicator is still showing left rudder, while the DCS axis settings are showing my actual rudder position as neutral.

This only appears to occur in the air. When on the ground rudder inputs are exactly as they should be.

My guess is that the ground adjustable trim tab for the rudder has been added, and it starts moving your rudder as dynamic pressure increases, hence not being noticeable while on ground, taxiing or any under circumstances where propwash or airflow aren't suficient to make the tiem become alive...

That seems plausible. I noticed that the degree of the uncommanded left rudder decreases as I slow down after landing/increases as I increase speed on the takeoff roll.

Is there any way to turn this off?

Maybe in the future they'll add a way to adjust the trim tabs in the settings, like we have for the Bf 109, but otoh, this is a realistic feature - the real aircraft reacts the same way, unless the pilot counters the tendency of the rudder to deflect, but he'sw bnot supposed to do so because these settings are calculated for cruise, and to avoid the need for rudder input under such circumstances.


It's a realistic feature, not a bug :-)

I'm confused as well. There is an "auto rudder" option in the Special tab, but this left rudder input that I get happens regardless of whether that setting is on or off.

Then that probably is the cruise rudder settings working now. The auto rudder box should be takeoff help if i am not mistaken.

I have all of that stuff off, so I don't understand why it's being affected. I'd really like to turn this feature off as it makes flying a bit more difficult. Left turns require neutral rudder and right turns require excessive right rudder. It feels very unnatural.

Hmm interesting. I have Auto rudder OFF and have tried the Rudder trim setting in the settings screen Full left and Full right. Doesn't seem to have any actual affect.


In game though do a take off with Control position indicator up. Before Power application Rudder Pedals central as is Rudder position indicator. As you advance power (pedals central) the Rudder position indicator moves to the left.


In flight the requirement for right rudder to keep balanced at the higher airspeeds is good. However there is virtually no requirement for any Left rudder at Low speeds (130-160Kmh) power 800/82%

Latest FM is still not correct for rudder and is actually less accurate than before I think.

Next to no left rudder required on T/O is inaccurate, real plane requires substantial left rudder through about 170 KPH, tailing off to neutral around 200-220 kph, and then shifting to right rudder as speed increases such that substantial right rudder required above 270-ish kph.

Not uncommon to use several inches of pedal travel between left/right extremes when flying a loop or quarter clover.
