Any news on the weird ground roll behavior?

@bobsk8 said in Any news on the weird ground roll behavior?:
What are pilots using to properly adjust the rudder trim prior to takeoff, in order to eliminate the need for excessive rudder input to keep the aircraft centered on the runway as the aircraft picks up speed prior to rotation?
Obviously it's difficult to look vertically down at the rudder trim indicator, so there is parallax error when viewing it from the pilot's position.
From my pilot position I know that the rudder trim is neutral when the white/silver mark inside the aperture is midway between the long centre marks and the short marks closest to me (hope that makes sense). Not a very accurate visual indication, I agree, but I also know what position the wear pattern on the knob should be in for neutral, which gives me a more accurate visual indication. If you have a key/button allocated to the Reset Rudder Trim command, you can use that to set it at neutral.
I don't touch the rudder trim before takeoff. Since installing the latest update (v0.10.3) I'm not experiencing any need for excessive rudder input to keep the aircraft on the runway centreline. Even with a 10 knot crosswind it's not too difficult to keep it on the centreline with rudder and aileron input.
As I understand it, the rudder trim and its indications are as per the real world aircraft that JF modelled their Arrow on. Is the rudder trim indication any better on the real life Warrior you fly? If so, maybe you could explain what is different?

@sender46 That did the trick. I used the reset rudder trim, and that seemed to work. Thanks.

Here is a video of how it currently stands:

Note that trim is neutral, flaps are up. I literally loaded the aircraft and went for a run! In that config, Vr is 70kts which is the highest rotation speed given in the POH. I held the aircraft's nosewheel on the ground until 100kts, at which point the aircraft lifted off by itself. Around 80kts there is a very slight wobble but very easily held with a touch of rudder and your nosewheel has no business being on the ground at that point anyway!
Hope that's acceptable.
@delta558 thank you. Preliminary testing since the update and the issue seems to have been fixed. Thank you.
I will let you know if it pops up again, but I am pretty sure it is fixed. I do need to fly the Arrow more to be sure.
