Any news on the weird ground roll behavior?

@pepe_fr it is very much like the issues with stock planes when MSFS first released. Just… if anything it feels even more exaggerated than that was.
And yes, cross winds do seem to exaggerate this issue. One way to quell It is to fly without weather. It does help things.
I am optimistic the next patch will address this. The video posted above looks great!
I got this Arrow as a trainer. Take off and landing practice. Touch and go.
Just Flight makes brilliant planes but this bugaboo keeps me from using the Arrow III as I intend to use it. And it isn’t a cheap add on!
Anyway, I am not new to sims. I know how it goes. 3rd party devs need to keep up with changes to the sim. Bugs and quirks happen. Sometimes you need to keep a favorite plane in your hangar for a while as it waits for patching (repairs). It isn’t a big deal in the grand scheme of things, but it is enough to keep the plane from being useful to me as I intended to use it. There is still fun to be had with it. And if anything, it has encouraged me to learn the Turbo in the interim, which is an acceptable consolation.
I trust Just Flight. I like what they strive to achieve. And there will always be bugs to quell, even for the best devs.

The Arrow III seems to get it all at once around 70 MPH. Like it is hit with a microburst of wind before a thunderstorm. Or like a rear tire blew and pulls it in a direction. Everything is going fine and then HOLY S***!!!
This has been my (disappointing) experience exactly with the Arrow III. The first time I went to take off it happened, and my first thought was "did I just blow the right tire?"
I had not experienced any handling that wild outside some of the warbirds and even with those I was quickly able to get accustomed to their characteristics and was able to compensate. With the Arrow III the only thing I've been able to do to tame it on the ground is turn on auto rudder. Otherwise, it just inevitably turns into Tokyo Drift.

@apocv I haven't flown the Arrow in quite awhile, and I had a takeoff today that was beyond wild. I was headed for the side of the runway with full rudder opposite the swerve. I then experimented with the rudder trim, and got it where it was fairly under control. The downside of that is there is no way to read the rudder trim setting prior to takeoff. The other issue is the poor stability in pitch that this aircraft has. You trim for an airspeed, and then it roller coasters if it feels like it. I am done flying this Arrow, not enjoyable at all.

@derek I suggested @bobsk8 post here from the Avsim MSFS forums, he's obviously having a very bad experience with the Arrow which seems fairly unique. I'd like to know the answer to your question regarding the flight model but if that's 'modern' we should look more. If the latest patch has been installed, there's no way the 'swerve' should still be there -I've held it on the ground in a straight line to 100kts, well above maximum rotation speed even at the heaviest weights.

He really should contact Just Flight support, rather than post in the forum. There is much discussion about our products here, but I would say he is describing something that doesn't work. Given the number of copies successfully buzzing around out there (eg https://www.youtube.com/watch?v=u8KLF986GNg ) it may be a local problem that Support can help with.

@derek I have a question that should be able to be answered on a forum post. I have played around with the takeoff directional control for a couple of days, and BTW I have about 60 hours real life in a Piper Warrior, so I am fairly familiar how this Arrow should handle on the ground. I have determined that the directional rudder control is very influenced by the rudder trim adjustment. A tad one way or the other with rudder trim causes the aircraft to veer to the left or right excessively as takeoff speed increases.
Now my question is this, how does one set the rudder trim prior to takeoff. I see there is some kind of indicator , a line, that moves when the trim wheel is turned, but there is no way to see what the actual pitch is when adjusting it, for example, 5 degrees right or 3 degrees left, or neutral. 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?

@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.
