    This is not the problem, however the arrow flight model is tuned the MSFD weathervane effect on the tail is dramatically more severe than other aircraft in the sim both default and 3rd party, in a stiff crosswind you frequently cannot even keep it on the runway with full rudder input. Please assure us this defect is in-work, I think anyone at JF flying the arrow for testing in a solid crosswind during takeoff roll cannot deny what is going on.

    @sluflyer06 What kind of "stiff" crosswind are we talking about here? According to the interwebs, it seems that the Piper should not expected to take off safely in more than 17 knots crosswind.
    Not saying it's not twitchy, I'd love for it to be easier to keep in the middle!

    Something there is different with C152, with it I have no problems, does it wind or not. But with this I'll always lose plane control on takeoff / landing.

    I was just trying take offs and landings in a 20 knot cross wind in the Arrow III. You need to use timely and appropriate rudder input and proper aileron deflection, but its not that far off from real life and doable. (Skip to 4:50 for an explanation of what I'm talking about regarding the use of ailerons in a cross wind takeoff. Video here.

    I do find the rapid changes in direction of the aircraft from the weathervane effect as it approaches flying speed to be excessive. I have not done this in a stock MSFS aircraft, but I suspect its a sim issue and not a JF Arrow III issue. In reality, mishandling a crosswind takeoff tends to result at fist in a slow departure from the centerline that gets worse as you accelerate and approach flying speed. You need to make corrections early and with authority otherwise things will get out of hand quickly. Proper use of ailerons substantially reduces the amount of rudder needed for a crosswind takeoff or the rollout after a crosswind landing. I think the model underestimates the effectiveness of aileron in this case.

    I have the exact same issue. The yaw is overly sensitive and almost impossible to control the plane when landing or taking off. It will sway wildly between left and right (not in a normal way, it works fine for other aircraft in msfs). I have flight model on "modern".

    Same issue here, it just want to roll left slightly the entire time in the air, my flight system is set to modern too :\

    We are seeing the same rudder kick during mild crosswinds. Modern flight model selected as well, don't have the problem in any other aircraft.

    @pdd set up a seperate controls profile for the arrow and adjust your sensitivity curves. I find the arrow to be much better than defaults asobo aircraft but the curves are different.

    Just got the Arrow 3 last week and love it but I too am having this problem with realism setting to Modern. Landing is also difficult and the aircraft seems to porpoise a bit while on short final. Tried adjusting my controller sensitivity settings to no avail. I am a PPL SEL and have about 10 hours in a PA-28140B which is my closest real world experience but the 140B sure doesn't act like that!

    Hello I thought that agvec the last update the problem would be corrected ( or in part) but it is not the case and when cutting is very difficult to hold the axis of the track In these conditions I do not believe that I would buy the turbo IV

    @christian Assuming you are referring to the PA28 Arrow III I see the same issue.

    Hello all, I 'll have got the 0.40a version, I'm on modern mode and I'm unable to take-off with the aircraft. Just for the information, I'hadn't install the MSFS in the default repertory, I used a repertory on a SSD.
    And I've the same problem with another payware aircraft (TB20)and unfortunatly no trouble with free aircraft or usal MSFS Aircraft. I've all installed in Admin mode, MSFS is launched in admin too

    Just my two pence

    I don't have this issue, so I find it very difficult to resolve it.

    I have made adjustments which I hoped would help, but as none of the testing team have reported suffering with it either, it's not just a simple case of make an adjustment, test it and it's fixed!

    The fact that the problem has been seen in another payware aircraft (which is nothing to do with us) suggests it's a common problem, and may well be to do with the way the sim understands certain elements of the flight model, but once again the SDK is so lacking in any detail or conformity to standard aerodynamic reference that it has been a struggle to get the aircraft to where it currently is.

    Imagine you are asked to direct me down the street, I'm blindfolded, you are in your house and have no idea what my street looks like. Might sound a bit flippant but that is the reality of what we are dealing with here unfortunately.

    I just tried 5 different crosswind takeoffs at KABQ and a nasty one at Wasserkuppe in Germany with live weather and winds exceeding the piper's demonstrated and still had no problem staying on the centerline. I'd say it seems to be doing pretty well.

    For those having the problem, it appears that it also affects some of the default aircraft :

    https://forums.flightsimulator.com/t/a320-a321-and-a330-pulling-to-the-right-on-takeoff/399076/26

    The OPs post within there describes a hard pull to the right as speed builds, which sounds very familiar. I'd suggest keeping an eye on that thread as it develops, if a clear solution arises by all means drop me a pm here and I'll look at implimenting it but for now I can't keep chasing invisible / core flight model problems, or the Turbo Arrow will never get done...

    Same problem here, straight until I hit around 50 knots then boom, uncontrollable and need major rudder pressure to compensate...have similar problem with the spitfire. Using both honeycomb devices and saitek rudder. tried all the settings proposed with no success....asked for refund the day I bought it, Just Flight told me to make sure I update to the latest release....I understand that it's not behaving the same for everyone but a lot of people complaining about it, they should grant the refund , especially on the same day. Really disappointed :(

    @jeerouss This is almost certainly down to MSFS itself, and not any of the aircraft either stock or third-party. The Asobo team are making changes all the time and right now the flight model is incredibly unpredictable from one update to the next. Both users and developers are waiting ( hoping ) that things will settle down soon.
