@sebastianr We are the devs - it was developed by Just Flight. If you submit a support ticket it can be logged. The more reports we have of something, the more we can piece together causes and solutions.
@anderson The ticket was resolved with the understanding that the issue has been passed to the dev team to investigate and that "A fix will likely be included in the next update to the Arrow III (for MSFS)", without an ETA. That's good enough for me.
@harry_w Nope, the only mod I have that only affects the Arrow is a replacement for the prop animation. I use the "standard" Working Title Garmin upgrades, a UI modification (just changing the style and size of aircraft nameplates), a couple of realism mods for default aircraft (DA40-NGX, DA62X, JPL 152, HPG A5, WT CRJ), a handful of purchased aircraft, and the rest is scenery. Nothing fancy.
No idea what's going on, and so far the performance issues have not returned, in spite of adding more and more add-ons with every MFS restart. Fortunately, I recently discovered the "MSFS Addons Linker", which makes enabling/disabling add-ons rather painless.
I made new images by doing a circular blur of the original prop texture in GIMP, front and back. I hated the VR wobble and the stroboscopic appearance of the prop. I just think it looks more real this way.
I ran them for a long time as just replacement textures, but finally figured out how to make a community folder package!
Thanks for the answer, it does not correspond with the problem I have, I have no crosswind problems (I did tests in the total absence of wind) mine is a problem of deadlift moment in takeoff and moment of landing gear touch. land in the landing, everything that happens immediately before is all right ..
unfortunately with Translate it is not clear when it advises to vary the steering angle or maybe I understood so myself .. can you give me some advice here? as it is now the plane is practically unusable ...
I believe after some testing I have managed to resolve the broken Pipers issue. I tried many things and nothing seemed to work and then it struck me that I hadn't switched to a compeletely different plane. So, I switched to the default Cessna (the original 172) and started a flight. I then put myself back in the Piper Arrow IV and all was, once again, right with the world. I just completed a 2hr flight to El Paso and it was a great flight!
I'd like to thank you all for your help and I hope the above notes serve to help another.
