Jring2,
Thanks for the good words, I'll be sure to pass them along to all of those that have helped and contributed on the project.
Now for the "meat and potatoes" of the discussion.... Two things come to mind: 1. Not sure which version you have of the 16.1 (there are many...), but the Rolling Surface to Rudder Interconnect (RSRI), might still be enabled on your jet, or 2. The rudder PID needs to be adjusted.
RSRI TESTING
Easy way to test this:
-Get in FSX and load the jet.
-Press Shift + 8 to bring up the Data Gauge (if nothing shows up, grab a test or prototype jet)
-Get in the air, slow down to the problem airspeed and look for the RUDDER TRIM entry on the Data Gauge. If you notice that rudder trim is moving every time you apply lateral stick (ailerons), then I'm thinking the RSRI is to blame. I've since disabled it in later versions of the aircraft.
-So...if the RSRI is active, you have two options:
1. You can open the aircraft.cfg and change the value listed next to the "rudder_trim_effectiveness" entry. For starters, I'd recommend changing the entry listed to "0", thereby rendering any controlling authority that the rudder trim had on the aircraft to zero. If this does fix your issue, I'd recommend putting the original value back in for "rudder_trim_effectiveness" and proceed to 2. That way you can still utilize rudder trim later should you need it.
2. Other option is to disable the RSRI gauge by going to the primary aircraft Panel file, open the panel.cfg, and edit out the RSRI by adding two slashed out in front (//) of the entry. Save and reload the sim and reload the aircraft.
-If that was the culprit, then it should fix your issue.
PID TESTING
The other problem, might lie within the Rudder Proportional Integral Derivative device or "PID" for short.
To test this, do the following:
-Go to the aircraft.cfg file and luck for the "FCS" section.
-Find the "sideslip" entry and trying lowering the first value significantly. Save and reload the sim/aircraft and give it a go.
-Once the ill effects to subsided, gradually increase the first value until you get accurate turn coordination with the rudder, without the wagging.
Hope this helps.
Have a question for you. Are you running the latest version of P3D? Are all of the avionics functioning for your jet? Although my screens show up, they are not functioning. The compass rose doesn't rotate; all of the engine data parameters are readying 0. Are you getting the same indications? Thanks.
