I will check the action type thing when I get back home.
The rudder pedals are the Slaw Viper RX which are supposed to be plug and play other than using the calibration program that comes with it and is supposed to be used rather than the windows calibration. I have been in touch via email with Slaw and he is adamant that these pedals are not the problem and that they will work completely in MSFS 2020. He says there are many of his customers who are using them with the flight sim.
I have unplugged all devices other than the mouse and keyboard from my computer and tried running the config with only mouse keyboard and rudder showing in MSFS.
Slaw swears the algorithm he used is not the problem even though he says it is similar to a mouse algorithm.
These worked last summer when I first installed MSFS. The difference now is that a very extensive update occurred when I started MSFS after an 8 month hiatus.
Edit; I will again delete all profiles, unplug the rudder, start MSFS and then plug the rudder cable in and see what happensâŠ.again.
OK, things are starting to come together. I will research the Slaw Viper RX (Iâve never heard of that make/model).
Update: Wow, nice pedals! The following has no bearing on what weâre trying to do here, but it is unfortunate news from the Slaw website:
As of today, March 18, 2023, orders for RH Rotor rudder pedals are still being accepted.
Production of these pedals will be suspended at the very least. The suspension of production will take place, at the latest - in May. But it may happen sooner.
Iâm sorry this happened. Unfortunately, we have no influence on the cost of parts for the production of rudder pedals.
Design of new devices and small-scale production will continue, at least I plan so.I will post any changes here.
Thank you for being with us.
Yes I learned that from Slaw yesterdayâŠthese Viper pedals are awesome, but I would really like to be able to stop the aircraft in MSFS.
Yes, stopping the aircraft is important! 
It would be nice if slaw had directions on how to install to MSFS.
Update: I hadnât realized until now that you have two threads going on the problem:
I see more of where youâre coming from now and why youâre so frustrated. Youâd think Slaw could give you some help here on how the pedals are to be installed in MSFS.
I guess an uninstall and reinstall IS your only option remaining. It seems all else has failed. Have you tried getting in touch with someone using Slaw pedals on this forum? Perhaps a title like âSlaw Pedal Installationâ or similar would get the attention of someone using the pedals.
Slaw doesnât have MSFS 2020 but says
If you have calibrated the pedals with such
programs or with Windows, delete this calibration (restore default
values). Then calibrate the pedals with our software. Video
instructions are available on our YouTube channel. Perhaps this is
the reason.
In any case, if the pedals work in other simulators and Windows
detects all three axes, then the problem is only and exclusive in
setting up the MSFS simulator. It is also possible that some other
axes in your controllers âinterceptâ the brake axes.
Pedals cannot work in one simulator, work in Windows and not work in another simulator due to the >>fault of the pedals.
I have done the calibration with his utility and not with the windows calibrationâŠbeen there⊠done that.
So with the supposed âplug and playâ function of these rudder pedals, I get this after deleting all profiles, opening up MSFS and then plugging in the USB cable directly to a 2.0 USB port on my mother board.
I think I got that message when I first set up my CH pedals as MSFS didnât have a profile preset for them at that time. Click Customize and see what happens.
OkâŠI figured it out finally. Yay!!
There are two sets of Brake assignments in the MSFS list of controlsâŠsee image
I was selecting Left and Right Brake (sans axis)
Changing to the Left Brake Axis and Right Brake Axis solved the problemâŠtoo many options that I never noticed before.
There are obviously subtle differences in the two.
Itâs obviously not really Plug and Play with MSFS.
Itâs working in the default 172âŠnow I need to test in the JF Piper Arrow.
Excellent!!
No joy in the Piper Arrow aircraftâŠno toe brakes in this add-on aircraft from Just FlightâŠ
Rudder works but no brakesâŠ
I will try some other default aircraft later.
Donât have the Piper Arrow so know nothing about it. But it must be recognizing the old profile and not the new one. Reconfigure (if possible) or reinstall to see what happens.
Hold my horsesâŠwhen testing it in the Piper I was looking directly at the pedals and looking for the animation movement and didnt try it while rolling.
Itâs a JF aircraft animation issue.
The brakes work when the aircraft is moving, JF just didnt bother with the animation of the toe brakes.
OK, makes sense. 
A reinstall âmightâ fix that.
Problem solved and I have to understand that not all components are animated in some add-on aircraft.
You know what they say about making assumptionsâŠ
No need for the toe brake animation really. Perhaps JF decided it wasnât worth the effort. Who really looks at that when flying?
It should be noted as a bug if it is not already, though.
I hope I was of some help to you. I know it took a while, but thatâs sometimes what happens, as you probably know.
You were of great help. It got me to looking at my errors in using the config options of MSFS, which I am still learning. I guess I could reach out to Just Flight to see if that is a bug or a âfeatureâ.
Thanks to you and everyone else who helped in getting me to understand how the config works.
