This has happened to me just recently as well. Only for the FW/Piaggio P149 and the Jabiru aircraft. All others seem fine. I cannot seem to remap and get them to work. It is just the throttle only. The prop and mix work just fine. In fact if I use the mouse to manipulate the throttle in the P149 for example and then touch the throttle lever on my Saitek, it cuts the engine back to idle. If I load any other aircraft before or after one of these, it all works as planned. Uninstalling and reinstalling the aircraft has no effect either. I am also not running ANY mods.
The switch panel has odd things happen when switching the lights and taxi lights on/off a number of aircraft both default third party when they didn’t before.
I am hoping the next update might help magically. Though it could be from a windows update or NVIDIA driver update? I may have to use SPAD.neXt to see if that helps. (Really didn’t want to have to)
Logitech Pro yoke, throttle, panels
Thrustmaster rudders
Similar system but Windows version, no mods not beta or using dev mode
