Can confirm this issue. Applying "mouse vertical down" to "cyclic backward" is broken. This is a must have for inverted flight controls.

I also have difficulty binding "D" to "Cyclic Backward." it simply doesn't work. Strangely, I could bind it to "C" with no problem.

I also had this problem my non-functioning keys were the vertical mouse movement and the down arrow key, I solved the problem by resetting all the keys

Even after resetting all the key binds, I still can't use "D" for "Cyclic Backward."

I’m currently having a similar issue on xbox. Pushing back on the left stick (the default setting) won’t do cyclic backwards like it is supposed to. I can’t seem to fix it

I'm having the same issue, I can't use mouse vertical down as cyclic back. Didn't realize this ticket was here before I opened my ticket. All the PC players on my server are nose diving into the ground all day xD

I have potential fix for PC users.

Just like in the video provided by @geooperbob cyclic movement was still detected despite no provided keybindings. I tried to resetting all the keys, with no luck. What worked for me was deleting profile directory located in: C:\users\user\Documents\My Games\ArmaReforger\ or simply in: Documents\My Games\ArmaReforger\.

Just in case backup this directory before deleting, and yes it will restart all settings.

I can delete my saved arma data on xbox. from what I know, it deletes my mods, but also may fix the settings. i’ll try and and hope it works

unfortunately, it didn’t. it seems like very few fly on xbox, and even fewer have this bug, so i’m most likely going to have to deal with this issue on my own

I was able to fix this issue on PC by deleting InputUserSettings.conf in C:\Users\[yournamehere]\Documents\My Games\ArmaReforger\profile\.save\settings which resets your binds but fixes the cyclic issue
