I'm free for the rest of the day now so I should be able to help out on Discord, Susie...but I suspect most of the problems you're having is through importing other peple's bindings or HOTAS mappings in then trying to edit those using the control menu.After 4 Days of trying to get my throttle working in SC I'm stumped (and totally frustrated). If anyone is using a thrustmaster T16000M FCS hotas and has a working mapping profile they can send me - please do! I've tried an old profile from the Spectrum forum and the Warthog profile. Neither solve the problem. It is either 0% or 100% but nothing in between.
If you import a custom HOTAS/keymap, you must select that profile from the built in profiles that appear in the SC keybinding options and edit those settings, using the menu just edits the default settings which the custom bindings then override.
What I've found is that it's much better to set your own bindings from scratch using the mess of a controls section (through trial and error), delete all the custom bindings and use your own...there's no conflicts between custom bindings and the default then. Once you've setup your HOTAS via the default controls menu, it's simply a matter of copy/pasting the profile folder over to a new patch or if you delete the user folder.
I'll pop on Discord in a few minutes
