Sorry for the delay replying. I’ve been away for a few days.
I managed to get it working, but by amending the axismapping.dat file using Notepad, to try to assign axes to the Orion throttle and stick.
It didn’t work straight away, when I went into “Controls” I still needed to reassign them in Advanced, but this time it retained that information rather than deleting it when I changed from Stick to Throttle in “controls”.
If it doess it again, I will try the procedure above - but I don’t want to risk changing anything at the moment while it is working ok!
