Unfortunately it appears this stick (that I also have owned for years) does not work well with FS2020. I tried to configure it and found that FS2020 has no facility to bind with the throttle 'axis' Instead it works like a toggle - increase or decrease in just the same way as pushing the keys on a keyboard. This make it really hard to control the aeroplane. There is no force feed back, but think that's known already due to a patent issue.
If anyone works out a solution to the throttle problem please let me know.
