Hi Gunner,
Great. So much of FG is controlled by XML files that it's really useful to know how XML works. u
No idea where js_demo will have gotten to - it should be somewhere like D:\Program Files\FlightGear 2017.3\bin\win32\ or D:\Program Files\FlightGear 2017.3\bin\.
Put the configuration file in D:/Program Files/FlightGear 2017.3/Data/Input/Joysticks/CH/, and then remove the equivalent file from C:/users/gunner/AppData/Roaming/flightgear.org /input/joysticks/. Make sure to use a <name> element so it gets picked up.
BTW - CH Products are kindly sending my a throttle so I can write a configuration file. It will hopefully arrive tomorrow, so I'll be able to work on a config file over the weekend.
