Yes, that makes sense indeed - and in IRC yesterday and with the help of Melchior, we found the solution. For some reason, although when I plug in my JS it all reads 'spot on' it really isn't. Running jscal and calibrating the JS then makes it all work perfectly in js_demo and FG. So perhaps as nothing has used the JS when I plug it in, it doesn't show up as being out of calibration. I also stated that it doesn't affect FG - well, I lied :-) It did do and I didn't notice. I was always fighting the JS a little in keeping the aircraft straight/level etc., but now it is not so imposing and I can fly better with less effect! Also, by using the -p option of jscal, it produces commandline data that can be read back with the -s option, so all I need do is run that little script at startx (or when I plug my JS in) for it to be sorted. So resolved! Thanks for interest and help.
