Oh eck, that sounds a bit scary! I'll check it out later & see what I can do.
On the question of range,I was using the FSX one & with no tanks I was running on fumes as I lined up on final.Ctrl+Shift+F2 didn't seem to do much(maybe because I have auto-mixture engaged-I will need to check)I don't think I have altered the .cfg from the original.
