Hi Danny,
But now one last problem/question. How do I fire the guns? I found the masterswitch, but there is no responce to '.' or trigger on joystick. In controls there is nothing related to firing weapons either.
do you have rudder pedals?
Can you brake your Sabre when pressing '.'?
Try this: Go to the 2nd page of the status panel and press '.' or press the joystick fire button. The line "Brakes:" should display the brake percentage. To fire the guns you must reach more than 50%.
Click into the brake percentage (tooltip should read: "Click for brake axis set"). This may help to reconfigure.
An other possibility is, that the guns actually do fire but you don't hear the gun fire sound nor see the tracer bullets, ie. because you haven't installed the gauge sounds and/or the effect files. You can confirm if the guns are firing or not when watching the "Ammunition:" line on the status. That number should decrement to zero if the guns are firing. Btw, apart from setting the master armament switch to ON position, you'll need electrical power to activate the guns.
Cheers,
Hansi
