Hello Nick!
I followed the instructions for operating the guns but they don't work.
What is the target CG value for this airplane?
The speed brake switch in the cockpit toes to the out position but not the in position. I can stow the speed brakes only with my controller.
1) Do you miss the gun sound or the visual effect (tracer bullets) or both? Are you using hardware pedals?
2) The speedbrake switch can be operated with the mouse-wheel, but only if you don't have a joystick axis assigned to the spoiler position. In that case, the joystick may "overrule" the speedbrake button if the hardware lever has been left in the OUT position. It should be placed in the deadzone if the speedbrakes are to be operated with the button on the throttle stick.
Cheers,
Hansi
