How to usu it?
In cockpit view, on your left, there are two rows of switches, marked "APU" and "Engine". All open, followed by the two red buttons on your left, all open, and you will hear some sound, which means that the plane started successfully.
Cruise system:
The switch on your left, first from front to rear, is the cruise switch.
You need to use VTOL to control the cruise control system.
Sub-update:
The launch method has been changed, which is more flexible than the old launch method (vertical launch system). This time, more new weapons have been expanded, and some old weapons have been eliminated.
Change in appearance
Of course, for unstable RCS systems, I wrote a flight control program specifically for them, which makes the system more reliable and does not need to correct errors manually.

Have a good time!
