For aircraft that has separate lift engines, you can avoid and at the same time still use the trust vector control.
What I mean is you could set up the lift engines as regular engines (without trust vector control), but with an agnled thrust, by using this entry:
ThrustAngles=0.0,80.0,0.0 - this is an example setting of thrust 80 degrees downwards
Then you couls set up the lift engines to be without afterburner.
Finally you could use a different input for the throttle of the lift engines, for example:
InputName=THRUST_VECTOR_CONTROL
This way you will have main engine(s), using the throttle control with full afterbuner and you will have lift engines, using the trust vector control for throttle, without afterburner, i.e. 2 independent input settings for throttle of the diffent engines.
Then it is interesting to test if the thrust vector control can be used both as throttle control and as animation control to open and close the intake doors and exhaust covers of the lift engines.
If that does not work, may be the intake doors and exhaust covers can be controlled by means of a separate manual animation SHIFT+1 or 2 or else.
