kOS script for a shuttle

[samsunix]

Hello and sorry if I post this in wrong place.

I'am working with kOS script to get my shuttle to orbit but I have couple of problems.

First problem is with a stage to separate boosters when they flame out / are empty.

Second Problem is at stage when I should turn off main engine. Here is what I got so far:

CLEARSCREEN.
PRINT "Counting down:".
FROM {local countdown is 10.} UNTIL countdown = 0 STEP {SET countdown to countdown - 1.} DO {
    PRINT "..." + countdown.
    WAIT 1.
    CLEARSCREEN.
}
LOCK THROTTLE TO 0.5.
STAGE.
WAIT 1.
STAGE.
PRINT "LIFT OFF!".
lock steering to lookdirup(heading(90,85):vector, ship:facing:topvector).
WAIT UNTIL SHIP:ALTITUDE > 3000.
PRINT "Adjusting to 80 degree".
lock steering to lookdirup(heading(90,80):vector, ship:facing:topvector).
WAIT UNTIL SHIP:ALTITUDE > 4000.
PRINT "Adjusting to 75 degree".
lock steering to lookdirup(heading(90,75):vector, ship:facing:topvector).
WAIT UNTIL SHIP:ALTITUDE > 5000.
PRINT "Adjusting to 70 degree".
lock steering to lookdirup(heading(90,70):vector, ship:facing:topvector).
WAIT UNTIL SHIP:ALTITUDE > 6000.
PRINT "Adjusting to 65 degree".
lock steering to lookdirup(heading(90,65):vector, ship:facing:topvector).
WAIT 3.
PRINT "Waiting boosters flameout...".

// I have tryed: 

// WHEN STAGE:SOLIDFUEL < 10 THEN {
 // WAIT 2.
 // STAGE.
 // }.

// and another one:

//LIST ENGINES IN elist.

//set seperation to false.

//UNTIL(//don't know what I should but here){
//    if(seperation){
//        LIST ENGINES IN elist.
//        set seperation to false.
//    }
//    FOR e IN elist {
//        if (e:FLAMEOUT and STAGE:READY){
//            STAGE.
//            set seperation to true.
//        }
//    }
//}.
RCS ON.
WHEN SHIP:APOAPSIS > 75000 THEN {
LOCK THROTTLE TO 0.0.
}.
lock steering to prograde.

// something to turn off main engines

WAIT 5.
STAGE.
WHEN SHIP:ALTITUDE > 75000 THEN {
LOCK THROTTLE TO 0.9.
}.
WHEN SHIP:periapsis > 75000 THEN {
LOCK THROTTLE TO 0.0.
}.

Thank you for your help

If you do:

 

// FLAMEOUT CHECK:

LOCAL FLAMEOUT IS FALSE.
LIST ENGINES IN ENGLIST.
FOR ENG IN ENGLIST {
  IF ENG:FLAMEOUT {
    SET FLAMEOUT TO TRUE.
  }
}
// IF FLAMEOUT IS TRUE NOW, THEN AT LEAST ONE ENGINE HAS FLAMED OUT.

 

Then you can see when any engine has flamed out.
