object launching trouble (Timing)

i was to lazy tonight to make my own launching script so ive been editing this one, the trouble is the rocket is launching from a plane going 30+ mps when it launches it has a delay with the timer im trying to get rid of that delay. the rocket will spawn stay frozen for .1 seconds then launch by that time the plane normaly loses alt very slightly and the rocket nails you in the back end anyone have any isdea what i could do or any ways to fix my little issue

float gTotalTime = 0.0;
float gTimeStep = 0.1;

float FLIGHT_TIME = 6.0;
float THRUST = 15.0;

integer launched = FALSE;

launch()
{
    launched = TRUE;
    gTotalTime = 0.0;
    llSetStatus(STATUS_PHYSICS, TRUE);
    llSetForce(<0,0,THRUST>, TRUE);
    llSetTimerEvent(gTimeStep);
    llTriggerSound("launch", 1.0);
    llMakeExplosion(20, 1.0, 5, 3.0, 1.0, "smoke", ZERO_VECTOR);
}
default
{
    state_entry()
    {
        llSetBuoyancy(1.0);
        llPreloadSound("launch");
        llPreloadSound("explosion");
        llSetStatus(STATUS_PHYSICS, FALSE);         
    } 
    on_rez(integer param) 
    {
        if (param > 0)
        {
            llSetStatus(STATUS_PHYSICS,TRUE);
            llSetTimerEvent(.1);      //  Wait passed number seconds then launch
        }
    }    
    timer()
    {
        if (!launched)
        {
            launch();
            return;    
        }
        gTotalTime += gTimeStep;
        if (gTotalTime < FLIGHT_TIME)
        {
            llMakeExplosion(5, 1.0, 2, 3.0, PI, "smoke", ZERO_VECTOR);
        }
        else
        {
            llSetStatus(STATUS_PHYSICS, FALSE);
            llSetForce(<0,0,0>, TRUE);
            llTriggerSound("explosion", 10.0);
            llMakeExplosion(20, 1.0, 10, 3.0, 1.0, "green", ZERO_VECTOR);
            llMakeExplosion(20, 1.0, 10, 3.0, 1.0, "blue", ZERO_VECTOR);
            llDie();
        }        
    }
    collision_start(integer num)
    {
            llSetStatus(STATUS_PHYSICS, FALSE); 
            llSetForce(<0,0,0>, TRUE);
            llTriggerSound("explosion", 10.0);
            llMakeExplosion(20, 1.0, 5, 3.0, 1.0, "green", ZERO_VECTOR);
            llMakeExplosion(20, 1.0, 5, 3.0, 1.0, "blue", ZERO_VECTOR);
            llDie();
            
    }
}

Probably it is running out of energy. You can't keep more than a small object (about avatar sized) afloat for very long using normal physical movement. You'll have to switch to vehicle functions, which ignore mass. Or non-physical movement maybe, but I'd try the vehicle functions first.

Is llMakeExplosion still being used?

yep it is still being used, and i highly dought it is running out of energy, the problem lies in the llSetTimerEvent() area id light to make it launch the second it spawns couse even .1 second delay is enought to get yourself shot out of the sky with your own rocket

might also change the offset to be forward of the rezzor so it rezzes and stays in front, since you also have load time for the scripts in the rocket to be instanciated on the server
