Why do the CSAT helo keep crashing

[BEAKSBY 11]

...yet this works for the NATO side?

I've created a script that spawns Helos based on your side.

But if you're CSAT the, only one Helo is spawned then crashes into the ground?

//Side related group creation:
switch(side player)do{
case WEST:{
	_center = createCenter west;
	_grp = createGroup west;
	_planeType = "B_Heli_Light_01_armed_F";
};
case EAST:{
	_center = createCenter east;
	_grp = createGroup east;
	_planeType = "O_Heli_Light_02_F" ;

};
};

// SPAWN PLANES
for "_i" from   0 to 2  do {
sleep .05;
_spos = [(getPosATL player select 0) - (sin _planeDirection) * _planeDistance, (getPosATL player select 1) - (cos _planeDirection) * _planeDistance , 50];	
if (_i == 1) then {
	_plane1Pos = [_spos, _planeSpread,_planeDirection -90] call bis_fnc_relpos;
	_plane1Pos set [2,_flyHeight];
	_spos = _plane1Pos;
};
if (_i == 2) then {
	_plane1Pos = [_spos, _planeSpread,_planeDirection +90] call bis_fnc_relpos;
	_plane1Pos set [2,_flyHeight];
	_spos = _plane1Pos;	
};	
_plane = createVehicle [_planeType, _spos, [], 0, "FLY"];
_plane setRank "LIEUTENANT";
if (_i == 1) then {
	_plane setRank "SERGEANT";
};
if (_i == 2) then {
	_plane setRank "SERGEANT";
};	
//_grp setSpeedMode "FULL"; 
_plane setDir _planeDirection;
_plane flyInHeight _flyHeight;	
// PRESET VELOCITY
/*
_vel = velocity _plane;
_plane setVelocity [
	(_vel select 0) + (sin _planeDirection * _speed), 
	(_vel select 1) + (cos _planeDirection * _speed), 
	(_vel select 2)
];
*/
(side player == WEST) then {_plane setAmmo ["missiles_DAR", 0]} else {_plane setAmmo ["missiles_DAGR", 0]};
_plane allowDamage _allowDamage;
_plane setSkill 1; 

// MAY HAVE TO REMOVE CREW FIRST
_crew = crew _plane;
{deletevehicle _x} foreach _crew;
_crew = [_plane,_grp] call bis_fnc_spawncrew;
_grp setFormation "VEE"; 
_planeArray = _planeArray + [_plane]; 
_plane sideChat "Air Cav on it's way!";
};

Not sure what your problem is at first-glance, but I did change a bit of code and add a lot of comments with suggestions/changes.

_opCenter = createCenter west; //move to init.sqf
west setFriend [east, 0]; //move to init.sqf
_bluCenter = createCenter east; //move to init.sqf
east setFriend [west, 0]; //move to init.sqf
//Not sure if the above code is actually necessary at all, I have spawned opfor units with scripts in empty missions before without having problems. Either way, you only want this code to run once, because each side only needs one Center.

_planePilots = []; //for testing purposes

switch(side player)do
{
   case WEST:{
       _planeType = "B_Heli_Light_01_armed_F";
   };
   case EAST:{
       _planeType = "O_Heli_Light_02_F" ;

   };
};
_grp = createGroup (side player);

for "_i" from   0 to 2  do {
sleep .05;
_spos = [(getPosATL player select 0) - (sin _planeDirection) * _planeDistance, (getPosATL player select 1) - (cos _planeDirection) * _planeDistance , 50];    
if (_i == 1) then {
	_plane1Pos = [_spos, _planeSpread,_planeDirection -90] call bis_fnc_relpos;
	_plane1Pos set [2,_flyHeight];
	_spos = _plane1Pos;
};
if (_i == 2) then {
	_plane1Pos = [_spos, _planeSpread,_planeDirection +90] call bis_fnc_relpos;
	_plane1Pos set [2,_flyHeight];
	_spos = _plane1Pos;    
};    
_plane = createVehicle [_planeType, _spos, [], 0, "FLY"];

if (_i == 0) then
{
	_plane setRank "LIEUTENANT";
}else
{
	_plane setRank "SERGEANT";
};

   /*
   if (_i == 1) then {
       _plane setRank "SERGEANT";
   };
   if (_i == 2) then {
       _plane setRank "SERGEANT";
   };
   */ //can be done with one "if" statement

   //_grp setSpeedMode "FULL"; 
   _plane setDir _planeDirection;
   _plane flyInHeight _flyHeight;    
   // PRESET VELOCITY
/*
   _vel = velocity _plane;
   _plane setVelocity [
       (_vel select 0) + (sin _planeDirection * _speed), 
       (_vel select 1) + (cos _planeDirection * _speed), 
       (_vel select 2)
   ];
*/
if (side player == WEST) then //forgot to put "if" at the beginning.
{
	_plane setAmmo ["missiles_DAR", 0]
} else
{
	_plane setAmmo ["missiles_DAGR", 0]
};
_plane allowDamage _allowDamage; //_allowDamage not defined in posted code
_plane setSkill 1; //maximum skill?

   // MAY HAVE TO REMOVE CREW FIRST
   {deletevehicle _x} foreach (crew _plane); //no need to assign a new variable
   _crew = [_plane,_grp] call bis_fnc_spawncrew;
   _grp setFormation "VEE"; 
   _planeArray = _planeArray + [_plane]; //_planeArray will only be available in the current script. Also, not necessary to do this when you can use (units _grp) to get an array with all units in the group.
   _plane sideChat "Air Cav on it's way!"; //message will be sent 3 times
   _planePilots pushBack (driver _plane); //puts each pilot into an array
};

[] spawn //will display all helicopter pilots. Used for testing.
{
while {true} do
{
	hintSilent format["%1", _planePilots];
};
};

Also, I'm not sure what you mean by it spawns and then crashes into the ground. Does it tilt downward and to the right? This is a sign that there's no pilot (I added code already to easily check that).

Thanks DreadedEntity,

I missed a lot of code efficiencies you pointed out.

I'm trying to keep my helos all in formation but it's not working with setFormation.
