Flight Control UI

Hey! I have been trying to make a Flight Control code, where i want to control the flight with 2 Control freak joy sticks on adjacent sides, In which i want to control my flight link the gameAERo! ( https://itunes.apple.com/gb/app/aero!/id423650051?mt=8) i already have a flight control code with horizontal & vertical axis, what i want is,,,,,On Input of 2 horizontal axis should results in vertical.

Flight control Code which i have:

  var Obj : Rigidbody;
 var zrotForce : int = 1;
 var MaxRot : int = 90;
 var MinRot : int = -90;
 var rotupForce : int = 1;
 var speed : float;
 var speedincrease : float;
 var speeddecrease : float;
 var Maxspeed : int;
 var Minspeed : int;
 var takeoffspeed : int;
 var lift : int;
 var minlift : int;
 var hit = false;

function Start () {

 InvokeRepeating("Speed", .1, .1);

}

function Speed(){

if (CFInput.GetKey(KeyCode.Space)){ Mathf.Repeat(1,Time.time); speed=speed+speedincrease; } if (CFInput.GetKey(KeyCode.LeftAlt)){ Mathf.Repeat(1,Time.time); speed=speed-speeddecrease; } }

function Update () { var spd = Obj.velocity.magnitude; Obj.rigidbody.AddRelativeForce(0,0,-speed); var H=(CFInput.GetAxis ("Horizontal"))zrotForce; if (H){ Obj.rigidbody.AddRelativeTorque(0, 0, H(spd/100)); } var V=(CFInput.GetAxis ("Vertical"))rotupForce; if (V){ Obj.rigidbody.AddRelativeTorque(V(spd/100), 0, 0); }

 if(Maxspeed<=speed){
 speed=Maxspeed;
 }else{
 speed=speed;
 }
 if(Minspeed>=speed){
 speed=Minspeed;
 }else{
 speed=speed;
 }
     if (speed<takeoffspeed){
 Obj.rigidbody.AddForce(0,minlift,0);

 }
 if(speed>takeoffspeed){
 Obj.rigidbody.AddForce(0,lift,0);
 }
 if (Obj.rigidbody.rotation.z>MaxRot){
 Obj.rigidbody.rotation.z=MaxRot;
 }
 if (Obj.rigidbody.rotation.z<MinRot){
 Obj.rigidbody.rotation.z=MinRot;
 }

}
