problem while configurating controller

i am using mouse look script to look around in my game. and i am trying to config the Thunder master joy stick , i want to use throttle to look around , it works but when i start scene it automatically starts to rotate to left side.

and keeps rotating.

i don't know what is wrong with the code that it keeps rotating ??

 using UnityEngine;
 using System.Collections;
 
 [AddComponentMenu("Camera-Control/Mouse Look")]
 public class MouseLook : MonoBehaviour {
     
     public enum RotationAxes { MouseXAndY = 0, MouseX = 1, MouseY = 2 }
     public RotationAxes axes = RotationAxes.MouseXAndY;
     public float mousesensitivityX = 15F;
     public float mousesensitivityY = 15F;
     
     public float joysensitivityX = 3F;
     public float joysensitivityY = 3F;
     
     public float minimumX = -360F;
     public float maximumX = 360F;
     
     public float minimumY = -60F;
     public float maximumY = 60F;
     
     float rotationY = 0F;
 
     void Update ()
     {    
 
         float Xon = Mathf.Abs (Input.GetAxis ("Joy X"));
         float Yon = Mathf.Abs (Input.GetAxis ("Joy Y"));
 
         if (axes == RotationAxes.MouseXAndY)
         {
             float rotationX = transform.localEulerAngles.y + Input.GetAxis("Joy X") * mousesensitivityX;
             
             rotationY += Input.GetAxis("Joy Y") * mousesensitivityY;
             rotationY = Mathf.Clamp (rotationY, minimumY, maximumY);
             
             transform.localEulerAngles = new Vector3(-rotationY, rotationX, 0);
         }
         else if (axes == RotationAxes.MouseX)
         {
             if (Xon>.05){
                 transform.Rotate(0, Input.GetAxis("Joy X") * joysensitivityX,0);
             }
             transform.Rotate(0, Input.GetAxis("Mouse X") * mousesensitivityX, 0);
         }
         else
         {
             if (Yon>.05){
                 rotationY += Input.GetAxis("Joy Y") * joysensitivityY;
             }
             rotationY += Input.GetAxis("Mouse Y") * mousesensitivityY;
             rotationY = Mathf.Clamp (rotationY, minimumY, maximumY);
             transform.localEulerAngles = new Vector3(-rotationY, transform.localEulerAngles.y, 0);
             
         }
     }
     
     void Start ()
     {
         // Make the rigid body not change rotation
         if (rigidbody)
             rigidbody.freezeRotation = true;
     }
 }

i have set the input settings in input manager according to code.

if any one know the solution then please let me know how to solve this Thanks, in advance
