Waypoint system index out of range?

Hey guys bring to make a simple waypoint system so my spaceship dose loop the loops and u-turns, buy
following game objects in GameObject and then goes to the next game object in the group, but I’m getting Index is out of range…

using UnityEngine;
using System.Collections;

public class Manovers : MonoBehaviour {


	public GameObject LoopTheLoop;
	public GameObject uTurn;

	public GameObject[] LoopPoints;
	public GameObject[] TurnPoints;

	public GameObject Target;

	public PlayerControllerWizards Controlls;

	public int CurrentTarget = 0;
	public int MaximumTargets;
	public float dist;
	public int Manoover;
	public float turnspeed = 20f;

	public bool InManoover = false;

	// Use this for initialization
	void Start () {
		Controlls = this.gameObject.GetComponent<PlayerControllerWizards> ();
	}
	
	// Update is called once per frame
	void Update () {
	
		if (Input.GetButton ("ManoverOne") && InManoover == false) {
			InManoover = true;
			GameObject Clone;
			Clone = Instantiate (LoopTheLoop, this.transform.position, transform.rotation) as GameObject;
			Manoover = 1;
		}

		if (Input.GetButton ("ManoverTwo") && InManoover == false) {
			InManoover = true;
			GameObject Clone;
			Clone = Instantiate (uTurn, this.transform.position, transform.rotation) as GameObject;
			Controlls.enabled = false; // Disable controlls while in manoover;
			Manoover = 2;
		}

		// perform Loop the Loop
		if (Manoover == 1) {
			MaximumTargets = LoopPoints.Length;
			Target = (LoopPoints[CurrentTarget]);
			this.transform.rotation = Quaternion.Slerp (this.transform.rotation, Quaternion.LookRotation (Target.transform.position - transform.position), Time.deltaTime * turnspeed);
			if(Target != null && dist < 2){
				Target = (LoopPoints[CurrentTarget +=1 ]);
			}
			if (CurrentTarget > MaximumTargets) {
				Controlls.enabled = true;
				Manoover = 0;
				InManoover = false;
				Destroy(LoopTheLoop);
			}


		}

		// perform Utruns
		if (Manoover == 2) {
			MaximumTargets = TurnPoints.Length;
			Target = (TurnPoints[CurrentTarget]);
			this.transform.rotation = Quaternion.Slerp (this.transform.rotation, Quaternion.LookRotation (Target.transform.position - transform.position), Time.deltaTime * turnspeed);
			if(Target != null && dist < 2){
				Target = (TurnPoints[CurrentTarget +=1 ]);
			}
			if (CurrentTarget > MaximumTargets) {
				Controlls.enabled = true;
				Manoover = 0;
				InManoover = false;
				Destroy(uTurn);
			}



		}

Before trying to access the array using the CurrentTarget as index value, you should check if it is greater than the maximum index value possible for that array. Like:

// Since MaximumTargets is the length of the array our index should be less than this value.
if(CurrentTarget < MaximumTargets) {
    Target = (LoopPoints[CurrentTarget]);
}

Also when you are incrementing the CurrentTarget value and using it.

if(Target != null && dist < 2){
     int nextTarget = CurrentTarget + 1;

    if(nextTarget < MaximumTargets) {
        Target = (LoopPoints[nextTarget]);
    }
}

And you should also check your index value for less than 0 conditions too.
