Cant get the propeller to change

Unity Engine
1

I am working on a basic fight sim for a very early plane and flowing Chris DeLeon very good tutorial and I have it running with by own plane and terrain .

I now would like to change the propeller ( I know i spelt it wrong in the script ) from the static wooden object to the prop1blur object when i hit the Q key and back again for the O key .

the script below runs but the propeller doesn’t change , I linked the objects in the script in the inspector but they just stay the way they are active when I start the script .

No idea why .

I have view many tuts but clearly don’t get it , as none are exactly what i need .

thanks Ruck

using UnityEngine;
using System.Collections;

public class birdControllor : MonoBehaviour {
    public float speed;
    public float roll;
    public float lift;
    public GameObject propellar;
    public GameObject prop1blur;


    // Use this for initialization
    void Start () {
        speed = 0;
        roll = 30;
        lift = 30;
    }

    // Update is called once per frame
    void Update () {
                #region Horizontal Rotation
                if (Input.GetAxis ("Horizontal") < 0)
                        transform.Rotate (0, 0, roll * Time.deltaTime);
                else if (Input.GetAxis ("Horizontal") > 0)
                        transform.Rotate (0, 0, -roll * Time.deltaTime);
                #endregion

                #region Vertical (X) Axis Rotation
                if (Input.GetAxis ("Vertical") < 0)
                        transform.Rotate (lift * Time.deltaTime, 0, 0);
                else if (Input.GetAxis ("Vertical") > 0)
                        transform.Rotate (-lift * Time.deltaTime, 0, 0);
                #endregion

                transform.Translate (0, 0, speed * Time.deltaTime);

                //this is a hard wired connection to the "F5" Key on the keyboard, switch it any keyboard key if you like
                //this will disable the camera inside of the car, and enable the camera outside of the vehicle
                if (Input.GetKey (KeyCode.Q))

                        speed = speed + 2;
                        prop1blur.SetActive(true);
                        propellar.SetActive(false);


        //this is a hard wired connection to the "F6" Key on the keyboard, switch it any keyboard key if you like
        //this will disable the camera behind the car, and enable the camera inside of the vehicle
        if (Input.GetKey (KeyCode.E))

                        speed = speed - 2;

                if (Input.GetKey (KeyCode.O))

                                speed = 0;
                               prop1blur.SetActive(false);
                               propellar.SetActive(true);

This is probably wrong. Judging by the indentation.
You probably meant this:

if (Input.GetKey (KeyCode.Q)) {
    speed = speed + 2;
    prop1blur.SetActive(true);
    propellar.SetActive(false);
}

It is useful to use the if () {} always, even if you have one statement after the if and after the else. You don’t do this kind of mistakes.

ps: I will leave it to you to find the other instance where you did the same.
