Adding spin to propeller

I have added spin the crashed planes broken propeller as an extra feature of the starting area.

Below is the simple C# code I used to add the spin to the propeller:


using UnityEngine;
using System.Collections;

public class Propellerspin : MonoBehaviour {

// Use this for initialization
void Start () {

}

// Update is called once per frame
void Update () {
transform.Rotate(Vector3.up * 3);
}
}
