fps change graphic

I want to have my own FPS model instead of the cyclinder .
To do this I tried

  1. look for a way to swap the cyclinder over to my image (say a cube for now).Couldnt find how to do this.

  2. deleted the fps and created a cube with a camera and tried to add a Thirdpersoncontroller.js
    to the c# project to control movement and this didnt work.

What method is used to change the fps model from a cyclinder to what I want.

You need to make your object a child of the player object in the fps controller, to be honest you should go do some tutorials before coming to answers with questions like this. Check out http://unity3d.com/support/resources/tutorials/ to get started using Unity.

Good luck
