Character Controller Flying up into the sky

Hi, I'm very new to Unity and I have a problem. I've made a map and made a player just by using some cubes and spheres for the head etc. I've imported the standard first person controller physics to my player object, but the charachter just flies up in the sky whenever i press play. He never comes down just slowly keeps on going into the sky. Any solutions? (It's supposed to be a snowboard game).

 

This may seem like a silly question, although I do not see one in your inspector image. Do you have a rigidbody attached to your player?
