Why does my player fly up the Y axis?

So, I just started making this little game in unity. I made the player that consists of a cylynder as a body and a sphere as a head and a camera. The only scripts added to the player are FPSInputController, CharacterMotor and MouseLook scripts. The problem is that every time I press the play button to test the game, the player randomly falls, more like flies upwards the Y axis. Any answers?

Thanks in advance.

Try turning off the colliders on your cylinder and sphere. If you have one as a parent and one a child, turn off the child first and then try running your game.
