my blue ray 450 pushes aginast the ground and doesnt go up.. Why not? It worked at first... Now it doesnt.. its like its trying to go down and not up.

Are the toggle switch's on the radio both switched forward?The one on the left is idle up and will give you negative pitch for flying inverted when throttle stick is at bottom.

I forgot to mention which way the switch should be,for normal flight the toggle should be flipped forward,and flipped back towards you will be idle up.Hope this helps.

It should be flipped backwards away from you, that's normal mode.
