The x,y,z are relativ to the center of the screen and have nothing to do with the camera's rotation or position.
So y = 1000; might be out of your screen borders.
Try x=100; y=0; z=0; and play test with theses values
Remember:
x: distance from the camera (depth)
y: right, left (negativ: right, positiv: left)
z: up, down

edit:
If you want to be able to see it from the beginning you need to set:
flags2 = SHOW;
