flipping a material

[Master chief]

OK quick question. i am trying to use the streak emitter to place an effect like a rocket taking off . but for some reason the streaks jump up then fall down instead of just blasting down. i know this should be simple but i cant get it to blast the other way

in the model window, flip the normals on those patches
