I'm assuming you're talking about two player split screen here? If it is then you can use an approach like so ....
Set up a GUI camera with a very low range, position it far enough away from everything so that your planes will never be near it. Set the cameraclsmode so that the previous camera renders are preserved and set the entityorder on the GUIcamera to be drawn last.
Parent your dials to this camera ( you will need to play about with their offset to ensure they fit on screen properly ). During renderworld() you then shouldn't have to hide anything.
