RCS Question

I posted a question earlier about RCS issues and haven't seen a response, so here goes again. I really enjoy this sim and have a blast building rockets and flying them. The RCS is driving me up a wall. As I stated in an earlier post, RCS doesn't seem to respond at all when I use the command chip. RCS IS activated in the command chip menu. Pressing "T" in flight doesn't make any difference- still attitude control through RCS doesn't work- spacecraft is in free drift. With the command pod, pressing "T' gives some attitude control but still not like in the docking tutorial. The spacecraft in the docking tutorial exhibits realistic attitude control. I hear a hiss and see vapor coming from the RCS jets. In normal flight with a spacecraft I have made, I don't get the realistic attitude control nor do I get the sound effect and the vapor coming out of the nozzle.
Is there a proper way to attach the RCS nozzles to the spacecraft to get the realistic attitude control and sound & visual effects when the RCS engages?
