I am starting to make a hovering vehicle. It acts more like a baloon than an airplane. It is slow and goes forwards and backwards. Now, the only difficulty I have is rotating the craft on its Z axis. I need to be able to set the heading so that I can get places that are not in front of or in back of my craft!

Any suggestions? Again, I want it to work like a baloon, so I do not want it to bank, just rotate along the Z axis. Like a hovering helicopter.
Thanks!
