If the camera is mounted in a helicopter, why would a servo be needed to pan the camera? Just turn
the helicopter.

Here's one thing that I've learned from my 24 hour crash course:
People say that flying the helicopter at the same time that you're
taking pictures is difficult (easily believable). What they
recommend instead is putting the 'copter into automatic hover mode so
that it holds position by itself. Then you are free to focus on the
photography (no pun intended) as long as you can pan and zoom the
camera. As you well know, I am definitely not an expert but it does
sound reasonable.
