Let's Talk Gimbals

The recent problems I have been having with choppy or jerky videos, have prompted me to consider gimbal operation and the function of the gimbal. I'm very new to all this, so please put up with a really basic question:

I think I have figured out the difference between a 2-axis and a 3-axis gimbal. What I am not sure about is the physical relationship between the gimbal and the camera. Let's say I wanted to change a 2-axis gimbal to a 3-axis gimbal on my Phantom 4. Can I pick up ONLY the gimbal, remove my present gimbal and replace it with the new gimbal, still using the same camera? Or would I have to purchase both a new (3-axis) gimbal and a new camera to go with it?

I suspect they are independent, and I could use my present camera on a new gimbal, but I'm not sure. So that's my question.
 
Ren is correct: you do have a 3-axis gimbal. What you don't have is manual control of pan.

Hold the quad in your hand (with it turned on) and turn it through the yaw axis. You will see that the gimbal moves slower than the quad. The yaw speed is adjustable in the gimbal settings. The 3rd axis is controlled by the quad to smooth out rapid yaw movement for better cinematic effect.

OK - I'm listening. So let's suppose my quad is hovering at 100 feet. I want the camera to begin a slow, 360-degree shot, panning all around the point where the quad is hovering in a stationary position. How do I do that while keeping the quad not only hovering in the same spot, but also pointing straight ahead at all times? In other words, how do I move the camera horizontally without moving the quad itself? Because I haven't been able to figure that one out yet.

You can't. You need to yaw the quad to film that shot. And think about it: if you COULD do it, you would be looking at the quad's landing gear a lot in your video.

OK, I get that. But take a look at my reply post to Renov8r, above. In your example, the gimbal is panning, but only because the quad itself is also panning. If I have a 3-axis gimbal, shouldn't I be able to pan the camera (move it horizontally) while the quad itself remains still?

Not with DJI gimbals. I can with my Tarot gimbals though:cool: Thing is though, that's on a frame with retractable landing gear

And yet I have a 3-axis gimbal? How is that? Let me put it another way. I want to be able to control horizontal movement of the gimbal with the quad standing still. How can I get that done?

Yours is moving in 3 axes. You just can't control its movement manually in the yaw axis.
 
One question I have, How do you control the gimbol's movement while operating the quad from the controller? It would seem impossible unless you have a third control on the controller just for the gimbol.

Yep, on the DJIs there's a dial on the controller you use to control movement of the gimbal.
