The Solo gets its name because you can do what has traditionally required two operators, by yourself, i.e.. "solo"
You will have the option to set up a smart shot and just let the Solo do everything, or you can control the gimbal tilt and the speed of smart shot with your controller while the Solo handles the bulk of the flying.
So for example, lets say you want to do an Orbit of a church tower. The simple thing would be to set up an Orbit smart shot, hit play and stand back doing nothing. Or if you want to be a little more involved, you could set up the Orbit smart shot, hit play, and then pull the right stick back while it circles the tower, thereby increasing the distance from the church (push forward to reduce the radius). From above this would look like a spiral, but the Solo will keep the church tower in the center of the frame the whole time.
Or, you could do all the above, but also move the left stick up and down to change altitude while the Solo circles the tower.
Or, you could set up the smart shot, DO NOT hit Play, but instead move the right sticks side to side to move the Solo along the Orbit at whatever speed you want. Simultaneously you could be using the left sticks to change altitude. So you get a kind of spiral cork screw shot, but the Solo will make sure the camera stays pointed at the church tower.
Its also important to note that when you do these kinds of orbits, you can also set an altitude for the target, in this case a church tower. You probably don't want the camera aimed at the base of the church, but rather the top of the tower. So you set a height, and even if you are using the left sticks to change altitude while the smart shot plays, the gimbal will tilt the camera up and down to keep the top of the tower in the center of the frame. Of course, while this is going on, you can over-ride the tilt using the controller.
That was a long post. Hope it helps.
(FYI, you can use the Tower app on Android to do even more complex shots).
