RCPano supports the DJI Spark, the smallest drone built by DJI. Because of its minimum size it can be always with you, with TapFly, ActiveTrack and Gesture you can create stunning shots.
For the creation of professional panorama shots the Spark is only partially usable:
Because of its low weight of only 300g the Spark is prone to wind, much more than the Mavic or the Phantom. Expect at least some of your your shots to be unsuccessful with low altitude or even small wind.
Two axis gimbal
While the big brothers of the Spark can move their gimbal in any direction, the Spark is only able to move the gimbal in two directions. Every roll movement of the drone will have impact on the shot.
To create HDR shots (what you typically do when the sun is visible in your panorama) you have to take more shots of the same scene that are combined to one image with a high dynamic range. The more pictures are taken, the better the result will be. The Spark only supports three images in AEB mode with a fixed EV value of 0.7. The missing adjustment of roll movements by the gimbal makes it even harder to create HDR images, because they often significantly differ.
Using appropriate software you can darken overexposed or brighten up underexposed areas of a RAW image, which is possible only to a limited extend with JPEG. Unfortunately the Spark does not support RAW shots.
No gimbal tilt upwards
A nice effect of an interactive panorama is to be able to look up into the sky a bit. To support this, the camera has to be moved upwards. Mavic and Phantom can tilt the gimbal upwards up to 30 degrees, the Spark isn't capable of moving the gimbal upwards.
The Spark is small, easy to handle and you always have it with you. But for creating professional panoramas you should use the bigger models.
