I did not try vertical shots yet. Though Spark cannot direct camera
completely vertically down as Phantom can. It has got the gimbal pitch
from -85 to 0 (-85 degrees is almost vertically down), and Phantom 3 & 4
has got from -90 to +30.
But the advantage is that it weighs only 300 grams, very portable, and
it is ready to fly almost instantly as folding propellers are fixed
permanently, and smart-phone connects to the remote control via WiFi, no
cables are necessary.
Best regards,
Oleksiy
