Requirements to know:
Camera mounts (multiple?, gimbal?)
Batteries (how many batteries do we need/want? - do we want to fly for the full 30min?)
Grabber attachment - base should probably be at least 20cm diameter
What do we need to carry (sizes and weight of all electronics)

Motor calculator: https://www.ecalc.ch/xcoptercalc.php
Number of rotors - http://www.dronefromchina.com/new/how-to-choose-the-UAV-from-4-rotor-6-rotor-8-rotor.html
4 rotors:
Cheapest/lightest
Can be smaller - min size around 362mm/14.25” frame size if using 10” props
If one rotor breaks then you will most likely crash
6 (and similar for 8):
Can carry more weight
Larger - min size around 525mm/20.5” frame size if using 10” props
More redundant so should survive if 1 rotor break
