How many blades is too many?

Most drones out there seem to be of the quadcopter variety, but what about hexa and octo copters? Do the extra blades help with stability? I’m planning on building a drone for photography and was wondering if going down the 6 or 8 prop route is worth it. Would it be a lot more complex than building a quad?Thank you! via /r/drones https://ift.tt/2pkUUFa
