But what if quadrotor drones aren’t even the best way to make drones? What then? 

Ascent AeroSystems has rethought the drone form with their Helius model. 

It consists of a vertically-oriented body and just two rotors, one stacked over the other, in a coaxial arrangement.

Stacking the two rotors generates more thrust per unit area while keeping the form compact; there are no bulky arms that need to extend outwards. This arrangement, the company says, makes the drones more compact and easy to store; allows them to carry heavier payloads; offers better reliability and, with its narrow profile, stands up better to harsh weather.

some thoughts
- honestly this whole "rethought the drone thing" is complete BS
- this is a known form factor 
- as with vehicle / dynamics / control design -- its all design trade offs - what is your mission and what are you maximizing for?

sure you get:
- benefits of with coaxial rotors, you have a shorter moment arm for pitch, roll, yaw
- better thrust to weight per area
- but that means you need a weirder more precise (is my guess) control strategy
- multirotor drones have well known control strategies
- control-tuning standpoint means you gotta do your own thing which is cool but just less proven, means more testing
- lack of redundancy - if you have more rotors, it means better redundancy. with 2 coaxial rotors, you lost one rotor you lost 50% thrust - not the best

again - it's all A) what is your mission B) what tradeoffs are you making C) there is no single bullet that solves all missions

pretty crazy that conservatives are scared of the media turning kids gay instead of worrying about these aerial attack butt plugs
