How to choose the Quadcopter

I wanted to make this post as good as I can.

So, how to choose a quadcopter before you make the purchase decision?

What are the main features you may consider?

Total size

Maximum speed and altitude

Motors and propellers power

Maximum Payload

Quadcopter Maneuvers

Maximum endurance and flight time

Stills and Video Photography

Camera and its resolution and stabilization through gimbals

Communication and Navigation Peripherals like GPS, GSM, GPRS and 3G

Headless Mode

Safety Maneuvers like Back Home when loos of communication or before battery drainage


There are some kits if you consider building it yourself.

I saw a video showing some quadcopter with new features and technologies. Here they are: Phenox

This one is small and can be controlled using sounds like whistle.

CyPhy

This one comes with the GeoFence feature that predetermines the flight area which makes it suitable for training.

Carbone

The Carbon Fiber Paper Airplane

This one looks exactly as the paper plane design we are used to but with a fuselage made of reinforced carbon fiber and can be controlled with a smart phone.

Hexo

PlexiDrone

DJI Mavic Pro

3DR Solo
