Although this is technically not required, you should always have a manual backup for your drone in case something goes wrong.   Your RC radio gear is also used when you are learning how to fly, or when you want to fly in manual modes.  If you want to find out some more click the button below

You will obviously need a platform to build your multi rotor UAV.  The frame is the actual UAV.  There is a huge range of choices of frames.  The most common configuration is a quadcoper with 4 motors.  However if you want to carry a lfancy camera, or a heavy load then more motors are needed.  Hexacopter (6 motors), and Octacopter (8 motors) are ideal for heavier loads.  For more information on frames then click the button below.

As you can imagine, the motors, Propellers are a fairly important aspect of your multi rotor since they will provide the lift for your UAV to fly around.  Multi Rotor motors tend to have a lower Kv rating than fixed wing motors, this is because they are designed to spin slower, but produce more torque.  This allows you to use larger propellers for maximum efficiency and flight time.  For more information on Motors, Propellers and Speed Controllers click the button below

The flight controller is the brains of your Multi rotor UAV.  Flight controllers are used to help stabilise your multi rotor, and some more advanced flight controllers can also autonomouly fly your UAV to pre programmed waypoints including takeoff and landing.  The choise of autopilot/ flight controller is mainly dependant on what you want and your budget.  For more information click the button below.

The battery provides power to your UAV.  The battery will control both your Flight Controller and Motors.  Lithium Polymer batteries are almost always used for multi-copters as they have a high power to weight ratio and are readily available.When choosing a battery the two main factors are the capacity, and voltage.  The voltage is dependant on the number of cells (3 or 4 cell are common).  The capacity common ideal for multi-rotors are around 3000mah.  The higher capacity generally enable longer flight times, but since they are heavier there is a limit depending on what other payload you want to carry such as cameras.
