Where to buy quadcopter parts

Introduction
With each passing day, Quadcopters becomes more popular and in high demand. This is largely due to their appeal to a wide array of hobbyists including amateur filmmakers, photographers and nature lovers among many others. As a hobbyist, having a basic understanding of the different parts of a quadcopter can help in troubleshooting repairs and can help when you’re trying to modify a quadcopter to suit your specific needs.
A quadcopter looks like a complex piece of machinery and it may seem like an intimidating prospect to modify or fix such a thing at home. But the truth is that if you have an understanding of the parts, it becomes much easier. Quadcopter components are designed to come together pretty easily, and if directions are followed, you can actually build a DIY quadcopter at home! Let’s take a look at the parts that will be needed to accomplish this awesome feet and where to purchase them.

What are the various parts of a Quadcopter?

Chassis
Frame or chassis is the skeleton of a quadcopter. There are a few motors and propellers that are connected to it. Quadcopter chassis come in a variety of sizes and weights. Most of the frames have the similar X shape. If you intend to augment additional components such as a camera to the frame, you will be required to get your hands on a chassis with higher weight ratings. However, if the frame consists of a rugged material, it will itself add more weight to the quadcopter; thereby requiring you to opt for longer propellers and heavier motors to provide the necessary thrust needed to lift the quadcopter from the ground. Quadcopter engineers endeavor to keep a balance among flight speed, handling and flight duration by using appropriate quadcopter parts.

Motor
The next and probably most important component is the motor. Motors are rated in “Kv” units, which equate to the number of revolutions per minute a motor can achieve when a 1v current is introduced to it unhindered. The higher the Kv, the faster the motor can spin. However, faster is not always better. A faster motor spin requires much more power from the battery, causing your flight times to decrease. More RPMs also decrease the life of the motor over the long run.

Propellers
Regarded as one of the most important quadcopter parts, propellers influence the speed at which a quadcopter can fly, the payload it can carry and the speed at which it can be handled. So, by varying the length and pitch or a propeller, you can toy with the above mentioned variables. The pitch is essentially the shape and slant of a propeller.

Electronic Speed Controller (ESC)
An ESC supplies the proper modulated current to the motors, which in turn produce correct rates of spin for both lift and maneuvering. There are fewer things to consider with an ESC than with other components since they’re a fairly standard part, but there are two small factors. Most ESCs come with the SimonK firmware, which is designed for the precision timing of multiple rotors which a quadcopter uses. This is a standard feature in most ESC designs now. Usually ESCs also come with a battery eliminator circuit (or BAC), which allows the flight control and transceiver components to connect to the ESC rather than directly to the battery.

Flight controller
Flight controller is the basic brain behind the quadcopter. It is a small sized computer that controls the aircraft and translates the signals received from the transceiver to guide the device. If you like to build your own quadcopter, choosing a flight controller boils down to your personal choice. There are number of flight controllers out there with different features and customization options.

Radio Receiver
So how does the flight controller receive signals from the transmitter (the remote control)? That’s the radio receiver’s job. This consists of a component which connects to the flight controller, to receive signals, and a controller to transmit them. There are a lot of very slick receivers which work quite well with standard quadcopter flight controllers. However the key is to be sure that it supports at least four channels if not as high as eight or nine.

Battery and Battery charger
Here is another important one of the quadcopter parts. A LiPo (Lithium Polymer) battery typically acts as a power source for the quadcopter. LiPo batteries use a C rating that is actually the capacity of a battery to get discharged. Generally, you will come across LiPo batteries with 20C rating. So, if you come across a 25C 4000mAh LiPo battery, it means that you get a maximum of 25 x 4 = 100 Amps. The power of a battery is typically rated by the energy draw required of an ESC. For instance, if your motor draws a maximum energy of 19A, you will need an ESC with at least 30A. Multiplying this by the number of propellers and you get the maximum current drawn from your quadcopter which is 76A.
