So you are interested in Quadcopters, Quadrotors, Uavs, Drones and whatever else they call them.
But what are they made up of, and why? Could i build one or are they for more advanced electronic type individuals.
Well never fear. I present to you a basic overview and build of a basic quadcopter in full.
(around $220 plus shipping not including transmitter,receiver or lipo battery charger)
If your more advanced and tech savvy you may choose to design your own setups but for the rest of you i would advise to stick to the components listed if possible to ensure all of it functions well. That said the frame and batteries can be different. I would advise the batteries be a similar size or you will get less flight time. I brush over a lot of the components to give a basic understanding of what they are for. If anything is unclear feel free to ask questions or even hit some forums or google it yourself as that is how i learned all of this.

I will not cover fpv, groundstations or autonomous drones in this as if can easily confuse people so i may do another instructable for them another time perhaps.  

Hopefully you enjoy my first instructable.
If i get a good response i may do another.



Step 1: Basic Quads Systems & My Easy Quad Build

BASIC QUAD SYSTEM COMPONENTS EXPLANATION.

I have created some basic explanations of the components and what they do. (I wish someone did this for me)
Page 4-10 Contains a list of materials and steps to build a great quality quad. (Strong and great fun for learning)
Cost around $220 Aud in materials

(not inc. Lipo Battery Charger, Transmitter, receiver + Your freight costs will be different)
(Obviously you only need to buy the Lipo Charger and Transmitter once.)


Drones and quadcopters can quickly become and obsession, but before investing in some serious equipment, learning to fly a quad is the key to minimizing costly crashes and damages. But they practically fly themselves right? Well, yes and no.
This is all dependent on the equipment you select for your build. That’s easy right, you just want the best, but it all can add up pretty quickly when planning out your system. But before you start spending you hard earned dollars on components LET IT BE KNOWN THAT RESEARCH IS VITAL. An understanding will help minimize the headaches of your build and identifying problems. Once that package of goodies arrives after 2 weeks of waiting you rush to the garage to assemble your beast only to realize you forgot something or ordered the wrong thing. You then will spend the next ten minutes swearing your head off and ordering the other stuff only to a wait another two weeks for it to come. Within this waiting time you will find better components you wish you had of ordered instead. This is the how it all goes. So it pays to buy extra components and spares just incase something isn’t what you thought. You can always upgrade later down the track.
Hopefully this will help you to nail it all first shot.

DESIGNING YOUR OWN

If designing your own setup you will have to put the time in finding out good combinations of motor, battery and prop size/pitch etc.
This is not unachievable but perhaps to start with may be difficult for some of you newbies. If you are designing your own quad from scratch you should know that it is not quite as simple as buying components and assembling them.
Many factors must be considered including motor size and weight as well as battery C/burst ratings and MaH’s of batteries and more. How much weight do you want to lift if any? Such as cameras and fpv gear etc (=payloads) All of these factors must be considered when designing.
A handy helpful tool I used to calculate my quad stats was the free online xcopter ecalc. It can be found here:

http://www.ecalc.ch/xcoptercalc.htm?ecalc⟨=en

BUT

If your using my setup i have done all the work for you! 



****WARNING Be responsible with your Quadcopter as 4 spinning props can chop your beautifully manicured fingers to shreds!!!!!
I also will not be held responsible for any damage inflicted to yourself and or others including property and equipment etc.

Please take precautions to effectively test your equipment and Pre check before each flight. This is your responsibility and safety is your priority.
If something seems dodgey it probly isn’t worth the risk.

Trust me I have had some close shaves literally!!!!!!!!!!!!
It can all go from wooooo to ahhhhhhhhh pretty quickly.
So keep a distance and take precautions to maintain your safety and the safety of others. Always assume something is going to go wrong so you are prepared!!!!!!


Now with all of this being said we can begin.
Many hobby shops exist but some can be quite expensive because obviously they need to make a living. These days online seems to be the best way to source your gear. That being said you may have better hobby shops than where I am so do your research and if your lucky it may work out cheaper and faster to source some if not all from your local hobby shop when you factor in freight etc.

The two main places I use to source my gear are:

Hobbyking (large company based in Hong Kong/Usa but ship worldwide)

Foxtech (similar but based solely in China with slightly less user friendly site still good though)

There are loads of others.

Dealing with both of these guys personally I am happy with there products but there are plenty of places you can get your gear from.
The Hobbyking item comments are a great place to learn about products before purchasing them they are listed below the actual products when you click on them. It will teach you a lot and other people will let you know if it’s crappy.
Also Rc forums are a great resource and there are plenty of them.
Youtube has plenty of videos also explaining a lot material if you are having problems. Look for solutions before asking questions.
Chances are someone has asked the same question before you.

I will be listing what I used for components as well as brushing over what they do to try provide information for people with different levels of understanding.
I will try to keep it as clear and brief as possible but it is a huge amount of info to attempt to consolidate.

This also is my first Instructable so if it helps please like/vote etc. 
I had to learn this all on my own over time because nothing like this was available.
So I hope this all helps. If i get lots of likes i may do another on fpv and building your own fpv groundstation.
<ol><br><li><p>i have prepared a drone but i have a small problem i&rsquo;m not able to get any signal to control board from reciever while reciever test. but i&rsquo;m getting signal from transmitter to reciever but not able to get signal from reciever to control board.can you help us in any way</p><p><a href="http://uavcoach.com/how-to-fly-a-quadcopter-guide/?replytocom=8301#respond" rel="nofollow">Reply</a></p></ol>
Hi<br><br>I would download the manual for your board if you don't already have it and check the signal flow. Also have you paired your remote with the receiver? You can download instructions on how to do this usually from where you bought your remote and receiver. Also there is an arming safety function which the manual should explain how to unlock. Also check the wires go to the correct pins on the input and output sides then check if the esc wires are around the right way. Check all your escs are connected to the battery and the other 3 small wires with a servo plug are connected the right way around to the board.<br>Also some escs have to be calibrated so if you haven't done that maybe try that as well. Hopefully if you try these things you can find the source of your problem. <br><br>Eben89<br>
<p>hey I am having problems with my quad lifting off. I built it to your exact specifications as I don't have much experience with RC. It just de isn't seem to provide enough downwards thrust. I have checked my battery and my motors and props but nothing is working. Would getting bigger or stronger props work? Help!</p>
Hi Rexc11 <br><br>Could be difficult to diagnose over the Internet but have you calculated the setup with ecalc? Also what size is your frame and what motors are you using? It sounds like perhaps it has weight issues. Definitly recheck your motor rotations and that you are using the right prop for that direction as listed in your flight control board manual/settings. Let me know how u go and hopefully we can find the problem.<br><br>Eben

Yes you can use any drone board you want. That's a newer version of the one in the tutorial. Good luck
<p>Sweet! Thanks for the feedback!</p>
What kind of tools should I get before I start buying my first set such as screw drivers and ect. ?
Tools will depend on what setup you get. Probably different types of hex/Allen keys (imperial and metric if possible as they can be be a pain) assorted screwdrivers and mini screwdrivers as some hardware for boards can be tiny. Also a soldering iron and solder if your setup isn't a full kit. Pliers also could be handy if you need to strip wires. Because a lot of these setups come from China sometimes you wont have what u need. But I always try to google instructions before I buy if possible to see screw types and what's included. If you are buying individual components always imagine they have no connectors and buy different sizes of extra connections in both sides/sexes so you have spares as otherwise you have to wait another 4 weeks if you are buying overseas.. Hope this helps. :) <br>
<p>wow great video...i learned a lot .... but hey i also found this app online that showed me a lot just by downloading it on my phone i started building my own drone here check this link out link https://play.google.com/store/apps/details?id=com.wDIY250QBuild</p>
<p>How much of a payload will this lift?</p>
Wow, this is great!
hello i have a few questions for you. could you please email me. stephen.bobzien@gmail.com
<p>those three cables that go to the reciever are pwm like you mentioned. connect the arduino ground to the ground of the lipo if it isnt already powering the arduino and the red positive to the power (possibly not the arduino positive as it may not have enough power) you will have to check it doesnt exceed the max arduino current draw. then the orange or somtimes white i think is the pwm which you will connect to your arduino pwm pin. Good luck</p>
<p>Hi I am trying to figure out the connections of the RC quad copter I am making. For controlling the motors, we are trying to use an arduino board that will fly along with the copter. So from the LIPO, connection will be made to the motor controller, from which three connections will go to the motor. But other than these, we also have three wires, which I am assuming is for the PWM. That is supposed to go to the receiver. Problem is, we are not planning to use the receiver but send that signal directly from the arduino. How can I make that connection? Please help.</p>

<p>Hi,</p><p>Very good instructable. I would like to know how is the approx total weight of the quad with a camera installed?</p><p>Thanks,</p>
<p>I have many questions, disagreements, suggestions, R/C racer for 20 yrs, looking at drones. Email me pls, <a href="mailto:sdave2393@gmail.com" rel="nofollow">sdave2393@gmail.com</a></p>
<p>&quot;Too high an ESC and you can cook your motor&quot;. This is actually not true. You can use an ESC rated for 60 amps on a motor rated for 20 max amps. You just need to make sure that you don't exceed the max voltage and current ratings for both ESCs and motors. Good tutorial though, keep it up!</p>
<p>well this instructable is great thank you</p><p>i am making two drones. one from scratch and the other from a Kit.</p><p>your instructable really help. cheers mate.</p>
Ok thanks for sharing. I just used the outside ones to try organise them better for myself. Sorry i misinterpreted what you were saying.
I have studyed a lot about brushless motors and used them too, I know very well how the work and why it have three wires. <br>I'm saying that there isn't any difference between the three wires, all of them will be used (alternately by the controller) as positive voltage, ground and sensing, this is how it works. And doen's matter which of them you will switch, you can choose any 2 that it will continue working, with reverse rotation.
In the picture you can only see 2 of the three wires. There should be three when you buy your brushless rc motors.<br>Hope that clears things up.
Hello. Your tutorial is very good, but these names for the 3 wires of the brushless motor don't make any sense. <br>In this kind of motor isn't the definition of positive and negative wires, neither the &quot;signal&quot; that you writed. The three wires are used by the controller as positive, negative and sensing, always alternating these functions. <br>Switching 2 wires will invert the motor rotation.
Two of the motors require a reverse rotation and the other two require a regular rotation. Switching the two outside wires of the motor reverses its direction. The middle wire always stays the same as it recieves a pwm &quot;signal&quot; from the flight controller to the esc and then to the motor. I just call it the signal wire but you can call it a sensing if you like. It's all is the same thing.
Thanks for the instructable, very informative! <br> <br>Keep it up!
No problem. Instructables has taught me a lot of stuff so its about time i gave something back.
