For this instructable i will be showing how I scratch built my own quad-copter!

Step 1: What Shall It Do?

The first thought you have to think before even purchasing a single material or part is what do you want it to do? Do you want something that is fun to fly? or maybe take some aerial photography? Maybe a combo of both? Either way this page will give a breakdown of the pros and cons of each multi-rotor craft out there, but first two of the biggest rules about brushless motors.

Rule 1: Brushless Motors are twice as efficient than brushed on lower power levels(under 65%)
Rule 2: More Motors means more power and more lift!

Tricopter: The little baby brother of the multi-rotor family. Its one of the easiest to build and the cheapest to build, however when it comes down to performance its motors take the most strain because they are running on a higher throttle than any of its other siblings leaving it with low flight time and low lift capabilities. 

Quadcopter: One of the most popular craft in the multi-rotor family. Its a little more challenging to build and a little more expensive. The quad is only a couple grams heavier with the extra rotor but that extra rotor gives the quad a huge boost in lifting capabilities and flight time. If a motor fails though the whole vehicle will go down. 

Hexacopter: In-between a quad and an octacopter. It can be difficult to build and more expensive to make and it also takes more ground prep time then the quad or the tricopter because it tends to have multiple batteries. It can carry a much heavier load than the quad can but it may require 2 batteries to achieve the desired flight time you want from a multi-rotor. Even if one of the motors fails you will just lose yaw control of the aircraft but manage to stay flying. 

Octacopter: The big brother of multi rotors. It is the most challenging and the most expensive to build. It can take the heaviest load for the largest payload you want on it and can have up to a 40 minute flight time. Before flight it can require a lot of prep work as some octacopter a can take up to 4 LiPo batteries. 
good to see ur drone<br> is there any making vedio of it
Which motar is required to lift 2kg of weight..(MAX)
Can we use an arduino uno for this ?<br>
I dont get it can you teach me pleas
<p>A lot of time with these is spent Hovering. How much power would it save if you built in a helium bladder to make the drone almost neutral buoyant? </p>
<p>Maybe if you had a huge helium container, but it will need to be huge, so idk if it is practical enoth. try it.</p>
<p>Nitrogen would have more lift. Weighs 5.31lbs per 1,000 cu ft compared to 10.54lbs for helium.</p>
<p>Hi! correction you mean Hydrogen not Nitrogen... Hydrogen is 5.31 lbs per 1000 cu ft... Nitrogen is 72.448 lbs per 1,000 cu ft</p>
<p>Light but flammable. One spark and the whole thing explodes. You'd get a heck of a bang from it. It is easy to make though (a giant exploding whale with rotors comes to mind). That being said, if someone can pull it off I'd love to see it.</p>
<p>That would then be called a blimp :) I have thought about this also, but wind would be bad for it. Maybe spread it out to a large disc so it also serves as a wing type lift when moving.</p>
<p>If you do this, post results here! I'd love to know how it works out.</p>
How about carrying a human?

<p>what is the mean is 850KV motor kilovolt or other??? </p>
<p>Kv on motors is how fast the motor turn per volt you run it on. So it means revolution per volt. for smaller copters you want at least about 2000 kv and for larger ones under 1000 kv. The lower the Kv, the more torque the motor has and can turn larger props. So small copters with smaller props like 6 inch will need spin faster with higher kv motors.</p>
<p>what about programming ... how will i program my quadcopter</p><p>and are there any cheaper options than using aeroquad</p>
<p><a href="http://www.Hobbyking.com" rel="nofollow">www.Hobbyking.com</a> look for hk2 flight controller. This has many model types already programed in and you can adjust parameter with buttons in the field.</p>
What is the flight time with say a 250 gram load.
<p>5 mins, tried it</p>
<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>i know that the ardupilot is based on a adruino atmega 2560</p><p>so if you buy such one with a i/o shield you can save up to 180$</p>
<p>Can I have the links to where you bout the electronics? I have the motors, frame, and card so far.</p>
The motors are cheaper at amazon.com You can get the complete set at $94.680
<p>You guys are doing wonderful jobs. I wish I could actually adorn Charlottesville skyline with one in the nearest future. You can inbox me for easiest guide : Dianawalmer@outlook.com </p>
Really nice
Really nice
<p>can we make at home ??????</p>
<p>nice ..and can you send me cordcopter pcb design and pics only on pcb circuite plzzzzz and my email is m.dasadnaeem@hotmail.com</p>
<p>I net to do somthing fly for my school and a don't now what to do </p>
Very good! Any thoughts on using dc motors from common dvd and vcr parts?
<p>i wish i can build that ,,,, unfortunatly i cannot ,,, so i just gonna say nice tutorial</p>
<p>Hi so i was wandering how could i adjust this so it will just follow me? I want to be able to get it out press go and get it to just follow me from about 10 feet? </p>
<p>To do that, you'd need some sort of small beacon device to strap onto your wrist or whatever. I'm not sure about the details but you can read about it here:</p><p><a href="http://www.gizmag.com/airdog-auto-follow-action-sports-drone/32576/" rel="nofollow">http://www.gizmag.com/airdog-auto-follow-action-sports-drone/32576/</a></p>
<p>hi,</p><p>i am sarthak sethi from india and i am very interested in making a quadcopter. I followed all your instructions, but now i am stuck up with a problem. I am not getting how ans where to connect the receiver to the setup..... plese help me???..</p>
<p>flight times, please. With load, without load, hovering, and continually moving, if you could please</p>
hey which motors did you used? <br>and can I get that online?
<p>but i dont have all the motor as same,i have 2 pair and both r different </p>
<p>Most of the blogs/website say we need minimum of Four channels for a quadcopter (pitch, roll, throttle, yaw):</p><p> 1. One channel for throttle</p><p> 2. second channel for turning right and left.</p><p> 3. third channel for pitching forward and backward.</p><p> 4. fourth one for rolling left and right.</p><p>[Radio Transmitter Image](http://blog.oscarliang.net/wp-content/uploads/2013/10/5-channel-transmitter-diagram.gif)</p><p>But looking at the RC transmitter , i see that at a time you can change a maximum of two sets data ( left and right joy stick) . Even if you want to send Rudder and Throttle information at the same , can it not be sent in the same packet ?</p><p>My understanding is two channels should be sufficient to control quad copter. Please provide more clarity on this.</p>
<p>you have a diagram of your circuit please... <br> I could send it to my email?.. cristian_ochoa11@hotmail.com</p><p>I am from mexico</p><p> I will be very grateful :]</p>
Which cells are you using
Great looking quad. Curious about the acrylic sheets you used. Were they stiff enough? And where did you find them for $0-$5?
not quite, id rather have them a little bit stiffer. I found scrap acrylic and they offered them cheaply to me
I didn't read anything about getting the thing to fly, or the adjustment / programming of the auto gyro stuff. <br> <br>244 Jake
I'm not sure if you had a reason to leave all the wires wrapped loose like that but there is something you need to know about aerodynamics. Almost nothing creates drag like a cylinder. Your mesh of loose wires is a very efficient drag device. If you use the quad outdoors the wind will &quot;catch&quot; on those wires and carry the quad away very easily. Or you will drain unnecessary power trying to fight the wind and keep the quad where you want it.
Absolutely fantastic 'ible. I love it.
hello. what motors should i use to pull up alot in the air a go pro camera?
The motors on it now can handle a GoPro easily. If you want to put some of those $1000+ cameras id recommend going with a hex or an octa because if a motor gives out on them they wont drop it
No i will just use my Hero 3 camera, i paid for it $300. I would like to to aerial video of my riding, because I ride motocross. And some aerial photos of landscapes and other things, but i need something that will go alot in the air, and maybe i will put an exploding mini parachute for it, so it doesn't wreck if something fails.
Nice job. I'd put the ESC's on the arms with cable ties and shorten some of the wires to tidy it up a bit. And you could make it even cheaper by using KK2 instead of APM, it's not got all the bells &amp; whistles of the APM but would do well for someone just starting.
yeah i only had a 2 week deadline to build it and very limited supplies so i didn't get the chance to make it nice and tidy. I just wanted it flying lol
