Hello, my friends.

I have often found hobby RC electronics to be of interest in my projects due to their apparent simplicity and ease of use. However, it took me a while to figure out how to put together all the different components, figure out where to get all of the stuff, and read all of the (rather peculiar) ratings when I was trying to build something. Therefore, I hope that this guide will speed things up for you and lead to successful projects.

Quick reference:
1 - Where to obtain parts
2 - Transmitter
3 - Reciever
4 - Servos
5 - Motor controllers
6 - Motors, Propellers and Gears
7 - Batteries

Step 1: Where to Procure Components

After much research, i have found the following to be reliable, have a reasonable price, and have good selection:
 - Hobbyking: A Chinese-based distributor with a huge selection of motors, controllers, and everything else. mostly flying things. Shipping takes forever.
 - Horizon Hobby: Based in the USA, also have a large selection of items, but mostly ground-based vehicles.

There are other, cheaper websites, (like GoodLuckBuy) however I have heard that the reliability and customer service of these is often compromised.
For a complete RC noob, like myself - This guide was very helpfull.
Awesome, thanks!
<p>Very concise simple guide, however I'm looking for a more detailed guide in order to make custom units, mostly amphibious boats, etc..Like how to water proof in case of tipping or a shaft, how to run two different motors at different speeds off one Tx, etc...</p>
<p>I'm trying to add a motor, battery esc, and receiver (Not using steering for now) onto an existing build.</p><p>Do you know if there are any cheap kits I can buy and drop into it? I'm looking around $50 - $70</p><p>A very high torque motor, rechargeable battery is the only real important parts.</p>
<p>I am in the process of wiring three Turgery motors three electronic speed controles to a vosper torpedo boat , some where i found a link on doing this with two motors is to cut the white wire from the second motor so your receiver does not conflict and uses only the one motor to start and the other will start at the same time i tried this on my vosper and i can only get the center motor working tho it only runs for a few seconds could this be the speed controler over heating as they are water cooled so i am just sorting these problems out the way i have wired the motors in three lives three neutrals into one of each from the battery 30 amp fuse on the live each speed controler is 30 amp rated the motors are 25 amp rated these are inrunners (motors) , regarding the white wires is it possible that to get all three motors running cutting the outer two white wires from the reciver was wrong is it possible either the red or black is the wires to cut ? i should be able to sort this out as i am an electrical enineer working on large electric motors and small single phase and three phase units , the only thing that i can think is that each motor is going to need its own power sorce ?right now three power leads from one battery ,three receiver leads from speed controlers to receiver, can you point me why i cant get the two outter motors to run with the center motor , tom yarwood </p>
<p>My first read up on RC Components and it all made sense. Thanks for keeping it simple.</p>
<p>ok guys, stupid question, I want to install a two step on my gas rc car, can this be done?</p>
need help with my electronics.. I have a 30A esc, flysky 6channel transmitter and reciever, and a 3s 11.1 v 30c batt. I successfully bound the reciever and controller, but the motor won't turn, just making a continous beep, heeellllppppp please!!
<p>Hmm, it is difficult to troubleshoot from afar! Check that the transmitter ranges/trim is set to the middle, or try moving the trim up or down - sometimes if you have the stick on your transmitter all the way down, the transmitter transmits a low value but not 0 - some ESCs won't initialize until they get a signal of 0, to prevent the motor from turning unexpectedly. Other than that, make sure you have your esc plugged in to the correct channel. </p>
<p>Very nice guide! Any reccommodations on a budget Friendly, brushed (ha learned something!) ESC? Needed for 3 DC Motors - thank you!</p>
<p>What ESC to get mostly depends on how big your motors are and what battery you are running them off of - Make sure to get a motor controller with the Current rating you need and that is compatible with the S number of your battery. </p>
all my servos are working by the way, just the motor. the month is a 2200kv A2212/6T
Want to buy arduino for rc car and RX and TX set, please suggest some cheap and good website
<p>is it normal for me to buy 2 (8 gram)servos,1 motor 720 kv,a esc,and a 2200 mah lipo battery for 120$?if itsn't i just got fooled(i live in indonesia so it should include a 10%tax)</p>
<p>i think it should cost somewhere around 50-70$ if you buy efficiently, try for local shops ,u may get cheap stuff</p>
<p>so i have an rc boat and on the controller i have to be on a cretin spot on the trigger for the propeller to move. its not even that fast. any help?</p>
<p>I'm going to start building a 4' rc lobster boat. But don't know how big of a motor I'll need any help would be appreciated </p>
<p>NOT near a complete RC tuto ,lacks technical issues</p><p>e.g A drain from a motor&amp;proper ESC</p>
Hey this is kinda new to this but any idea what to get to controll two motors in an rc boat and controll them sepperatly to make the boat turn. Like have only one out of two motors run to turn the boat
All you need is two motor controllers - plug your each of your motors into the motor controller, and then plug the motor controller into the channels you want of your receiver.
Didnt think about that. Do you know of a good transmitter and receiver for this. If so thx
<p>Not sure of a good transmitter/receiver combo, but there are a lot that should do the job. Take a look around on hobby websites like hobbyking and see what kind of controller you would like. </p>
Thank you so much. I knew absolutly nothing about rc and this guide was easy to follow and understand. Thanks again
<p>Thank you SIR/MADAM !</p>
<p>Thanks for your tutorial bro</p>
<p>I've been trying to get into RC stuff, but i don't like buying things when I could make them for cheaper. (I also just like making stuff) this is just what i needed to figure out how to start making rc things.</p><p>I am first going to build a rc boat mount that I can attach to anything to turn it into an RC boat.</p>

<p>&quot;Older, analog TX&quot;? MY LEFT FOOT is analog... Ever since about 1966 that these are known as Digital Proportional - GO READ YOUR HISTORY ON THIS: </p><p><a href="http://www.radiocontrolhalloffame.org/" rel="nofollow">http://www.radiocontrolhalloffame.org/</a></p>
<p>hmmm sounds like 1996 was a while ago soooo his statement still stands.... also this is written for people who are new to this area.... calm your capslock good sir</p>
<p>Always one ungrateful person. <a href="https://www.instructables.com/member/voaferro1" rel="nofollow">voaferro1</a> Go read a book on manners.</p>
This is awesome...it was really good..thx
<p>This is very brief and one page understanding of complete RC stuff. very helpfull. I would definitely vote for it. </p><p>I'm a newbie in RC hobby, <strong>and it's great collection of words :) </strong></p>
<p>how much does all cost</p>
<p>so completed ;-)</p>
Please tell me the rc plane part sizes
<p>Thank you for a very interesting article, however I still couldn't find the small piece of information I have been searching for </p><p>How slow will these motors go, assuming a slow pulse driver is connected !</p><p>It looks as though one of these motors could be modified to have a hollow centre shaft, therefore, they probably would be suitable for driving the cross slides on a small mill, power would be no problem, and it would not be necessary to disengage the shaft before changing to manual mode </p><p>Any thoughts would be helpful, but please don't just say I should be using stepper motors </p>
<p>These motors will spin at a minimum rpm of approximately 100. With some gearing, they could easily drive cross slides, and if you just need a constant feed rate you might even be able to get away with a decent speed controller and servo tester setup. The reason people use stepper motors is that stepper motors have much finer/more controlled positioning (1.8 degrees per step vs about 30 for most rc motors), and the drivers for steppers are designed to step a certain amount of steps rather than maintain an approximate speed as in an rc motor driver. <br>I don't see why you would have to disengage a stepper to use manual feed, perhaps it is because the electricity generated by spinning the motor would fry the control circuits? In that case, you could just add an electronic disconnect switch. </p>
Dear Sir<br>Much obliged for the information, I'm only just getting into brush-less motors, and finding that although there's is a lot of information from the manufactures point of view, it's not much help to someone not familiar with the individual terms ?, (Still hopefully searching for a good helpful book on the subject)<br>Many thanks again
<p>Just what I've been looking for, thanks very much!</p>
<p>I must say, This has to be one of the best &quot;Welcome to the World of RC&quot; posts I've ever read. Thank you immensely for your post.</p>
Thank you, that made my day!
Awesome guide! I am making an RC submarine and had no idea why I needed an ESC or how to connect my servos and motor to the transmitter. Thanks a ton.
<p>Won't radio reception be a problem under water though?</p>
<p>it works to a limited depth. Particulates (salt, chlorine, etc.) effect range, but you can get an average of 6 - 8 feet of reception in fresh water.</p>
<p>An excellent all round guide! Thank you for taking the trouble to put this together.</p><p>There is one area which is still a mystery to me. Namely I cannot understand why some motors have such high current requirements. frankly speaking the motors I am familiar with are those I scavenged from various printers (which are brushed 12 Volt motors which do not seem to require much current but spin quite fast) and also brushless motors such as those used in a cd drive (which also seem to need little current and spin very fast), so when I see adverts for ESCs that can deliver 30 Amps or more, I get a little confused. Could I use the typical CD motor for a quadcopter for instance and if so why are such heavy current demands and dangerous LIPOs needed?</p>
Thanks! <br><br>As far as the motors go, the small cd drive motors won't work because while while they may spin fast, they cannot supply a lot of torque. You can test this by trying to stop one of these motors with your hand: it is very easy to slow them down. While the big, high current motors spin at close to the same speed, they can supply a lot more output power, and therefore more torque. This means that if you try to stop one of these motors with your hand, it is a lot more difficult to do so. In practice, this means that they won't slow down with a big propeller attached to them, and therefore will be able to create enough lift for a quadcopter. The LiPo batteries are in turn needed to power the large motors.
<p>Thanks again. Interestingly I did some further reading and found that apparently there are people who &quot;beef up&quot; CD motors by messing about with their internals to improve performance and then these motors do become useful for quadcopters and so on. But apparently not &quot;out of the box&quot;, except for really small quadcopters.</p>
Sir, I read your article. Liked it a lot. I'm interested in building a rc helicopter. What all extra electronic components are required other than what you've mentioned?
you need a gyro and maybe 2 batteries
Thanks! <br>Are you planning on building a quadopter/multicopter or a real helicopter (single rotor)?
