In this video we cover the how an ESC works and what the main jobs of it are inside your model. We cover the standard settings that you will encounter in traditional firmwares, things like brake, advance, voltage cut-off, direction and timing. We cover a few of the standard firmware types like SimonK and BLHeli. We talk about what OneShot is. We then finish by discussing the various types of battery Eliminator Circuits (BEC/UBEC) found in ESCs (Linear, Switching/switched, Optio/Opto).

Happy flying!
I became a dronemaniac about a year ago and, being a technicaly skilled engineer, I am surprised that every time I watch one of your videos, I learn something new and important! I have to admit...you replaced Netflix on my tablet when I go to bed! Great job and I am watching all and every one you post...often several times!
Glad the videos are proving helpful! Best of luck with the build!
@@Painless360 hi. I screwed up my ESC of no name by wrong calibration with my tx16s radio as I was not aware of the tones. Is there any universal way of returning the single ESC 30Amp to the original setting (factory reset) somehow? How?
Your channel is one of the greatest ones of them all. Very in depth, yet broken down for simple minded folk such as myself. You're a great teacher!
I have watched Painless360 from the beginning....love the knowledge
THANK YOU SO MUCH!!!! I had a Blackfoot about four hundred years ago and am wanting to get back into the hobby with rock crawling. This stuff is all new to me and easy to understand videos like yours are a life saver. Thank you so much!
New to RC Flying, and this was an outstanding beginner's outlook on how ESC's work!! Thanks for taking the time to produce this.
I have returned to RC (20 years of building/flying/crashing planes) after a 10 year lull and have explored multirotors. I have spent a pile of cash teaching myself how to build and crash but have managed to learn basic FPV. Your You Tube video channel is like the University of Modern Radio Control and should be a must for all old timers re-entering the hobby. Thanks so much for all you have taught me!
petwog You are very welcome, you are one of the audiences that this is made for.
Happy flying, welcome back!
@@Painless360 can we use this ESC for RC car
TOTALLY THE BEST, DEFINITION(S) OF ESC I HEARD ON THE TUBE ! AWESOME INFO, NO freaking overriding background music etc., Very Professional in my book! T H A N K S
Usefull video sir! Comprehensive rundown of all important info on brushless ESC! :)
Yet another great video Lee.
Thank you for what you are doing for the community buddy. Without people like you, excuse my french, I would be screwed.
Thank you.
:) WOW! Best ESC explanation ever. Thank you ! A must see & understand for all newbies (me) :)
bekawe2011 Thanks for the feedback! There are a few 'Introduction to..' playlists on the channel that you may find interesting..
Happy flying!
I am working on project using RC motors and ESCs and this was the single most useful video I watched in 2 days of research! THANK YOU!
+lemmonsinmyeyes Glad it helped! Best of luck with the project!
Mr. Lee you are a RC Guru for many of us......Thank you Sir.!!
Thanks Lee , I'll have a swap around before ordering parts . Keep up the good work 👍🏻
Thank you ! So much to learn and things are constantly changing or being updated. Nice to have some where to look to find details in layman's terms backed by real knowledge.
You opened up my eyes and thanks for the in sights. Great tutorial and info.
+Mrinfoone thank you!
Thanks for helping all of us newbies. All your videos are clear, to the point and without the a noxious background music present on too many.
...and, by the way, for people who grew up with 2-stroke engines and 27MHz radios, there’s a LOT to be learned...
There is but the hobby is even more fun now with the amazing tech about. Once you've got to grips with the new digital radios and eleectrics power systems then you'll be back flying. Have a look at the 'Introduction to Remote Control' for more of the basics videos. I'm starting a new series next month that looks at the common questions from 'new' and 'just come back to the hobby' pilots so please keep an eye out for that too! Happy flying!
Think I found my new favorite youtube channel... Your helping make a hobby that seemed exclusively technical, overwhelming, and not accessible to anyone not working for NASA..., into a doable, fun, and educational hobby that will open up whole new areas of knowledge and interest for many people including me. Particularly in today's world,That is as commendable and needed as much as any charity or good deed could be. Good on ya and Thanks :)
+DanielVision Thank you for taking the time to write that! It's always nice to hear we are helping others understand some part of the hobby. Happy flying!
Love your videos. Clear and easy to understand. Very Nice work!
Thank you for the great information given on esc`s. Very helpful. Getting ready to setup an a10.
Learned a bunch. Thanks! Putting together an FMS PT-17 and know almost nothing about today's RC radio tech, especially electric powered, so trying to get up to speed. Used to love flying gas/nitro planes using now-extinct FM radios. Was always worried someone would accidentally turn on 'my' channel 42 and crash my beloved plane. Glad that old tech finally slithered into the tar pits. Gotta say that today's RC tech is freakin' extraordinary!
Cheers from Thailand!
+Jimbo in Thailand glad it made sense. I came back I to RC just as the old tech was dying off. There are lots of basics about current technology in the 'Introduction to Remote Control" series. Happy flying!
Forgot to mention, I started the build of a Hexacopter which I design for high payload and precision flying. Needless to say, your contribution to my project is incredible...I think I will print a small sticker with your logo and stick it some where on the final chef-d'oeuvre!
watching this 2021, and still i have learned so much! your channel is worth gold! ^^
great vid!!! saving me a lot of trouble upgrading my racing quad!
Painless, I've watched so many of your videos, and in terms of explaining things I think you're THE best that I've seen! Keep up the good work! Tom
+Mrkindleify Thanks Tom! Happy flying!
Painless360 what do I do with the red white and black combo wire if I don’t have a port for it on my FC?
Excellent video... not to technical but just the right amount of information to answer the most asked questions... Well done!
Thanks you :)
Super instruction... as a newbee I find your info clear and concise and so helpful, thank you!
+Robert Mulligan thanks for the message. I am glad the videos are proving useful. Happy flying!
I am new to RC and these videos are making it a lot easier to understand. Thank you for making then and please keep them coming.
Robert Blitek Tanks for the feedback. Some good 'Introduction to.." playlists in the channel that may be of interest - th-cam.com/play/PLYsWjANuAm4oWuE5ZDX4TAiHBv2i0Xl4m.html, th-cam.com/play/PLYsWjANuAm4pIU07ta7glYIn-EBCof_4r.html and th-cam.com/play/PLYsWjANuAm4rQfddw-7YZDzckoJ_KyOpm.html

Very helpful and very well explained - thank you.
You're helping me tons thanks for all the great info.
A very informative video and well explained, many thanks.
HI YOUR VIDEOS ARE GREAT .i JUST GOT INTO qUADS AND YOUR VIDEOS ARE THE BEST!
i HAVE LEARNED A LOT FROM THEM AND IAM A OLD TIMER BE VERY CLEAR AND EASY TO UNDERSTAND,
THANKS.
Thank you for your excellent videos and descriptions,the best videos I have seen so far on internet .regards
Thank you. Happy flying!
Being a newcomer to this hobby trying to wrap your head around all the theory takes a f***ing university degree. At some point - usually around here with ESCs and BECs - smoke is coming from your brain and your hair is catching fire but you can't put it out, because your eyes are pointing in different directions. But dont worry, it's all fun and games until you realize everything you watched and read was made back in 2012 and everything's changed since. Yay!
+iMeMySelf stick with it, it'll all make sense. This video is part of a series that's designed to cover the basics and everything in the series is still relevant. Sure, they've been improvements and changes and firmware additions but the basic principles underlying everything are still exactly the same as they were 10 years ago. Best of luck with your journey in the Hobby
Thank you @Painless360 all of a sudden, everything fell in place. You were right, it's weird and I can't explain it but you were def right about going back to the basics. Then updating on progress made since that time is easy-piecy!
This is very informative and helped me A LOT ! Thank you!
You have a great channel. I recently picked up the hobby again after a long hiatus (since teenage years). Now I will finally finish my Tamiya Gepard (with custom gearbox), together with my son! I am so much realizing how much we were in the dark back in the era before Internet and TH-cam! By the way, I now work for one of the leading manufacturers of small DC drive systems, so I have a much more professional angle towards the hobby. Still a lot of fun!
Welcome back to the hobby. A lot has changed in just the last two years. It's cheaper, we have more power using LIPOs and brusless motors, the parts and models are easier to get and repair and you'll need to reach for as PC more often now than in the 'old' days. It's even more fun now! Best of luck with the model and getting back into it all. The series called 'Introduction to Remote Control' may be a little noddy for you but may act as a reminder.. :D
very informative on a fundamental level...thanks
Great video and explains ESC very well.. congrats
+My Drone Addiction Thank you.
Thank you. Great job explaining.
Great explanation. Well done.
Brilliant exposition of ESC control and brushless motors, not into RC, just needed to understand how to regulate a motor - thanks
Brilliant. Best educational quad to-do videos on youtube. Keep on publishing, and more builds. Thanks!
Ja hans bagkatalog af instruktionsvideoer er absolut overvældende. Jeg er også en stor fan.
Another great vid. Thanks.
thank you so much. Very nicely explained.
What a great explanation very good channel 👍👍👍
Great information for us newbies , thanks
good lecture for beginner, like me. Thank you very much
nice. very clear explanation, I learned a lot.
👍👍 from 2017, lok
Outstanding video!
Great video. This discussion is still valuable today for beginning RC wannabees.
THANKyou for providing a timeline index :)
A great video. Thank you.
thank you so much for a very helpful video! happy new year!
Thank you. Best wishes for the New Year!
very well done job, thanks a lot!
I appreciate this video. Thank you.
thankyou for turorial info.im learning
Thanks for another great video . . Your video was just what I needed to know as could not find another video with all the information that you provided
+jacky Parker Glad you liked it. Loads of videos in the 'Introduction to Remote Control' playlist that cover the basics. Best of luck with your project!
+Painless360 Correct me if i am wrong but are you in to RC boats ?
Not at the moment, why?
+Painless360 Just that your YT channel has got to be in the 10 top for RC reviews on YT . . . . Reason I say that is your videos haver been mentioned in facebook RC groups a few times
Excellent presentation
Thanks! Your Video Post are very informative...
Thanks, this was super helpful!
Very helpful, thanks!
as always good inf painless!
You gained a subscriber, great videos!
+Nathan Moody Thank you - welcome to the channel!
Thanks, good work.
Awesome explanation hope you can post the actual happening on that diagram 👏🏼
Really great video, thanks! I have a question. I have linear escs. Do I have to connect all four 5v to the cc3d or can I just connect one and use the others for lights and stuff? Are there any benefits in connecting them all to the cc3d? Thanks again!
So the eachine 250 racer has opto simonk esc,s. It has his own bottom plate for pdb. The flightcontroller gets 5 volt from the pdb. In my case of the not turning left front motor that actually works and esc. Can i take the signal wire and plug it directly in the flightcontroller? It would be a waste of course of the pdb , but i want to know if the pdb is the cause of the issue i am having. Could i hook it up like this to see if it wil turn? Bypassing the pdb? Or will i be blowing something up. Ordered a new pdb board but if that does not work maybe its the flightcontroller. And i have to order that to. For configuring the esc,s in cleanflight the sounds go crazy all over the place. Not standard 2 beeps. The motor stutters.
Thanks for the video
Thank you!
Great vid cheers
Thanks for the great video!
Any idea why I would need to calibrate every time I change batteries?
No, that shouldn't happen.. I'd check to see if others with the same ESC have had similar problems. Best of luck!
well done bro liked and subscribed!
+Shinra Kitsune welcome to the channel. Best of luck!
Hello, thank you for yet another excellent video. Even though I have used them for years, it clarified my understanding of ESC's, especially the significance of SimonK. I do believe there is one thing that you could add to this video which I still don't quite understand. That is the difference between 'Rapid' and standard ESC's. In Open Pilot, one has to choose the type of ESC (as shown your very well done CC3D videos). Can any ESC be a rapid ESC? Are they special? Are they something we should aim for? Can a firmware change make a standard ESC rapid? Everything else about ESC's you have explained so clearly. Just a thought.
very helpful. 😊🙏
Thanks greatly
Hi. It is possible to use racer ESC to run big motors like an Emax MT3515 650kv? There are some big ESC that are 40 amps and this little ones that have 40 amps too but in a tiny and weightless formfactor, can I run them without any damage with those big motors? I try to find this on internet but never find something. Thank you!
So helpful thanks!! (:
Very good video, schooling a thirty year electrician.
You Rock!
Hi! Great video and great explanation!
I’m currently building a quadcopter using an APM 2.8 and maybe you could help me solve some questions I have. I have LD Power ESC’s with NO BEC’s. Does that mean that to power the APM I should leave the JP1 INSIDE to power the whole APM with the 5V the power module provides and leave the power cables from all of the ESC’s connected? In that case, will those 5V the power module provide be enough to power the whole APM or could I have voltage shortage problems, or over voltage problems coming from adding the power module voltage and the ESC voltage (with no BEC the ESC’s should not be powering the APM at all, wright?)?
Thanks in advance!
See the power video in our APM series for the answer to your question. Best of luck!
I'm a bit unclear on the OPTO ESC's. I was planning to use my OPTOs for motor only and using a separate 6V batt to power my servos etc. Do I need to use a separate BEC or can I just plug the 6V battery pack into my receiver BATT slot?
Thanks for these videos, I subscribed.
I didn't ask but I really needed to know this ;-) so thanks
Nice video. Thanks. Btw, you sound like Jack Frags
Have received my skyfun todaty with a 25Amp linear esc bec but i have no idea how can I use a separated batery in order to control telemetry in one side with its own Bec and the motor and throtle in the other ... do you guys have a video showing how to use 2 separated batts for tha5? Thank you ;)
nice explanation, i have questions do we need one bec for each esc ? and is the function of bec just to powering the flight controller ? thanks
The ESCs provide their own 5v power to run the on-board circuitry so the BEC output from an ESC is more to allow other things to be powered from that 5v supply..
Wow this is so useful! Just in the middle of building a scratch build wing and having clicking noises and warm motor, using a traditional esc type. Looks like the timing is my issue?
Very possibly. Best of luck!
Which way up are the 3 wires on the connection from the ESC to the Naza Mv2 main controller? My new speed controllers have Black Red and White wires to the connector. My old ESC's had Brown Red and Orange with the brown uppermost.
Yellow and white are the signal wire, Brown or Black is GND.. Best of luck!
Thank you for stating that these "brushless DC motors" are actually 3-phase motors (synchronous 3-phase specifically). I'm both an RC pilot and an electrical engineer so the "DC motor" false identification has always sort of annoyed me. I speculate that half of the hobbyists don't know and care. But the other half wants to learn and understand. Giving them the accurate information reduces confusion . Thank you 👍
Hello Mr. Painless360, I've got some Optio ESCs (emax 40A) and trying to understand how to setup.@18:18 you say something about an "incoming rail". What do you mean? I just cut all the red wires from the ESCs to the flight-controler and then power only one of them on the side into the flight-controller from a seperate ubec, right?
Thanks for the effort you're making with these videos, much appreciated.
Hey man great video tutorial very easy to understand, so thanks. I'm thinking of building copter but with a difference, I want to build one with 3 lift motors and two propulsion motors. So in otherwords 3 motors in the y axis and and 2 in the x axis. I'm just getting up to speed with ESC etc and wanted to know in principal would it be possible to control this set up and how one wuld go about wiring it? All help gratefully received
+tim lazenby not sure, I've seen other development models that use a similar setup though.. Best of luck!
nice explnation
Is a brushless flight esc usable in a rc car with two Motors?
Like the old wild dagger from tamiya?
Because there is only brushed dual motor Controller for cars i can find.
Is it possible for brush esc to block other channes on reciever? If not, why does this accure?
I used 10A IZushed Reverse
+gregor sokolovic I've not seen that, best of luck with it!
Another great tutorial, thanks!
I have read in a couple of places that Switched BECs provide a less clean supply when compared to Linear ... which may cause interference when powering FPV equipment. Do you agree?
+zoso12 The output capacitors and smoothing circuitry is normally well up to the task of smoothing the 5v output to be silky smooth. I suppose those that use smaller caps and lower quality components may have problems but I've not seen it..
Fantastic video !
Hello Painless and thank you for the very informative video on ESCs.
I do have a question. I have some 30Amp ESCs, Simonk, and are rated to run on 3S batteries. Can these ESCs run using 4S batteries? Any insight would be appreciated. Thanks.
If it's not rated for 4s then you run the risk of overloading it.. Best of luck!
Yup fascinating cant wait to play with some of these. Problem Im finding, everytime I watch one of your videos I buy some parts. Im not going to this time ...... Im gonna wait till tomorrow. Solution!
Sorry about that ;)
I used 30A ESC and a 3S lipo battery in my quadcopter. After arming the motors a strange beeping sound(1 beep) was coming from the esc s and the motor did not run when I turned on throttle. What should I do? Can you help me in this case? I'm using sp racing f3 flight controller and using i-bus connection. Actually I couldn't calibrate 4 escs at a same time with i-bus connection. Do I need to calibrate esc individually?
And do I need esc calibration every time after first calibration?
I want to get the complete step by step procedure in setting up my Flysky FS CT6B to control a Sabertooth motor driver for 2 wheelchair motors. After I purchased the Flysky system I discovered not everything I needed to make it work was contained in the box. I became aware that I needed a separate power source for the receiver. Then I became further confused with ESCs & BECs. I'm talking about connections, current requirements, etc. My Sabertooth driver is dual 32 amps.... This all new to me.
+William Gunter all of the basics for radio control, when it relates to radio control models, are in the 'introduction to remote control' series here on the channel. This video is part of that series, hopefully the other videos will help. Best of luck
does the ardupilot apm 2.5 mega come with a built in esc or should it be attached separately
Aditya Nair please see our APM series on the channel, we cover it all in there. Happy flying!
I have a question pls, if I have a 20A Esc, I can supply that with a PC power supply that give me 12V and 23A?
I don't understand what you are asking. You shouldn't try and pull more than the rated amperage from an ESC..
in outline to FCB (Flight controller Boadr) they esc always have 3 line cable, is Bec Output , Ground and PWM input. so how with if the ESC just have 2 line. (Bec output & Ground) no line for PWM input. can i use this or how to do, ???
Those ESCs that have no third wire are called OPTO and the two remaining wires are PWM signal and GND.. Best of luck!
