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).

what are the hz in esc?
Your videos have helped me with my first build…thank you for making them. Is there a reason everyone puts the battery on top of the quad? I would think underneath would put it nearer to the center of gravity??
What’s the frequency these motors run at? I’m planning on building an ESC but without all the fancy features. just to run a motor.
Great video! I was thinking on using an ESC to control a cordless drill motor, but this motors only have 2 cables, what can I do? Do I just ignore one cable and use the remaining ones?
Greetings I bought an ESC that is labeled 2-3 S Lipo, so what type of battery I must bring 2S or 3S?
Thank You
if you get a motor you can just stick it to a battery and it will work
Hi , Im using the naze with a little bees 4in1 esc , foxeer camera and foxeer switcher vtx . The picture is very grainy , I thought this was noise from the wiring but I’ve tried an LCfilter with the naze and also just changed the board to a furious radiance with built in filter and still the same problem , any help would be appreciated. Thanks
Hello. I’m intent on using an RC motor in a project and have a 12V power supply and a PWM all set to go. Is it possible to connect a brushless to the PWM without an ESC or is the latter a must for brushless? If so, what motor then can I just connect to a PWM in just cutting the wires and attaching it? Your diagram and animations are informative BTW ‘cos I’m learning as I go with this stuff.
Hey I was out with my rc truck last weekend and it was running awesome then all of a sudden it tales off buy it self first foward then reverse, I shut it down and turn it back on and it works fine again, the later that day it was running fine but the battery was dead. It was sitting on a table after I put another battery back in and was smoking a cig when it took off full throttle off the table and started turn g really slow left then right then slowed down to about half running speed all by itself then it all of a sudden Started listening to the remote I was holding. anyone have a idea on what I should start looking for?
I am trying to program (using transmitter) a green Turnigy Multistar 30A ESC (480 Hz 2-4S with 4A SBEC), and I succesfully get to the point where I hear repeating 1 beep, 2 beeps, 3 beeps etc. But when I move the throttle stick down in order to enter the submenu, it just beeps once and that’s all. If I move the stick up again, it immediately starts the motor. What am I doing wrong? It works fine otherwise.
WooW Good Job 😉 Crack
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 Youtube! 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!
Together with a colleague, I am looking to drive my tank with two BLDC (outrunner) motors (one for each track). We may use an Arduino to make a “digital differential”, like some of the Tamiya DMD controllers. We’re still in the early stages so I’m now exploring the current state of technology of RC, which your channel is proving to be of great benefit. On my channel there is an animation of the “Cletrac” differential, which is a very nice mechanical concept, although hardly suitable for RC.
hey mate, can you make a video about what kind of pwm signal do i need to generate with custom circuit for running esc?
That’s a little beyond me but if you Google for ‘PWM Arduino libraries’ there is lots of detail that will help.. Best of luck!
can I use an Esc 6S With an engine 3S?
ESCs and motors are not usually rated that way. See other videos in the ‘Introduction to remote control’ series for more power basics. Best of luck!
It’s me again …. I was wondering if I can use 30amp and 25amp or even 20amp ESC’s (from the same manufacturer and running SimonK) at the same time? I have now built a hexacopter and running out of places to buy my old 30amp ESC’s that keep failing.
thank you very much it’s really really best explanation????????????????????
I would like to ask you what ESC would u suggest for my quadcoptor , I just started making my DRONE
thank you very much it’s really really best explanation👍👍👍👍👍
I would like to ask you what ESC would u suggest for my quadcoptor , I just started making my DRONE
+mourya vamsi see the ‘Quadcopter building for beginners’ series for that and more! Best of luck!
+Duane Morris I wouldn’t. Best of luck!
i have a question, it is possible to use a blheli esc on a lower kv motor, i have a fairy 20amp blheli esc, i am planing to buy a racestar BR2826 1250kv motor for 450 or 500 build,
+Jogene Aquino if the motor current draw with the props you plan to use is less than 20A then it should.. best of luck!
is there any difference between HP simonk and simonk?
SimonK should be SimonK. I’d ask the vendor if there is anything ‘special’ about them. If you’re looking at multirotor then BLHeli and BLHeli_S are the current flavors of the month..
Painless360 thank you so much!
Interesting but it’s not completely “Basics”. You have stepped over an information that is still not clear in my mind. What ESC are actually doing from the throttle signal? What is controlled? Speed, current, torque, PWM? Is it possible to set a speed limit of the motor? These controllers do not work like industrial drives and this is confusing for someone not familiar with RC, even an engineer like me. I can’t understand the absolute lack of information in the manuals of these products.
Bottom line – you don’t need to know that level of detail to use them effectively. You calibrate the ESC so it knows what no and max throttle looks like. Electric motors are constant speed devices (hence the rating in KV) so the change the ESC makes is to the duty cycle of the high frequency pulse that it uses to power up the next phase of the coil. More throttle = more ‘on’ in the waveform. If you want to get into detail then there are lots of good detail in Wikis and the forums. Best of luck!
Thanks. I understand what you mean. But I have a non standard project (non RC) similar to a EDF jet plane at high rpm. Since they work in duty cycle, it becomes a bit tricky to figure out what will be the maximum possible rpm. If I miss the rpm target by 10% I destroy the motor. My load will also be variable by a large factor. I suppose this kind of condition may exist with RC cars or boats when they leave the ground or water during a jump, then I wonder how they prevent overreving the motors if the ESC does not control (limit) the speed at all. No load, then very little current and much higher available voltage at motor phases which translate to higher speed.
hey! Should i be able 2 use this motor with a 80esc?
Yes, I’d use a slightly larger ESC for safety. Happy flying!
do you have to have a bec or can u run opto only
Hello, Mr., Would it be reliable to use this motor with a 20A ESC and how could i determine the correct working period of a motor?, I’m trying to control it using PWM signals. Thanks!
Should be, see the other videos in the ‘Introduction to Remote Control’ and the first few series of ‘Quadcopter Building for Beginners’ for more tips on this subject. Best of luck!
Sorry to pop your bubble but your explanation of the ESC is only half or less the truth. The ESC receive PWM(Phase Width Modulation) signal from the flight controller or the receiver. Then according to the PWM it generate a 3 Phase sign wave signal of variable frequency that determined the speed of the motor. The Motor is an inductive load and any inductive load have a destructive high voltage EMF, that is then filtered out by 3 diodes in the speed controller. The three phase is 3 sign waves where there is always a phase shift of 120 degrees between the three phases.
+Chris Bezuidenhout it sure is, its designed to help those new to the topic find their feet. If you understand that much about ESCs already then you’re not the audience this was made for. Happy flying!
Hi! Can i us a 60a ESC:
with this motor?
Thanks!!
Motor is 46 Amps max and that’s less than the ESC so it should be fine. I’ve not used those kinds of motors here though. Best of luck!
Painless360 Thank you! Also can i use 3 ZIPPY batteries:
with all of that? I will connect them in series
I’m trying to make an electric longboard 😀
Hi I want to use a USB battery pack 5V 2.4A, can I plug it in directly into the servo tester or do I need some kind of voltage regulator in between?
So long as it’s 5v then you should be fine! 😀
Painless360 awesome, the reason I asked was because, I had a HJ digital speed tester and it blew from the 5v power supply, i was wondering if it could be the 2.4amps, but in theory it shouldn’t be, right?
Hello:
I would like to now if you have some video about the Evvgc 1.3 gimbal controller or if you know what is the best gimbal controller in 3axis.
Thanks and great channel
Sorry I don’t. I don’t use a lot of Gimbals here but the nicest one I’ve used is on the Nova Pro review series. Best of luck!
Hi painnless just build my first quad credits given to you in my description . Thanks for all your help
Happy flying!
Well… good explanation of ESCs but no mention of how to match it with battery and motor, what values for matching and so on
+TheBlackestImp see the other videos in the introduction to remote control series for all the basics..
thank you. I’ll do it
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!
how do i know if my remote control is compatible with the esc
+Joshua Huang if you’re new to the topic then have a look at the videos in the ‘Quadcopter building for beginners’ series’ on the channel, I cover a lot of the basics that should help..
ok thanks
What if i dont have a remote controller.. can i use motor+esc+battery+a simple switch(instead of remote control?) Plz plz plz tell me can i use such setting?
Coz i wanted to built a motor powered bicycle and i m totally unknown of all these electronics and cant use remote for that…

+Herbal & Halal Unani Medicines nope, it needs a PWM signal. You can get an Arduino to create one…

its my little bro scouter from the go-nots. 😉
The throttle setting controls what exactly in the ESC? Is it RPM? Is it voltage? What happens when the propellar spins faster than the throttle setting (lets say you have a variable pitch drone doing a dive and the upward winds make the props spin faster as gravity makes the drone accelerate pass terminal vel).? Will the motor try and slow it down?
+RoboticSolutions.TECH an electric motor is actually a constant velocity device. It will try and maintain a constant RPM irrespective of the power supplied. That’s what the KV is all about it – tells you how quickly the motor will turn for the voltage applied. What the ESC is actually changing is the duty cycle of the waveform that sent to each of the motor coils in turn. The throttle signal increases the amount of ‘on’ vs ‘off’ voltage the each motor phase gets in a high frequency waveform. There are some excellent videos and articles online the explain this in a lot of detail. Best of luck
Please dont wish me luck and send me on my merry way yet. You didnt answer my question. If wind pushes my propeller to spin faster than usual at the specified throttle setting so that its RPM is way above what it normally would be, would the ESC and motor attempt to slow down the RPM? So lets say I set my throttle to only supply 1 volt and the engine is a KV1000. But I put my variable pitch quadcopter on a dive with negative pitch so the propeller now spins at 2000RPM without changing the throttle setting. What happens? Will the Engine and ESC supply negative torque to try and slow it down or will it keep pumping 1 volt in to re-enforce the 2000RPM spin? Or will it just supply no voltage at all?

+RoboticSolutions.TECH no idea, ive never used an ESC in that way. Let me know how it goes..
Can you recommend me a software to monitor and record the current flow?
Why is there no Current / Amp Capacity printed on the motor ??
Sorry, this is outside what I do here. Best of luck
See previous answer – no need to post the same thing twice.
I want to practice autorotation.
can i use a 3s battery on 6s esc and 6s motor?

how do you actually control the speed? i gathered that you use a remote control but how does that connect to the esc
+Rohan Gandhi see more of the basics in the other ‘Introduction to Remote control’ series.. hope that helps gets more of the basics answered..
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!
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!
Glad the videos are proving helpful! Best of luck with the build!
nice explnation
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..
hi don’t know how this happened on my diatone gt2n but there is nothing for number 1 esc on blheli_s no info just blank, can it be replaced I’m a bit new to blheli so don’t know what to do
thanks paul
If the ESC has power and the data link is connected then there could be a problem with that ESC.. I’d be tempted to swap two of the ESCs over on the flight controller in case it’s the output on the FC that’s at fault.. Best of luck!
Fantastic video !
What a great explanation very good channel 👍👍👍
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.
Can you calibrate throttle with motors on your vehicle also?
+Andre Campbell not sure I understand the question, but you should always calibrate your throttle once you have everything wired up. Hope that helps
I dont really know much about esc’s.. Is it safe to use 30amp esc to a 2280kv motors?
See the other videos in the ‘Introduction to Remote Control’ series that this is part of, it’s all answered and also covers how you figure it out for future.. Best of luck!
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
(At the risk of sounding like a know it all…) At 3.40 you say “apply power to the red wire and yellow wire to energise the electromagnet in the can”… Half true, but the yellow would need negative rather than “power” in order to work and complete the circuit. positive into both sides wouldn’t do anything apart from short circuit. The motor is fed an AC like all 3 phase motors.
Not that I’m splitting hairs here. I watched the video to learn myself!
This is a video to help explain the basics of how an ESC works, not get into the detail of how a potential voltage is used to create a current in a conductor. Adding too much unnessessary detail often makes a video too hard to follow for those unfamiliar with a topic. Teaching and passing on information is about making the subject understandable and this video is designed for those with a very limited understanding. Please subscribe. 😉
I’m looking to use one of these in a tandem coaxial helicopter. It’s powered by 4 motors, anyone know if something like this would work?
Depends on the model really. I’d look in the forums for other who’ve made the conversion successfully. Best of luck!
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 vid. Thanks.
55 people are still ESC clueless. 😄😃
What ESC I need to use if my voltage is 24v
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
Hi can someone please help. I’ve had 2 motors failed on my xdetect 360, which I have replaced and now it’s flying again
But the drone wants to fly off to the left. How do I test weather the esc or the main board is at fault
I was very confused by this video, until I eventually realised that it was in fact an inrunner motor that was being used for the demonstration. I have only outrunners, and altho the principle is the same, everything is round about …
Has anyone converted a blower motor (brushless) for a car’s AC/Heating system to something that can be used on a drone or RC aircraft? If you have any experience with this, please get back to me. Thanks.
my simonk 30A esc overheats in seconds even when my motor is not running. please help me.
All bad like there is a short somewhere.. what troubleshooting have you already tried?
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!
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!
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!
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!

I wouldn’t use LittleBee ESC’s for those motors, all of the listings I can see for that motor in the quick search I did were using things like the HobbyWing 40A ESC. Maybe that’s part of your problem. I’d also look in the forums to see what other pilots are using successfully with those motors. Best of luck!

Hello sir, i have an bldc motor having maximum current drop is 24A at full throttle, so what rating of esc is suitable for me? What happened if i use 40A esc? And i had little confused in constant and brust current. Thanks
Having the rating of the ESC more than the motor is a good thing. Burst current is what the ESC can supply for a few seconds without damage and is usually more than the constant current rating.. Hope that helps..
Can i use 40a esc? Is there any disadvantages to the motor? Thank u for quick reply
All covered in the videos in the ‘introduction to remote control’…
Amazing video, Thank you. Could you possibly have the time to check why my motors are behaving like so. It happened suddenly and I have tried almost everything. Here is the link
Without more detail it’s impossible to offer any advice. Happy to help but please watch and come back to me with more detail of what you’ve tried..
My motors are 1306, 3100kv brushless
ESC are 20A BLHeli
Controller is Naze32 rev5
Frame is 3D rpinted
Lipo battery 3S, 70C (1300mAh)
RC is Frsky with receiver fs-iab (using PPM)
Everything was working fine but the next day 3 motors are spinning 4 times and the motor beeps once and when i drag the throttle low it beeps again. Things I tried:
1) Charging the battery
2) Swapping ESCs with motors ( good motor seems to always work with any ESC, but bad motors dont)
3) Applying oil to the bearings
4) Swapping all the wires and the motor orientation
5) Flashing the controller and setting everything all over
6) Testing the motor and ESC by direct connection to receiver.
7) Testing the motors at cleanflight
PS: Sometimes when I play with throttle (up down up down) the motor briefly works well and then after applying low throttle goes back to its glitching. I went to get new motors online and waiting for it, because I think the motors just went bad. I would appreciate your help. Sorry if this is too long!!!
I have these Tarot 40A 2S – 6S ESC OneShot & SimonK Firmware with 5V BEC – TL2953, the specs say they are linear but you mentioned that linear are only for 4S Lipos. I have 6 of these going onto my Tarot 680 hexacopter, so now I’m a bit worried as to the suitability of these ESC,s.
They will be fine but I’d not use them to provide the 5v the flight controller and pieces need. I’d power it using a dedicated 5V BEC.. See the other videos where I cover this in the ‘Introduction to Remote Control’ and ‘Quadcopter building for beginners’ too..
many thanks, I’ll take a look at your videos, my tarot build has turned out to be a bit of a nightmare, but at the same time a very interesting learning curve. Thanks again.
I am trying to build an Arduino Uno controlled quadcopter, there is some confusion about ESC update rate though. My control loop is capable of refreshing every 5 ms, so 200 Hz, but as far as I know the refresh rate for the ESC pwm signal is 50 Hz. While running my program and just refreshing it with 200 Hz (I am using writeMicroseconds() function on Arduino) my ESC’s don’t work smoothly or eventually stop. I am using HobbyKing 20A ESC’s.
Is it possible to refresh the ESC signal to a faster rate than 50 Hz or is this the rate I have to with? I keep seeing discussion about 400Hz ESC’s, but have no idea what kind of input signal do mine accept. I’m also considering trying out sending the ESC signal every 4 loops (5ms*4=20ms), but don’t know if it would have any positive effect on control quality.
I had also read that SimonK firmware “Accepts any PWM update rate (minimum ~5microseconds PWM low time)”. That sounds like it would be perfect to me, but there is so much confusion around this topic that I prefer to ask before screwing my ESC’s. Would that work out right for my problem?
No idea sorry, I’d personally get a look at the MultiWii code as that will have the ESC code in there and you can see how they did it. Best of luck!
I am building a Big Turtle with lifting body . 60 cm from motors to battery, which end would you advise putting the two ESC ? Thanhs .
In the best air flow you can find. The received wisdom is to make sure that the longest wires are the ones that go to the motor rather have longer wires going from the ESC to the power distribution board..
Fantastic explanation, thank you for taking the time out to make this vid!
One question I have is, what type of ESC should I use when using a standard 12v automotive lead acid battery as a power supply? I want to run an EDF using manual control for speed/thrust adjustment so I figured a servo tester connected to an appropriate ESC should do the job as I can use the manual mode potentiometer to control the speed but what about the battery type? Is this going to be an issue?
Any standard ESC that supports a 3S LIPO should be fine. The ESC doesn’t care about the battery type, just that it is the right voltage and can supply the current it needs.. Best of luck!
Great video!
Btw your rotor is oval haha…
Ah yes I realise now what the 2S, 3S etc…. represent, that was the part confusing me voltage/amp rating. Thanks again 🙂
your videos are great.
question i got A 35A Brushless ESC what does 35A mean does it mean it can handle 35a from a battery
or will it give 35A to the motor the motor can handle 37A

It means that it can supply a maximum of 37 amps continuously so you need a motor that needs less current so that you’re not running the ESC at 100% and stressing it. The ESC will pull the amperage (current) from the battery as needed.. See the other videos on the ‘Introduction to Remote Control’ playlists for lots more of the basics explained for new builders and pilots. Best of luck!
ok ty so i can use a 160A esc on a 37a motor

Great tutorial video my freind. Q: can you tell me what ESC should I get for my 4pole 3650-5200kv motor using 4500 3s lipo 😳🤯😫 I got a cheap 120Amp ESC for £15 and it burnt out on its first run. I was lucky to be right there when it happend or I would of wrecked my car. Please can you help me. 🤔??
Look at the amp rating for the motor and get an ESC with a higher rating.. best of luck!
Thanks brother helps alot. 👍👊👍👊
im looking for a flight controller with built in ESC`s say 20a do you get them ? if so what’s the best
You can get All-in-One (also called AIO) flight controllers but I’ve not seen one that has the ESCs in as well. I bet they are out there though! 😀
Show me the size of esc of a jambo drone which carry man
No idea. Happy flying!
Thank you!
Which esc use for 1000kv racerstar motor ???
What is the max amps in the specs for the motor you’re looking at? You’ll need an ESC with a equal or higher capacity for the current with the prop you want to use..
Painless360 …1000kv motor with load current 15.6 A.so can i use 30a esc for this motor?
That would work well. You could get a 20a ESC if it’s only that much..
You sound exactly like Matt Parker from standup math
I think you’ll find he sounds exactly like me 😉
Hey, thanks for the great vid. I’m looking for an ESC to connect a 24v 2.2amp DC brusless motor to a PWM controler. I can’t seem to find a suitible ESC. Most are rated for much lower voltage. Am I missing something?
Cheers!
Maybe, support for 6s batteries is common…
Painless360 My power supply is 24v DC.
Sir i have 1400kv motor, can i use 30A esc?
If the propeller you want use with that motor pulls less than 30 amps, then yes that will be fine.
Great video. I’ve one question. Can I use those ESCs in a e.g. airboat? I know, I’ve to make them waterproof. But can a combination like a RadioLink EC6GS remote with a 6 channel receiver and a e.g. Yuki Wasabi Eco BL-ESC 55A ((DE+EN).pdf) if I switch off things like govemor mode and break?
So long as the current rating is high enough for her motor and prop you’re using then yes. You can waterproof the esc using one of the waterproofing sprays or epoxy too..
Thx for your help. That sounds promising. Great work and I guess you have a new subscriber 😉
My esc is beeping and I don’t have throttle, how can I fixed
If I have an ESC with a linear BEC, do I have to connect the BEC, or can I just cover the end of the red wire with some electrical tape? I’m thinking of using the radix PDB, so I don’t need BECs, so is it safe to just not connect them, or would that damage the ESC?
Hello there! I have a small problem that I come down to think it is esc related. I use pixhawk along with hobbypower bl heli 30amp esc with 3208 motors 480kv.
It seems that when I use loiter&alt hold the motors are ”missfiring” if that is the term for inconsistent spinning throttling slightly up and down and unable to maintain stable height.
Am I using wrong firmware for so low kv motors is pixhawk the problem, what can i do?
It’s probably the timing in BLHeli. I played with some low KV motors with BLHeli recently and had to drop it to about 4 or 5 to stop it de-syncing..
If it’s linear then you should be able to connect all the red wires fine. See the other videos in the ‘Introduction to Remote Control’ series on the channel. Best of luck!
+Painless360 Ok I ll give it a try but how do I actually setup the hardware to do the flash?
Do I have to completely remove the esc and find the pads? Can it be done only through the servo cable going to the flight controller somehow? Or can i take advantage of the pixhawk and do it through it?
my motor does it for 3 sec than nothing what can it be?
i have a 2881 kv motor after running for couple hours. suddently it works for 2sec the motor than it doesnt do anything. steering still does it great. i dont know if its the ESC thats failing.
I’d try another ESC but it sounds like a power/overheating issue..
yes but the next day its the same. i put on the battery. give full throttle it works 2sec then nothing. so something is broken. i will buy a new esc then.
Best of luck, if the new ESC doesnt fix it then it’ll be the motor or a dodgy connection..
What if my mother only has 2 cables
Then it’s an OPTO ESC and doesn’t supply the 5v. See my other videos in the ‘Introduction to Remote Control’ to find out more.. Best of luck!
Painless360 thank you
Very very educational. Best ESC explanation. My quadcopter got lost and was found a month later upside down in a puddle of water with battery missing. I cleaned it and dried it out and checked to make sure all the motors still turned freely by hand. After installing a new battery, i tried to fly it and it lifted off and hovered at 4 ft or so as usual but as soon as I tried to move it to the left, it drifted away and wouldn’t come back. I had to run after it to stop it. Could a bad ESC cause this drifting away issue?
If it’s hovering ok then it’s unlikely. See my video on what to check if your Quadcopter drifts.. it may help..
How to make it at home please tell me in your video (yogesh )
Sorry, I don’t understand what you’re asking – check out the playlists on the channel for instructional series on all sorts of models and builds..
Very helpful and very well explained – thank you.
Is there any device or circuit that can be used for the stepper motor that needs more than 5 volts ??…..
can I just connect stepper motor’s + – wire to higher volt battery and just signal wire to receiver ???
appreciated
Not sure on that one. I’ve not use stepper motors with radio controlled devices. The only thing I have used stepper motors in are 3D printers and they usually require some sophisticated drivers to run the Motors. Best of luck!
Painless360 Thanks hi I meant to ask for servo motor instead of stepper …I want to convert toy ride on car to rc controlled and I am thinking to use servo for the steering mechanism
KAVI PATEL I’ve only used servos that are of the same voltage that the radio receiver works on.. Best of luck!
Can I connect the three wires from the motor to the ESC then from the ESC to the battery without the transmitter as I only want it to operate a hairdryer..Thanks
You’ll still need something to tell the ESC how much ‘throttle’ is needed..
i mistakenly connected the middle wire of esc with rigth wire of motor. now the esc is not calibrating it is just beeping
is there any solution for that
Depends on which wire you’re talking about – one of the three that go between the motor and the ESC or one of the three wire cable that has a red/black/white (or brown, orange and red)?
can these only control one motor at a time?
That is a great question. An ESC can only run one motor at time, as it’s actually also sensing the motor position as well as providing the pulses that run the motor. Hope that helps..
okay thanks!
sorry if you could answer another question: i wanted to make a rc car with around 3-4 motors on each side will i just need 8-6 speed controllers
(sorry i know its a dumb question but i’m new to rc)
One ESC per motor. Best of luck!
Hello Sir,
I am very new to Drone Technology.
I just prepared drone with following specifications.
Tarot 650 frame
Pixhawk 2.4.8
Taranisq x7 + X8R
Race star 4 motors
15inch props
22.2 v 4200mah 35C battery.
In today’s first Flight – Drone takeoff successfully but after some heigt it automatically fall down.

ESC – 30A 2S-6S BlHeli Platinum ESC For RC Drone FPV Racing
In online blog some one told me it could be ESC desync problem or May be Mechanical failure.
My request can you help me to identify problem n potential solution for the same.
Thanks

Please see my ‘Quadcopter building for beginners’ series on the channel – they are designed to show the build process i follow that works and avoid common pitfalls. Don’t fly high until you know the model is working well – you’ll just break more stuff. Finally, the crash could be due to many things, bad connection, vibration, settings.. You’ll need to check everything including log files. Best of luck
Mr. Lee you are a RC Guru for many of us……Thank you Sir.!!
So I know of 3-phase motors from commercial A/C work where I swapped electric leads to change the
direction o f spinning but can you likewise change the propeller backwards to essentially do the same
thing or are the propellers notched in a way that they’ll only work in 1 direction? And I imagine some manufacturers can be swapped & others have their own, “Notched Groove” to make sure the propeller
turns the right way? I’m trying to get a basic set of, “Wants/Needs” put together for my flying.
Ultimately I want one Transmitter(easiest/user friendly) & it needs to have several, “Flight Controllers”
it can support/handshake with? Once I can establish this main issue I can have any number of other
components fall into place. My mind is whipping along……
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?
i have a xk a800 plane which has a brushed motor which i want to replace with a brushless. i’m assuming motor speed control is regulated via an analog voltage from the receiver/flight controller, not PWM
(it a simple cheap all in one receiver/controller, not really customizable)
can i simply remove the brushed motor, plug the red and black wire that went to the motor into an ESC for brushless motor? will a cheap ECS accept an analog voltage as control input? thanks
umm i see 666 comments so i made it to 667 comments :and 1800 kv means 18 volts?
does the battery have to be connected to the esc for it to work
Good video! 🙂 Excuse me sir, I have a question, when I make the connection between the motor-esc and try to connect with the Li-Po battery, it makes a cortcircuit I dunno why, so I’ve taken my multimeter and checked continuity in the + – esc wires, and there’s continuity, when it souldn’t be continuity I think, but all this happens whit my 4 pack, I’m getting a little mad, is this normal or I just Lost my money? Thanks and sorry for disturb!
When I connect the battery to my Diatone GT M3 it only makes 3 beeps and not the usual 5 beeps. It won’t arm and won’t connect to Betaflight anymore. I can’t flash the FC firmware. Need help, please. Thanks!
So, I have dual switch 80a Skylord and cuts power to the Rx when any of 12 servo’s are used. Is this because both of the red Rx wire of ESC are plugged in. And at 5v/5a will I need to use another power pack for the 12 sevos. Listed for 6 per ESC. Have not hooked up more than 4 when the power is cut. Edf’s will not cut power. Any help would be great. Thanks Bruce
So the wires of my motors have 2mm male bullet connectors and the wires of my esc’s (the exact same as shown on 19:16) are about double the size in diameter. And have no connectors. Is there any right way I can connect them?
Nice video. Thanks. Btw, you sound like Jack Frags
