video still helping people 10 years later, nice👍
Wow this was soooo helpful. I have an old redcat wendigo RC car laying around. The car its self is built poorly and parts on the drivetrain keep breaking. However, the electronics are still good, so I was thinking of buying another motor and esc and converting my longboard to an eskate since I also have some spare eskate stuff. I wasn’t sure it was possible but now it seems like it may work
Thanks mate for your help I ilke to connect 2 160A ESC with 8S battery for 1/5 scale RC car
Thanks for making this. Im about to do a dual brushless motor/ESC Emaxx and you've answered the questions i had, thanks!
Glad I could help out! www.Rc-Help.com
Thanks! Came in handy since I'm wiring to ezrun max6 to a single receiver on a dual motor mountain board. Appreciate.
Thank you i got an old alfa models Beaufighter and was wondering how i was going to go about it and i am going with one battery too thanks to you have a great day and thank you for sharing your knowledge
So does it mean that the ESC where the red wire was disconnected will only power the 1st motor whereas the other ESC will power the 2nd motor,receiver and any servos connected to the receiver?
Just so helpful
Glad it helped
Thx
Can someone tell me where to get ehe specific y adapter please and thanks ..yes 10 years later this video is helping ..just got into the hobby ..so im learning very very fast
that was a great video thanks brother.
Glad you enjoyed it! www.Rc-Help.com
Great information and explaniation thanks for doing this vid .my project is a factory dual.lead 775 traxxas can.truck.motor and truck escs or 2 60 amp likw ones you used work ?and run that big brushed motor on 2 big 2s 5000 mah lipos .on a 1/10 traxxas tmax E conversions.
Thanks very very very very very much for this video now I can buy a fpv drone frame and the brushless motors and rig the two motors and esc together and then do the same thing as the other motor and esc
I definitely do not know your setup, however on a quad the motors are wired individually and have their own ESC. The power wires can be soldered together as can the small servo wires, but the signal wire will need it's own signal so that motor knows what to do in the air. Again, I don't know your setup, just pointing some things out for those that may read the comment. www.Rc-Help.com
@@RcHelpDotCom what do you mean the motor wires have their own ESC individually and I don't think drones have a servo as far as I know the fpv drones I don't think they do do you know if fpv drones have servos and what do you mean about the signal wire where is it coming from and where does it plug into
@Dustin p Lee On a quad, the motors will have their own ESC per motor. In most cases these days, all 4 (or however many motors you have) will be on a single board under your stack. Unless you are talking about a plane with dual motors, in which case, I do apologize. I was referring to a quadcopter. Apologies for the double ping by replying with my other account previously if you received an email on that one as well.
@@RcHelpDotCom yes I'm talking about a drone I was not going to use a stack of its possible i was just going to do the wire harness and soldier the esc together or can I connect to the esc together and does a drone have servos and how do I solider to use 1 battery and do I solder the battery to the one of the ESC or the connector to the ESC and I was going to just use a receiver and transmitter and where else can I plug the other wire harness for the other two esc's and Motors into what port on the receiver and how do I solder the ESC together and can I still plug the connector in one of the ESC after it's been soldered together and can I use any motor and with the different ESC
Hi, 1Q. for EDF motor what BRAKE TYPE should choose. Normal / Proportional ? and what is the advantage? 2Q. CUT OF VOLTAGE which is good for Lipo cells 3.0v / 3.2v / 3.4v / 3.6 v ? 3Q. start up mode Normal / Soft / Very soft which one to choose and why we choose 4Q. Timing 0/5/8/12/15/20/25/30 seconds which one to choose and advantage ? Thanks.
1. using brakes on an EDF has no real affects to how it works. On a glider, you would want brakes on so the prop would stop and fold. With an EDF, I always just left the ESC stock.
2. I set mine at 3.2. If you are seeing it hit the LVC too soon though from too much amp draw (voltage sag), first I would look at getting better batteries, but you could also try lowering it to 3.0 or 3.1. But you are risking damaging the cells going that low.
3. Startup for an EDF or prop plane should always be normal (linear to stick movement). Soft start settings are for helicopters so the tail doesn't whip around, and also looks pretty cool lol.
4. Timing is going to depend on what the motor manufacturer suggests. Some motors like a lot of timing advance and some don't like much at all. I would look up the spec sheet for your motor and see what it says.
Hope this helps. www.Rc-Help.com
Hi Tonny, thanks for your quick reply. I am using Freewing EDF Motor. (2836-3300kV Brushless Outrunner Motor - MO028363)
Motor Type: Outrunner
kV Rating (RPM/Volt): 3300kV
Maximum Watts: 520W
Continuous Current: 35A
Maximum Burst Current: 41A, 10 seconds
Recommended Battery (Input Voltage): 4S (14.8V)
Recommended ESC: 40A
Recommended Propeller / EDF: 64mm 12B plastic fan
Slots, Poles: 9, 6
I can't find any specs on that motor of where to start, so I would start with a lower timing number, fly it, and see what the temp of the motor is. Keep doing this until you start to get a hot motor after flying, then back it down one notch. Don't jump way ahead, it can severely over heat the motor. Of course you do this at your own risk since there is a chance you can burn up the motor. But start low and work your way up. Flying time should be about two minutes of normal flying. That should be more than enough to get some heat in the motor. www.Rc-Help.com
I am planning on building an electric skateboard. It will need two of these "vesc" esc controllers one for each rear wheel. Now the vesc controllers are software configurable so not exactly sure how this is going to work. You do get dual vesc units but they are way more expensive.
Why do you need to disconnect one of the red wires?
Awesome thanks
Question, say for example I wire both my ESCs through the y harness and I lift the red wire out of one of them. If i chose to switch off the master esc (the one that still has it's red wire) what will happen to the slave? (the esc that doesn't have it's red wire) Will the slave work perfectly on it's own?
I imagine you have already figured out the answer to this but...
Switching off the primary will switch off the receiver which could result in a run away 😅
@@ManuelOrtizification yeah
@@Lunarpollo5622 im now trying to figure out if i can run both ESCs on the same power switch 😅
well executed tutorial, sir.
Very helpfull, thanks! ✈️
11 years later
It really helped me thanks men
Can you tell me why you're removing the + line on one side?
If you use both, you can multiply more stable power supply, so I wonder why.
Thank you for a very informative video, greatly appreciated and keep it up.
What if both ESC’s have a BEC? Many of my ESCs have a BEC which runs on a seperate 3 wired plug. How do you manage that being that BEC plugs into reciever for power also. ???
It's important to use the same Guage wire for Y harness as the batt wires.
The POWER adapter, yeah. For the signal wire Y, what the video calls the Y-adapter, that only carries a DSHOT digital signal and should be a fine-gauge wire.
i have a dual motor rc with 1 esc how would i hook up one motor instead of both using esc
I have the same situation. I want to connect two sscs to one receiver. But how dose the receiver without the positive work? Can you please tell me. Thank you
Can this apply to a tank?I'm new in RC
thanks for the video! I have a question for you... I want to run 4 brushless motors (for a car, one to each wheel) How could this be done so that the motors are all spinning at the same RPM, start stop at the same time... etc? Is there a way to do it with less than 4 ESC's?
Thanks in advance for your time!
Very cool! thanks for the input. I'm wanting to do a weird custom build thing. Motor to each wheel. Might be awesome... might be garbage.. won't know till I try, right? hahaha thanks again!
ok, cool. I will post some progress when i get started. doing my research now... trying to figure out all the angles before i start spending that $$$ :)
I guess it didnt work
I have a 4 channel radio & I need to plug in a single yellow signal wire for a ESS Dual Sound Simulator into my receiver but I have no channels left. Can I tap into a white servo wire?
In looking at that speaker, the yellow wire should (I believe) run off the signal wire from your ESC. So I do believe you can Y off that wire. But definitely check with the manual of the one you have since there are variations of this speaker.
@@RcHelpDotCom Thank for the reply. I was able to tap into the sevro signal wire & connect it.
Can you show and explain about two esc plug in throttle and gear rx mixed both with rudder and mixing setup? Thanks...
Nice work Tony.....
Hi. Thanks for sharing this. I am planning to build a dual motor rc boat. But i have a lot of questions, can this be applied to a normal 2.4ghz controller with the steering wheel thing? If i try to turn will one of the motors automatically slow down? Thank for answering.
This would be better done with mixing. I would setup the servo for the steering, and do a mix for the motors to adjust the thrust of each motor. This will require a computer Tx though. www.Rc-Help.com
Amazing thanks for that ive done what u show but both escs are beeping lots?? Any ideas thanks 👍👍
Not enough information. Look in your user manual for your ESC's and see if it has a beeping code that you can decipher.
This is very helpfull for me as i am brand spankin new to building rc's also understanding electronics too . I am going to do a bruder cat road roller, and want to run one battery for two esc's to each motor, So thank you for posting this video. I do however have one question. Why do you need to remove the one positive wire from the one esc? In my mind i thought just plug the wye harness into both esc leads to the receiver and away you go. Clearly this is not the case. I could just copy what you are doing but it is good to understand why you are doing it. Could you help me to understand? thank you again :)
If your ESC(s) have switching BEC's, you want to remove one wire (red) since they can backfeed voltage into the other ESC. It will also cause the voltage going into the Rx to be inconsistent which in most cases is not an issue but with some it makes them mad lol. I just find it safer to take out one red wire. www.Rc-Help.com
@@RcHelpDotCom thank you very much
@@rcconstructionincanada3754 No problem.
If you are dealing with very high voltage coming from one battery and going into two escs that go into two motors and one receiver can this method work to control both motors?
Can I connect 2 motors in series, for example I have 6s battery and 2 3s motors, so I want series connection to divide voltage by 2 for each motor ?
will the motor 1 run at lower speed and motor run at higher speed if i wanted to?
no. you can't
Thanks
Are you using a PUSHER prop on the motor with the SWAPPED ESC wire?
Need help in rc boat Electronics,pt109,duel props,2 batteries,do I need 2 ESCs,or,2 motors?
can I just strip all the wires on plug that goes into the reciever. if I do that on both escs could I then just solder each red, black, and white one together?
Hi Tony, what is the purpose of unplugging this red wire? ie: what is the problem if it isn't unplugged?
Mike Lomas I'm guessing bit would be too much power going to the receiver since it already has power from one battery.
The reason one of the red wires is disconnected is to prevent backfeeding BEC power to one of the ESCs. The ESCs will say 5V-ish for BEC power. Even if the ESCs are the same make and model, the BEC power supplies will not be exactly the same voltage. Since the power is directly tied together from both ESCs via the Y-Splitter the BEC with the higher output voltage will be backfeeding power into the ESCs BEC power supply. This can cause various problems depending on the design of the ESC electronics. You could also wire diodes into the circuit. There are benefits to using diodes, it is more complicated and not technically necessary.
Is it the same methods if you use 4 motors and 4 esc?
What is a method of 4 ESC connect parallel on single pixhawk pot
What is the name of the extension cable ( harness) you used in this video?
could you use differential thrust like that though?
When connecting the batteries, do you have to plug the powered ESC first and then the non powered ESC ?? Do you disconnect in the reverse order ??
Thx
both escs are powered, he cut one of the 2 becs which gives power to receiver, without explaining it
Wouldn’t the thrust (thus the pull) be more on one side, by doing this method?
Not if you calibrate both ESC's together to the throttle. Then, they will be equal. However, you could plug them into different ports of the receiver and add some mixing for differential thrust... www.Rc-Help.com
Can you make a video like this about 4 motors and one harness wire to connect in the receiver. I want to basically get all 4 of the motors running with one wire and one esc. I’ll subscribe to your channel and wait for the video thanks.
I just have one question for you sir.....
HOW MANY HANDS DO YOU NORMALLY HAVE???🤔🤔🤔
Got a puzzle / problem I need some help with: I have an RC car with two different ESC's, one for the main motor and one that I'm planning to use to power lights. However, the built-in BEC's output different voltages (the one for the motor 6V, the small one for the lights 5V). To connect both ESC's to the receiver, I'm removing the positive lead from the small 5V BEC ESC. The problem is now that when I connect both ESC's to the same battery for power, there's lots of current flowing through the ground wires as if it's a short for some reason. This does not happen if I either use two different batteries for the two ESC's, or if I don't connect the ground wire from the small ESC to the receiver.
The trick is, I don't have any more room for more batteries and I must connect the ground wire to the receiver in order for the small ESC to properly take the signal.
What the hell do I do??
The ground wire that connects to the battery and the ground wire that connects to the receiver should be connected. A common ground is what I always try to shoot for so I know everything is talking on the same field. If you are getting a large drain with both ESC's connected to the same battery, or both ESC's connected to the Rx, then something (in my opinion) is wrong. If you have the red wire pulled from the smaller ESC, it should have no way of passing current unless it is not seeing a low throttle signal and is trying to drive something out of the main leads. This one is a head scratcher. Come over to the forum and post up some detailed pictures of what you are working on. www.Rc-Help.com
@@RcHelpDotCom I did some digging and I found out that my main ESC is a bit weird. It's a Traxxas EVX-2, it has two connectors for batteries but it seems to run them in series and not in parallel. The BEC of that ESC is only powered by one of the two batteries however. That means the common ground is either connected to the ground of one of the batteries if I connect the small ESC to the battery that powers the BEC in the big ESC, but it is connected to the positive of the second battery if I let the small ESC draw power from the second battery. It seems I have connected it to the battery that doesn't power the BEC in the main ESC. I'll replace the burned wires today and see if it works...
Dude, thanks so much for that reply. Can you post a model number for that ESC? This is the first time I have heard about an ESC that has dual battery connectors that are wired in series. I would really like to dive farther into the schematics and what is going on with that ESC. Thanks again for the reply! www.Rc-Help.com
@@RcHelpDotCom No problem! I love the learning process, too. However, I bought the truck used, it's a Traxxas Summit. The previous owner told me that it's an after market ESC because the original one didn't have a LiPo cut-off built in, this one does. I only know it's a waterproof Traxxas EVX-2 for brushed motors. If you search the name you'll find some wiring schematics and the manual.
BTW I replaced the wires and it's exactly as I expected: It works fine as long as I power the smaller ESC from the battery that already powers the BEC inside of the main ESC. Kinda inefficient setup but it gets the job done until my brushless ESC arrives in the mail :)
@@RcHelpDotCom Oh and about the model number, From the pictures I believe it's thisone: traxxas #: 3019R
Hey! I'm planning to power my two engines just like you showed using a 6s 8000mAh battery but I wanted to power my flight controls using a small 4s, probably 4800mAh lipo... would that be possible? If yes can you tell me how to do it? Thanks
It is possible. In that case, you would remove the red wire from BOTH ESC's and you would run a separate BEC to power the receiver and servos. This way, if you have a motor or ESC failure, something burns up or whatever, you still have a secondary power source (actually I guess in this case it would be primary lol) that keeps your servos and receiver working so you can dead sick the plane back to the ground. Just be sure to remove both red wires from the ESC's so that you are not feeding voltage in from them AND the BEC. Castle makes a really good 10a BEC. www.Rc-Help.com
Thanks it was helpful
Glad I could help out.
Not sure if anyone has already asked this but would you be able to do a video on how to do 4 motors if the same type as in this video
If you are using a single battery, it would be the same as here. If you are going to use differential thrust or multiple batteries, there is a little more setup. How are you going to set it up and I can try to help out. Posting up on the forum may get a faster response if you are in a hurry. I apologize for the two day delay, had some computer issues out on the road. Hope to see you on the forum. www.Rc-Help.com
Hi Dave I was hoping that you can suggests a combo that would work for me I fried my dual vxl project and dont know which ESC can handle the set up.
Your best bet on this question is to come over and post up on the forum. Let us know what motors you are running as well as what batteries and we can help you out. And I'm not sure who Dave is... www.Rc-Help.com
Hello sir is this applicable also in brushed esc?2 brushed esc 2 brushed motors and 1 battery and 1 reciever?
Yes, same principle. Just be mindful of the battery rating as it will have double the amps pulled from it. Also, be sure to remove one red wire from the servo plug on one ESC. www.Rc-Help.com
@@RcHelpDotCom thank you do much sir.
@@RcHelpDotCom Thank you sir for your reply.so much better I have to separate a battery on each ESC?
You can run the same battery, just be sure the battery will handle the power draw. Apologies for the delay in responding, youtube automatically adds a filter and I don't see replies without removing that filter.
So for 1 battery I just stick my positive in positive and negative in negative?
That is correct, you will just wire the two ESC's in parallel to the battery.
RcHelpDotCom ok, will I have to strip the connectors to do so?
You can actually just purchase cheap parallel battery adapters pre made. Just get it for the connector you are using. www.Rc-Help.com
love it thanks
Glad you like it! www.Rc-Help.com
Excellent! I tried NOT doing this. That was bad.
I'm glad I could help out! www.Rc-Help.com
is it possible to plug each esc into there own channel to give it independent controls? built me a lowrider but now I want to hook up a brushed motor to get hoping capabilities. I have one esc to move car fwd/Rev
RcHelpDotCom ok..I already got r servos on there. is it a better to run another battery for second esc? I have a 3s lipo on my 1st esc to power it up. debating to add a battery to power up receiver
RcHelpDotCom ok. so I wouldn't need to have a battery going to 2nd esc? if I do I need to remove red wire. is it possible for me to email you. I'll send u what my setup looks
Thanks for the video, I just cant figure out why one of my counter rotating props in my twin is in reverse. thanks in advance.
If you have brushless motors, just reverse any two wires going to the motor to reverse it. www.Rc-Help.com
RcHelpDotCom thanks for taking the time to respond. When I match up the ESC colors with the motor, they both spin CW, but when I swap two of the three wires on one side, It pushes that motor backwards (reverse) and CCW. So now I have CCW with one motor going forward when the other going reverse.
Isn't that what you want?
@@adventurwithken412 You need a different proppelor if you want one to be CW and the other CCW but still thrust forward.
would this work with 1 motor 2 esc for a 32s configuration
I have one bldc... i try direct connect with my battery.. but couldnt cos bldc have three wire and all batery have only two output i.e. +ve and -ve.. so i just keep inside my box now... looking every youtube video for help but couldnt find till now.... so sad.... i am sad.. my bldc couldnt run..
Bldc needs ESC to work.
do i still need to remove a wire if im using a separate ubec and 2 esc,s that has no becs?
thanks mate you helped a bunch!!!
Can a single 30a esc b used with 2 1000kv motors and how much voltage this esc needs to run one r two motors
I have no idea, KV is ONLY RPM Per VOLT. It tells me nothing about voltage handling, amperage handling or wattage. It ONLY tells me how fast the motor will spin with a given voltage.
So how much voltage should b given for 30 esc?
I have no idea. You gave me an ESC rating and what the motor rpm is per volt.
Thx for this and would it work for a twin brushless RC boat
It should work just fine for a twin brushless boat. Just make sure you have enough battery to handle both motors and ESC's. www.Rc-Help.com
RcHelpDotCom is 2000 mah enough?
I would have absolutely no idea if that is enough or not. You would have to calculate your motor draw x2 since you are running two of them, and compare that number against your batteries C rating for discharge. Check out this video for more information on how to do that. czcams.com/video/LlSa2f76QiU/video.html
Where can I find a two female one male y harness two connect my two ESC to one Lopo battery?
If you cannot or do not want to make it, the next best option would be to buy it somewhere like Banggood or HobbyKing. Just double check the solder joints as I have found them to be cold joints from time to time. www.Rc-Help.com
@@RcHelpDotCom thanks you so much for the reply. Quick question, what are soldier and cold joints?
@@anthonyfakhoury7427 Cold solder joints are joints that were not properly heated and tinned. If you drop a piece of molten solder onto a table, you can just pick it up (after it cools off). This is a cold joint because the metal table was not properly heated. The same can go for terminal ends where you can solder wires onto. If it's not properly heated and tinned, the solder will not stick. Usually a simple tug on the wires is all that is needed to test the joint (there are definitely exceptions).
Want to say thanks, sent a people people your way.
I did this. But one of the 2 motor's is starting late. Any suggestions??
You will need to calibrate your ESC's to the Tx. Just raise the throttle on the TX (with it on of course), plug in the ESC's (without props or blades on) and wait for the two or so beeps, then lower the throttle all the way down. Once you do that, both motors should start at the same time. www.Rc-Help.com
RcHelpDotCom It worked! Thank you soo much!
Glad you got it going and happy I could help! www.Rc-Help.com
Now how would I know if the battery can handle the 2 engines?
Go by the motor recommendation.
Use wire nuts.
this works the same for rc cars?
Yes it works for rc cars
where can i get the y harness
Amazon
how to spell y hounus???
Y harness
Use a vtail mixer
thank bro I almost throw away my two ESC from Freewing
but why cut the red wire....
cut the red wire so you only have 1 ground wire
I believe the red wire is a power wire. The purpose in removing it is because you can't have 2 power signals coming into the Y connector from your ESC's.
@@MrBucknasty1313 im glad i read your comment because this is my next project. Thanks dude!
Tell me the battery details that you used bro
I think for this particular setup I was using this on a duel EDF setup. The battery would have been a 2200mah 3s 45c pack. It came down warm and needed to be a higher C rating, but did not puff the pack. Just make sure your battery can handle BOTH motors. www.Rc-Help.com
RcHelpDotCom how much "c" can 30amp esc handle. if two motors are used.
A 30 amp ESC can handle 30 amps as stated. The C rating is for the battery and it the discharge rating. Sometimes it is also the charge rating, but charging should always be done at a 1c or 2c for max pack life. To understand all of this, check out this video. czcams.com/video/LlSa2f76QiU/video.html
I do big poo poo
very bad
Is I use one battery will it give me the same amount of Volts with half the amps or the same amount of amps with half the volts?
One battery will provide however many amps and volts that the battery can provide. You just need to calculate how much power the motors are requiring and make sure the battery can handle the draw.
