I know this is an old video but I learned some new tricks. After 10 or so years, I am now changing from old to new motors & Lipos. Before it was a twin Islander with one controller and old battery. Now I see two controllers and lipo with props running in different directions. Beforev it was also two 05 Cobalts with props in same direction.
Thanks so much brother, you have helped me gain an understanding on how to upgrade the all in one flight controller for my helicoper to something I can bind my spektrum controller with.
Watching this in 2017...Thanks a lot for sharing your knowledge. I'm building a My Twin Dream plane and was wondering how to make the wiring for the two motors... I'm saving this video in my favorites... Thanks again! A million thumbs up 👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍 Greetings from Douglas, Arizona 👍🇵🇷👍🇵🇷👍
Awesome video!! I have been searching all over for an answer and now ive got it. My situation was that I bought a 60 amp esc for my new jet and it doesnt have a BEC built in but I do have an old 30 amp esc that does. What im going to do is wire them like you show except for not hooking the 30 amp one to the motor. That should solve my problem without waiting a month for a bec to get here or adding a heavy battery temporarrily Again thank you!
Nice tutorial! I have plans for an electric twin Cessna 310 and this video verified my plans on setup. Just had to make sure... Thanks for posting. Good Job
To support john50049's point, using one battery for two or more motors does nothing to the voltage, it's just going to consume the battery very quickly. When you wire two identical batteries in series, the voltage is doubled and the capacity stays the same. In parallel, the voltage stays the same but the capacity doubles. Thanks for posting a correct response john50049!
@Zovex11 - Robots, specifically motor actuators, typically rely on independent control so the radio connections would be to two different channels instead of combined into one like we do with multi-engine airplanes.
Thanks so much! I was just trying to figure out how to wire up the P-38 I'm building, and this explained it perfectly for any configuration I want to use with this plane! Thanks!!!
Greetings! Thanks to your videos. It helps. On this particular, you connected individually first each to two batteries. If i only have one battery, can i connect the two esc to one battery directly. Thanks
Yes, on a multi-engine setup you can use a parallel adapter to connect the batteries. Just be sure they are the same size and discharge rating (identical batteries). The clear benefit is that you drain the batteries at the same rate and avoid differential low voltage cutoff which would lead to one motor cutting out sooner than the other. The other leads are the balancing connectors. Balancing chargers use these leads to charge each cell equally for the best performance and pack longevity.
@freak99z - Any manufacturer can be used in a multi-engine setup. Just be sure to verify the BEC compatibility (you may be required to remove one of the ESCs positive from the radio lead).
@boomanfabo31 - Yep. Just get a "Y" harness for the radio leads and it will work just fine. Just be sure the ailerons are moving in the opposite direction before you complete the installation. Since they are both tied to the same channel, they can't be independently reversed, so you're stuck with the physical orientation.
@Teamsorkracing - You would run the two ESCs to two seperate channels on your receiver. As for the operation, that would depend on which channels you choose and how you mix them in the computer radio programming.
Thanks for video Tried doing that on a boat at a boat club meeting and they couldn't figure why it wouldn't work i was using just one battery turns out they told me to remove wrong wire one 2nd esc servo lead which i now know thanks to your video
@boomanfabo31 - The ESCs and Motors used in this clinic are made by E-flite. Just about any ESC and Motor manufacturer support this setup. Just remember to remove one of the positive wires from one ESCs radio connection if you're unsure if they support parallel connections.
@Sunset235 If you are powering your receiver through one or more of your ESC's radio connections, than no. You should be fine. The BEC will provide either 4.8 or 6.0 volts to the radio system (check your specs). The main flight pack voltage (11.1) only gets fed to the motors.
@farcwarts - You're going to have to fabricate or buy "Y" harnesses for both your battery and your radio connections. Drop the positive off of three of the ESC wires and use only one speed control's positive for BEC power.
@farcwarts - Off hand, I can't think of any but some google searches may turn up some options. Problem is: there's no "standard", so the options are nearly endless. If you're comfortable with soldering and shrink-tubing, I'd make your own battery "Y" adapters at just the right length. As for the radio "Y" harnesses, I'd just pick up some shorties and connect them together. That would be easiest.
This config would be ideal for the electric skateboard project, would both motors run at exactly the same speed if they are the same model? I think one on each wheel would make more sense. My other project is to try to charge a large battery or super capacitor bank from several large rc motors, the idea is to create a braking effect on my van so that when i start to brake the motors slow the van and charge the batteries, then whenever i push on the accelerator the motors will aid the engine
@spitfiremk1980 - Not a problem. Just follow the same method: you only need one red wire from one BEC enabled ESC going to the radio system. The others should arm just fine as you plug in your flight batteries. We recommend just pulling the red leads out and taping them instead of cutting them, but that's ok. All you'll need is one.
Yes sir. Look for a pusher prop of the same type, size and manufacture if you're planning on setting up counter-rotating props. You'd need a standard prop (clockwise turning from rear) and a pusher prop for the motor turning counter-clockwise.
This is a great tutorial. I see that others have asked about wiring 4 engines. I want to wire all 4 motors and their 4 individual speed controllers to one lipoly 3 cell battery pack. I am wondering how to configure this. Is there a diagram or tutorial for such a configuration? Particularly confusing is how to bring 4 speed controllers into on Y connector to go to the receiver, and also how to bring 4 motors to one battery connector. Any assistance would be much appreciated.
@airsoftreviewers09 - Yes, on all accounts. Follow the same guidance for 4 engines as we suggest with 2. Just make sure you aren't drawing too much amperage on your radio system for your BEC's rating. In that case, you'd need either an external BEC with higher amperage ratings or you'd need an external battery pack for you Rx.
Is there any chance of having one motor rotating at a different rate than the other, if so how do you advance or reduce that rate so they match? This is important for 2/3/4 motor aircraft too.
Keenan Lee Yes! You accomplish this my mixing in the rudder (usually) you can mix in a percentage of the rudder to each throttle channel to slow down and speed up motors, I start off with 30% +/- To do this you must have a computerized transmitter I use a 9XR. It is easiest to use rudder as you will be simulating the movement of a rudder so it feels natural, you could also use a pot I guess but that would be odd to use.
Garrett Smedley is right. Something to add is to make sure with electrics that you have the inboard motor in a turn slow down, and not have the outboard motor speed up. That way, if you accidently bump the rudder sitting on the ground, the plane doesn't lurch forward and hurt someone.
thank you i am building my first jet with front and rear motors counter rotating. my only worry is using one lipo to power both will eat it quickly so i need to probbably use a bigger lipo now is this correct? means i will have to fly faster to keep the lift great enough to sustain the new weight. i cant wait lol.
Yep, just run each ESC to a separate channel. It doesn't have to be only on the throttle channel, but keep in mind that in order to arm, the channel typically has to be in the "0%" position, so spring loaded centering gimbals will not allow most ESC's to arm. Furthermore, channels that are reversed in relation to 0% and 100% as seen by the ESC will typically put the ESC into stick programming mode upon initialization and won't arm until programming is exited or re-initialized at 0%.
@minileafe - Most ESC manufacturers are ok leaving both BEC wires in place. To be 100% safe, remove one of the RED conductors from one of the ESC radio leads. You can still use your "Y" adapter.
Yep, that's pretty much it but it would have to be on a channel that is in the proper position to arm the motor. If you're wanting to control them both from the throttle channel just set up a custom mix, mixing the second motors channel with the throttle channel and you can sub-trim, set throttle curves, etc. if you're looking to sync the motors.
pertty nice, also what could be added as benefit of parallel BEC in addition of redundancy, is that you get twice much power : so 2 BEC capped at 2 Amps become stronger BEC at 4 Amp, even if i am aware that your plane will not need it
@eventhorizonbm - You're absolutely correct. You'd need a standard prop(clockwise turning from rear) and a pusher prop for the motor turning counter-clockwise.
@homebrewman23 - I would suggest disconnecting the white wire from the ESC you're using as a stand alone BEC. That way no errant signalling is sent to the second ESC. I've had some strange arming attempts happen before with ESCs that were only being supplied 5.0 volts from a radio pack during setup. Just to be safe and ensure no mid-air issues..:)
if i wanted independant control of the motors how would i do that? i dont supose it would be as simple as removing the Y adapter from the receiver and plugging into 2 channels?
@snakev10v5 - Yep, just multiply everything by 2, and use Y-adapters to get the radio connections linked. Alternately, if you have a computer radio system you could "Y" two to the throttle channel and the other two to an AUX channel and mix the channels together.
You'd need a monster switch due to the current loads. We use an arming switch on bigger models that works great. It uses an Anderson Power Pole plug so all you do is unplug the cap when you're done flying, plug it in when you're ready to go. It's made by Maxx Products. I can't link in comments but go to maxxprod dot comm, click on accessories, and then page 2 of 4 in the top navigation. Scroll down and you'll see the different size arming switches depending on the amp rating of your setup.
This has been discussed a lot over the years. Probably the best bet if you don't want to set a throttle curve on one using two channels is to get ESCs that have governors. You could get into the ESC and adjust the governors to a specific RPM. No external sync's that I'm aware of for electric, only fuel.
hello...nice explanation, good job...i have a question, i need to connect 4 esc in 2 batteries, 2 esc in each batt, and one receiver...how i can do that
Hello. Very informative video. I am experimenting on bypassing the joystick on a wheelchair and it appears that this system is inline with what I might need to control the chair without the need for the joystick mounted on the chair. I imagine that this system will not produce the power needed to pilot the chair, but my question is if you have any suggestions as to a system that might.
Thanks for the response. Does anyone sell a 4 Y connector or do I need to take two Y connectors and splice them in order to get 4 leads to go into one input for the throttle and the battery pack? I can make one if I have to but wonder if someone has already done so commercially.
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?
Either isolated or parallel are acceptable configurations. For people who cannot parallel the main packs, don't be concerned. This is perfectly acceptable as well but you're best to manage your flight times and land before cutoff, just to be safe. The Hangar 9 Twin Otter comes to mind. You physically cannot parallel the batteries since they reside in each engine nacelle. This is still an acceptable practice, but calls for flight time management.
@veilkrand - Yes, with twin engines you typically buy one standard and one pusher prop and run the pusher prop motor (typically the right motor) counter-clockwise.
CAN YOU RECOMMEND ANY GOOD REFERENCE BOOKS, THAT HAVE GOOD INFORMATION, ON DESIGNING/ASSEMBLING/COMPILING "MULTI-MOTOR" ELECTRIC AIRPLANE SYSTEMS??!!!...
iv got a 4 in1 reciver that come with my doubble horse 9053 heli. i want to change the reciver becasue this one range is crap. problem is i dont no if a normal rc reciver will work.because the right stick on the controller left/right controls the spead of each motor. and the left control stick controld moth motors speed at same time.
After spending ages on other tutorials this one was the best.
Perfect video thankyou.
This video may actually save my sanity. So clear and straight forward.
It does remind me of "Thing" from the Adams Family.
THANK YOU, FOR THIS, EXCELLENT TUTORIAL, ON THIS ASPECT OF MOTOR/BATTERY/ESC/RECEIVER CONNECTIONS!! AWESOME!!!!! MUCH APPRECIATED!!
This has to be one of the best explanation out there on how to do this, thanks a lot for posting :-)

This is very useful thanks I'm buying a twin engine FPV, and I had no idea how to reverse one of the motors, now I know. really cool!
You vids on wiring are very good.
Very good video, tells what u need know i very good way. Thanks for making this 😃

how did it go? ik I'm 13 years late lol, but still
It looks like "Thing" from the Adams Family has found true love.
Great video!
Great video with great info. Thanks for making it!!!
Greetings! Thanks to your videos. It helps. On this particular, you connected individually first each to two batteries. If i only have one battery, can i connect the two esc to one battery directly. Thanks
Excellent video, thanks for the info
2020 and this is still a great video
Thanks for the video! It explained everything I needed to know.
Thanks this helped a lot for planing my twin EDF YB-70 Valkyrie
Thanks, this will come in very handy on my 1/5th scale Mosquito.
That was a fantastic and very helpful video thanks. Love those quick informative video that don't waste time. Many Thanks
Brill post. Very informative 👌👌👌👌

just perfect for my battleship thanks alot mate 👍👍👍👍
Outstanding video! Brilliant newbie information.
Do you need to use two batteries? Can they be wires to the same one?
Thank u for ur explanation....I was really worried for how to connect the motor for my psv scale model ship
Great video,thanks so much
This helped me so so much thank you!!! I will now Hook up 10 ecs for no reason other then I can lol
You guys are amazing thx so much for all your tips.

Thank you for the tutorial on multi engine esc wiring, and one queation is why is one esc unplugged from the connection pin??
Thanks for the video, just confirmed this working on my vehicle. Hello dual rc550s :P
@snehalmachan - The ESC used in the video is an e-Flite Pro25 Amp
@Teamsorkracing - You would run the two ESCs to two seperate channels on your receiver. As for the operation, that would depend on which channels you choose and how you mix them in the computer radio programming.
Thanks so much for making this video, answered alot of questions for me with multi motor setup, Currently making a 8 foot wingspan flying wing :D
Thanks for video
Tried doing that on a boat at a boat club meeting and they couldn't figure why it wouldn't work i was using just one battery turns out they told me to remove wrong wire one 2nd esc servo lead which i now know thanks to your video
@The787guy - This demo used e-flite ESCs (pro 25's) and e-flite motors (Park 450). Yes, it supports parallel connections.
@boomanfabo31 - The ESCs and Motors used in this clinic are made by E-flite. Just about any ESC and Motor manufacturer support this setup. Just remember to remove one of the positive wires from one ESCs radio connection if you're unsure if they support parallel connections.
that first sound that the motor makes... thats all my motor makes it does not make a connection sound after that... what should i do?
GRATE, I finally know how to do it properly!
@Sunset235 If you are powering your receiver through one or more of your ESC's radio connections, than no. You should be fine. The BEC will provide either 4.8 or 6.0 volts to the radio system (check your specs). The main flight pack voltage (11.1) only gets fed to the motors.

great vid,please can you tell me how to connect three brushless motor to reciever?please reply
you could also use a simple v-tail mixer to have yaw capabilities through the rudder channel
thanks i found it very easy.
Would it be possible to wire in an on/off switch so you could plug both batteries in then just flip the switch to power the system on or off?
right side prop is onbackwards.
but thanks for the info you helped me alot
@homebrewman23 - I would suggest disconnecting the white wire from the ESC you're using as a stand alone BEC. That way no errant signalling is sent to the second ESC. I've had some strange arming attempts happen before with ESCs that were only being supplied 5.0 volts from a radio pack during setup. Just to be safe and ensure no mid-air issues..:)
do I have to take out the positive wire from the ESC? Or does it work with leaving it?
THX
Q. can a servo Y harness be used for a Esc to plug to of them into a reciver?
if i wanted independant control of the motors how would i do that? i dont supose it would be as simple as removing the Y adapter from the receiver and plugging into 2 channels?
i want to use 3 esc.. do i just disconnect 2 of the esc's bec wire and leave one bec wire on the other one ? cheers for any replys :)
@snakev10v5 - Yep, just multiply everything by 2, and use Y-adapters to get the radio connections linked. Alternately, if you have a computer radio system you could "Y" two to the throttle channel and the other two to an AUX channel and mix the channels together.
You'd need a monster switch due to the current loads. We use an arming switch on bigger models that works great.

Is there a way to wire it such that each motor can be controlled independently?
This has been discussed a lot over the years. Probably the best bet if you don't want to set a throttle curve on one using two channels is to get ESCs that have governors.

Thanks for the response. Does anyone sell a 4 Y connector or do I need to take two Y connectors and splice them in order to get 4 leads to go into one input for the throttle and the battery pack? I can make one if I have to but wonder if someone has already done so commercially.

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?
can this setup be done with one esc rated to run two brushless motors???
Awesome tutorial clear video.....explained perfectly nonsense very concise......can you do one for a twin rc boat with esc that have reverse lol
Either isolated or parallel are acceptable configurations. For people who cannot parallel the main packs, don't be concerned. This is perfectly acceptable as well but you're best to manage your flight times and land before cutoff, just to be safe. The Hangar 9 Twin Otter comes to mind. You physically cannot parallel the batteries since they reside in each engine nacelle. This is still an acceptable practice, but calls for flight time management.
@veilkrand - Yes, with twin engines you typically buy one standard and one pusher prop and run the pusher prop motor (typically the right motor) counter-clockwise.
Very helpful thanks 😊
