Nice bench set up, might also mention calibrating the escs all together.... (In something like a twin it's important to be getting relevant thrust from each side.)
I've been looking to make a multi-motor/esc project this has an excellent explanation of the process and options. I haven't been able to find any literature that wasn't 20 years old on this subject , or that didn't give erroneous cautions or methods that just didn't make sense. My local hobby shop actually looked at me funny when I mention what and how I'd like to go about my project, you know like dogs do when they aren't sure what's going on. That was my big sign to find information else where. If you ever do turn this into a document I would gladly store it away with all the other articles and books I have on these subjects
Maybe also worth mentioning that the colors on the 3 motor wires are not relevant - in case people have motors/esc with single colored wires. And maybe also to check the current drawn by multiple motors - make sure the battery can handle it if you use 4/2 motors on a single battery
I'm going to use multicopter escs now. They are smaller and lighter but don't have a bec. For that application i use a multicopter pdb with integrated bec where i can solder on up to 8 escs depending on your board. Now i only have to solder on a single battery connector and that's it 😉
Nicely done , thank you. If you want to power two motors on one bigger battery, do you mean more volts or more amps ? Both ? Can you plug à 6s battery to 2 escs accepting 2-4 s lipo without burning them ?
Great video ! Very helpful. I see that you are using y harnesses to adapt one or two batteries as your power source(s). My question is: Does the use of the y harnesses between the batteries and the esc's require the use of an additional capacitor ? I am currently building an airplane that I would like to install a 6 inch plug in extension between the esc and the battery but don't knowif it's safe to do without adding a capacitor. Thank you for any help.
Good simple description. If multi-motors are connected to separate battery packs, one weak battery pack may result in one ESC going into low voltage cutoff and one motor cutting out. Using a single higher capacity battery pack may have some advantages in smaller models.
Question about a tank setup, lets say i hook up 2 engines on a RC tank platform. each side of the track powered by one engine. Would i then link both engines to throttle at the same time but have them for example like this (ENGINE 1 -> Channel 1 /// ENGINE 2 -> Channel 2. Setup the transmitter for throttle to power Channel 1 and 2 with the same speed. And when i want to steer and use the steering wheel i could then setup my transmitter to infact Slow down 1 of the engines depending on where you want to turn?
Ya you would want to set it up like you said 1 engine per channel. I don't have a transmitter with a steering wheel I only have airplane transmitters but I would set it up as a mix in the transmitter in my case with rudder and throttle but for your case with steering so not actually have servo hooked up for steering but just mix it so has you add steering it slows down eng 1 or eng 2 depending on direction of turn.
Hi, thanks for the video, excellent. I'm busy building my twin electric model. The twin system necessitated (or so I thought) in extending the leads between the battery and the ESC. I'm told this is incorrect and I will be in trouble; the ESC won't work properly, I should installed a capacitor just before each ESC. The leads between the ESC and the motor should have been extended. My leads are ~600mm long. How did you solve this problem on your multiengine planes? Would appreciate a comment.
Since you disconnect BEC Red wire from esc from 2nd & 3rd motor. Can one easily "Reconnect" this red wire back to each connection without need to soldering or needing to buy a replacement ESC?
Is it possible to leave the power wire in the other esc? I'm thinking it be OK since it's in parallel, it would also act as a redundant if the other esc were to fail.
If you are using a dedicated receiver battery that is separate from the flight packs do you disconnect all 4 of the power wires from the ESC’s since the rx is being powered by its own battery?
I really appreciate this video and I tried to recreate the same thing. However I am having trouble only one of the two brushless motors is running. I have 2x40A ESC and 35c/2200mAH battery. Any help would be greatly appreciated
I'm experimenting with a Stock twin prop 550kv set up. 2x 40A esc, 1x 6s lipo and the max Amp draw is 62A. I'm assuming this is over the 2x ESC combined so my ceiling is 80A. However if I'm going to use 2x lipos I'd certainly not use 2x 6s lipos. The power of the 6s is shared with the 2 motors. I feel if I was going to go dual lipo I'd use 2x 4s lipos. (These motors are 4s rated in 4s planes and 6s for 1 motor would surely be into the 90A+). My question is how do I work out the RPM of each motor in my set up? How much voltage do I know each motor is getting on 6s set up? My aim is to change out the motors to 750kv hoping my stock 40A escs are within operating limits. Cheers
I saw all aircraft you build ..im your subscribers from Philippines..im also love doing drone ang aircraft.....i have diy drone but its broke..ang now i want to build aircraft..help mo for needed materials thank .. I hope you read this massage
I'm making my first rc plane project from scratch and this video is just what I needed!
Same for me. I was looking for the two motors.
Same for me. I was looking for the 4 motors for my boeing dreamlifter that I am building from scratch!
Same for me, I have experience flying, but not building. I’m making a twin motor plane with a 70 inch wing span. Almost finished with the wing.
same here
This is very good. You made the topic simple and easy to understand. Thank you
Thank you for this video I can now connect up my Hangar 9 B-25 using two batteries with two ESC’s without worry, excellent video!
Nice bench set up, might also mention calibrating the escs all together.... (In something like a twin it's important to be getting relevant thrust from each side.)
Well done you made a very useful and well done video! Something like this was needed on RUclips🔝🔝
Thank you I appreciate that comment

Good to see you again
Exactly what I was looking for.
Thank you!
So incredibly helpful, thank you!!!
Great video, thank you!
Thanks, glad you liked it!
Great video! quick and easy to undersand. Will you make another one with differential throttle in the future?
Maybe also worth mentioning that the colors on the 3 motor wires are not relevant - in case people have motors/esc with single colored wires.
And maybe also to check the current drawn by multiple motors - make sure the battery can handle it if you use 4/2 motors on a single battery

excellent video thanks, very helpful and to the point with no bs and real world example :)

Thank you. Very helpfull video.
thanks for the video, yes I encountered a problem... one engine starts before the other.
Very interesting, many thanks.
This is really helpful. Thanks for sharing!!
I prefer leaving the ESC plugs intact and remove the power ("+") contact(s) from the Y harness(es).
Great information. Keep up the good work.
Thank you for this!
Awesome video 👍
Thank you 😄

6in extension is definitely ok no capacitor needed.

@TroyMcMillan thanks for rhe reply! I appreciate it.
I was wondering if that's possible, now I know thanks.

Would the main running one for the servos and all, would it go flatter quicker.
Thanks
Is it possible to leave the power wire in the other esc? I'm thinking it be OK since it's in parallel, it would also act as a redundant if the other esc were to fail.
How do you wire it to control power to either side? As in a dual prop boat setup?
Legend
If you are using a dedicated receiver battery that is separate from the flight packs do you disconnect all 4 of the power wires from the ESC’s since the rx is being powered by its own battery?
Yes

What happens if you dont remove the wire in the middle?
Do you have your settings anywhere for the Flsun v400?
Thanks for explanations. Just subbed to your channel..
bro can u give the stimulation for drone
Yo what is the name of that wire harness
:15 four GAS props really?
