Did this video help you?

Lorenzo Van het hul: Is there a way to bypass the esc so i can use it for a selfsustaining turbojet engine project (max speed)? I dont want extra stuff arround in like receiver or servo testen, thanks:)

Chris Kaiser: Do you have any videos on OPTO ESC's with an external BEC and running batteries in series?

rasheed gregory: Im scratch building my first plane and I'm using esc's with a built in sbec what I'd like is how do I find out if the 4 amp sbec will be enough to power 5 tss-11mga servoes?

Neilbrian Bernardino: My rc car is not working because first I try to fix the light of the car and I successfully fix it and next when I open the remote of the car I accident pull the wire of the connected to the batterry actually I pull all the wire and I can't remember if where the two wire connected my rc car is enzo ferrari pls help me ? 

dryan084: New to Lipo's here- so be gentle, How do I know if I have exceeded my BEC budget? How do I know what my "budget" is?

Quinna Pro: Can u help me i got my recevier to talk to me transmitter. And my motor works but my servos won't stop running.. As soone as i plug them in thay run and wount stop or respond to my controls thanks 

League of Rainbows Featuring Draven: Should I have a normal configuration on my RC car WITH a ducted fan and a separate ESC, or should I just have the ducted fan setup. Using this for science fair. Thanks.

James Guile: Hi Bros, does one need a servo? I'm in the middle of building a RC Skate board to mount a camera, it has 2 12v motors which works well with a speed controller but it means long cables, so I want RC. THANK YOU FOR A GREAT TUTORIAL VIDEOS.

James Guile: Thank you for your prompt reply. good luck and take care. 

soundadvice2k: Do you have a video or information for setting up timing for the 2 motors?

Thiago Boccio: Sir, what plugs are that you used to connect ESC to motor??? Does anyone know about that? Thanks for the nice video!!! subscribed.

juan pabon: AWESOME INFORMATION..................THANK U .....JAY...NYC

Solomon Tesfaye: do you have to use a ESC? can you connect the motor directly?

PyroChimp75: Its not mentioned much by most hobbyists but the three wires that power the motor are better known as 'multi-phase' or better known as 'three phase AC, just for those who wish to understand how their motors work, Go look up 'three phase ac electricity on wiki, explains it well about the motor winding in 'star' and 'delta' winding formations :)

Island728: my ESC only has two wires (+ and -) for the motor, if i dont connect the white wire, does the motor still work? please reply thanks

SunTrapped: @2BrothersHobby Thanks for the reply.

2BrothersHobby: @chancho00 - There are some circuit designs you can find on the web regarding homemade servo controllers. Try doing a Google search for "homemade servo controller" and you should get some returns. Keep in mind, an ESC is going to be less forgiving than a servo when it comes to end points and input.

SunTrapped: I want to test the edf fan I purchase is there a way to bypass the electronic speed control so I can test its functions?

colj001: hey thanks for your video but i would like to know how to find the right esc for the motor and battery, if i just pick random ESC's, random motors and random batterys and plug them all together, will it still work or will it smoke and explode. i want to make my own RC plane but these electronics have no indication of whats compatible and what isnt.

2BrothersHobby: If your ESC has an integrated BEC, then no additional BATT connection is required on the receiver. As long as your ESC radio connection is plugged in to the Throttle channel, the receiver should power up and the servos should be functional. If this is the case and your ESC fails to arm, and you are using a Futaba radio system, you'll need to reverse the throttle channel in the radio. Remove the prop first Otherwise, could be an issue with the BEC circuit either not present or malfunctioning.

2BrothersHobby: @gizmoguyar - Great suggestion! I think we'll do just that. There are some tools (calculators) on our website that help with motor selection from a specification perspective, but mounting is another issue. Thanks for the feedback...

planesand carsandtravel: Hi, i have a question, if you have a esc with a bec already in it do you HAVE to solder ANYTHING? Thanks!!

Saad Asghar: Please tell me pleaseeeee that can a rc plane fly without esc ????

moron32: @2BrothersHobby I have one more question, mind if i message you?

moron32: does any of this info apply to rc boats as well? I recently got an older model great planes wildcat ss off craigslist, but the radio system isnt working. I want to upgrade to 2.4ghz, but the problem is the boat currently has a mechanical speed control...i'm thinking i should upgrade to an electronic, but i'm not sure about compatibility with the TX, RX, Servos, and the ESC...i dont want to plug something into something else and blow it!!

mayantribe bx: my esc did not come with connectors where i also have a seperate bec how do i connect them

mark wikstrom: hi there i have a Catalina plane with this system. i have followed all the wiring instructions and everything works OK except the 2 motors. they play a wee tune when you plug the battery in and then a "ding" about every 2 seconds. Should the battery be plugged into the plane with one plug (the t shaped one) AND the other wires. there is currently no plug in the BATT plug on the reciever?

2BrothersHobby: You cannot connect directly to a brushless motor. It actually runs off AC current converted and managed by the ESC. The ESC converts the DC current supplied by the battery to AC, manages the phase, timing, etc. in order to actually run the motor. There's a lot going on inside the ESC. A brushed DC motor however can run directly off a DC battery.

2BrothersHobby: CAUTION!! Sound like you have a brushed ESC, not brushless. In that case, connecting it to a brushless motor will ruin the ESC/motor. Brushed ESCs send DC voltage to the brushed motor. Brushless ESCs actually invert the incoming DC to multi-phase AC. You would be sending DC voltage to an AC motor. Not good. You would most certainly and immediately be letting some extra smoke out of your ESC's electronics and cooking your brushless motor:)

2BrothersHobby: No, the ESC is actually running multi-phase AC current to the brushless motor. Only one ESC per motor.

rip cord: red goes and red and black goes to black is that right? please answer

Jake Woodruff: Well I think this is the perfect place for this. I build robots so I am thinking about adding a weapon. So I was going to purchase parts when I realized the ESC has a continuous current of 6A and my motor has a maximum of 4.1 A so what will happen? Also I have two servos so will an 11.1V battery work? They run up to 9V and my motor runs up to 7V. Thanks

2BrothersHobby: You can use a servo tester to operate an ESC without a receiver or radio system. These are available from a wide range of manufacturers and can be very inexpensive.

mohit chittoria: i have a eagle double horse helicoper consists of a brushed motor,and its battery got damages,i have a lipo 2 cell 7.4V 25c battery can i use it to fly my heli,and my previous battery of heli was a nimh 9.6Vbattery can i replace with my new lipo battery. pease tell me

2BrothersHobby: @Mena142 - Glad it was helpful! We'll be posting several more, including multi-engine, external BEC wiring, and navigational lighting. Check back often or visit our website at 2bfly.com under the workshop section. There are flight calculators and electrical reference information there as well. Let us know if there's something specific you'd like to see....

capt snafu: ive always wondered if you could i use 2 ecs to control 1 brushless motor is that possible

Rūdolfs Kaufmanis: Hi. Im new in to the RC world, and i have a question - is it possible,that i run my rc boat without a ESC?

2BrothersHobby: @moron32 - Yep, the same components are used in boats with lipos and brushless speed controls. In fact, even NiMh and brushed ESCs wire the same way. Connections are all the same with the exception of brushed motors only have two wires to the motor.

2BrothersHobby: @mayantribe - The BEC power is supplied through the single radio connection coming from your ESC (assuming your ESC has an integrated BEC). There are no additional wires for your BEC circuit. Just plug your ESC into your radio receiver with no motor connected and plug your flight battery into your ESC. If the receiver comes on, your ESC has an integrated BEC. If it doesn't, your ESC does NOT have an integrated BEC (or your reveiver connection is reversed, always check polarity).

philip riding: thanks for getting back to me. the you can see the motor i bought from ebay, the item nunmber is 250946319403. i will try a smaller prop. thanks.

xuxixoong: Great video...so much help. This is my second day trying to learn about rc airplanes and you have taught it all in two videos. May I ask where can you buy these materials for a cheap price. I'm a high school student who just loves airplanes and would love to build one with very minimum budget. Thank you

philip riding: I was flying my rc plane with a 2070 rpm brushless motor and a 30amp esc, after 5 minutes of flight i landed it to see if all was ok. the motor was nice and cool but the esc was hot, even though the plane had a good draft of wind passing through the plane. i took off again and tried the plane on full throttle, when i got to around 200ft the motor cut off and i also lost all control of the plane. it crashed. but lucky enough all i broke was the prop, the range on the transmitter is all ok.

MrAlexandros99: can you tell me what is the name of the battery and of the ESC

2BrothersHobby: @TheSliekaStyle - You don't connect your 11.1V lipo to the receiver. You connect it to the ESC. The ESC radio connection back-feeds the correct voltage to the receiver. This is the purpose for having a BEC (battery eliminator circuit) built in to the ESC. It handles the regulation of the incoming voltage down to 4.8 - 6.0 volts for your radio system.

Asadullah21: nice website

2BrothersHobby: Yes, either switch any two of the wires for proper rotation or, if your ESC is capable, change the motor direction in the programming of the ESC. The wires are the easiest way. Some ESC manufacturers offer a plug-in programming card that makes programming really easy as well.

Crispin Andrade: How did you connect your motor and ESC, did you just solder them together or what?

2BrothersHobby: @MrAlexandros99 - The batteries used on this clinic are from Flight Power, distributed by Great Planes here in the US. The ESC is a Castle Creations Thunderbird. This is their value line of ESCs. Very reliable but also very affordable.

2BrothersHobby: There are other replies that address channel reversing as a possible solution (below). If you're not getting any power to the rx and your polarity is correct, than it seems your BEC, at a minimum, is bad. You may still be able to resurrect the ESC by removing the positive radio lead form the ESC radio connector and using another power source (battery or external BEC) to your radio system.

Youtube TV: Is it possible to connect the esc to a motor that have 2 leads instead if 3?
