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
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
mayantribe: 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
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....
SergioGinoCharles: for the items
capt snafu: ive always wondered if you could i use 2 ecs to control 1 brushless motor
is that possible
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
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
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
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?
gary wilson: i have a grayson hobby 50 amp esc,when i plug the battery in,nothing not
even a beep it want even light my receiver, bad esc?
102Traveller: I believe thats because of an incorrect throttle signal, the same thing
happened to me with no throttle signal on the ESC. But 2BrothersHobby would
know for sure.
gizmoguyar: @2BrothersHobby Of course. I'm always thankful of people like you who help
us beginners out.
amirnasher: Good vid, thank you. now I know more :)
Muhammad Sohail: I really like this helpful video.
chancho00: How to operate a motor brushless with the ESC but without using a recector
and transmitter, what kind of signal is needed at the orange cable? Can I
put a potentiometer to the positive and the orange cable to simulate the
mark hall: Good video
wallaguest1: why reserver just the outer wires? if you can mix them the way you want all
you need to reverse the rotation is reverse two wires, no matter wich ones
are, i am wrong?
Mecopteran: I am looking into buying a brushless motor for my Exceed Champion, and the
only information on current is the max efficiency current, which is 48a.
what should the amps rating on the ESC be?
