How to Connecting ESC to Receiver

How to Connect ESC to Receiver: Explained in Only 2 Steps!


As a beginner, it can be quite overwhelming for you to connect different electronic components. Especially the ESC wiring. But we think we can make things easier for you.

So are you eager to learn how to connect ESC to receiver?

It’s fairly simple. On the receiver, channel 2 is going to be your ESC wire. The wires are going to be red, white, and black. So you put that in channel 2. Once everything’s set, go in and plug your battery. Turn on your remote and your car. There’s gonna be a beep. And your brushless Rc motor will be ready to function.

This pretty much sums up the task. But you’ll have a proper understanding of it once you read the whole writing. 

So sit back and read along-

What Are The Components of ESC?

Before beginning the process, there are few things we want you to know. 

ESCs can appear in different structures and lengths. From very small ultra-micro 7amps or less to 60amps plus. One thing you’ll find very common between all of them. They have the same inboard and outboard connectors for primary connection. 

Some ESCs have supplementary data recording capacities, you can engage them with portable appliances. Finally, they keep three cords that attach to the brushless motor. They retain 2 cords that apparently attach to your flight battery. Also, they have a radio system connection. 

Most ESCs have BECs. BEC implies Battery Eliminator Circuit. It takes out energy from your central flight battery. Backfeeds it through the transmission coming from the ESC into your receiver. 

Authorizes all your servos and different electrical appliances you have to operate the aircraft. There are amp constraints to a BEC built into electric speed control. So always review your allowance. As we cite it as an electrical word, review your necessary budget. Ensure that you’re not outperforming the capacities of the BEC house to your ESC. 

You can consider an ESC as an independent component as well. It combines into the throttle receiver power channel. Or joins into the receiver itself. You can observe this extensively in Rc toy autos.

How to Connect ESC to Receiver?

A quality Rc receiver has four channels labeled as channel one or CH one. Channel two as CH two and channel three as CH 3. It also says VCC binds that obviously, your buying channels in red letters. Then it has a red ‘S’, a plus sign, and a minus sign and that’s just basically for accessories. 

Now let’s learn the steps-

Step 1: Wiring ESC to Receiver 

First, you want to make sure your vehicle is off. Just in case unplug your battery. On the receiver, channel 2 is going to be your ESC wire. The wire is going to be brown being the negative, red being the positive. And the orange is the signal. So you put that in channel 2. 

Step 2: Plug-In The Battery

Once that everything’s set you go in and plug your battery. Turn on your remote and turn on the car. There’s gonna be a beep. And your brushless Rc motor will be ready to operate.

Hopefully, you’ve connected your ESC to the receiver successfully. If you’ve connected them properly they’ll function together as follows.

What Happens Now That ESC And Receiver Are Connected?

When you connect your ESC to the receiver you’re going to go in through the throttle channel. Then if you have a BEC built into your ESC it’s going to provide voltage. That is needed by the receiver to power the entire radio system. 

It picks that up through the positive connector and the negative connector of the ESC. So when you connect that in, make sure your polarity is correct. The negative of the receiver is to the far right. So your brown wire on your throttle channel will be off to the right. 

You make that connection once you connect your flight battery. Then it’s going to energize the system through the two wires coming in from the ESC. Unless there’s another outboard switch. Some ESCs do have a little slide switch. It allows you to power the drone radio control system on or off.  

When you’ve got it throttle, it’ll power the entire bus. Most of these receivers have shared buses. The positive and the negative are all connected. Now power up the receiver with the ESC connection to the BEC. It’ll energize all the servos. 

Servos are going to wait for that signal to come from the radio. Which is the farthest left connector. It’s going to look for that signal to be able to actuate or move. But you’ve powered the entire system. That is off of this one feed coming in through the throttle channel. So it’s kind of dual purpose. 

You don’t need to put an external battery on these receivers. It’ll energize just fine off of the feed coming from the ESC of your RC car

We’re hoping you got a better understanding of the whole procedure.


Question: How does an ESC regulate speed?

Answer: An ESC initiates the suitable MOSFETs to produce the rotating force field. Which helps the motor to swivel. Therefore, an Electronic Speed Controller regulates the brushless motor speed.

Question: What does a 4in1 ESC mean?

Answer: ESC’s that have 4 separate ESCs fused. Generally, packed under an FC. It takes care of some intricacy in wiring and a whiff of load as well.

Question: Does my ESC require a BEC?

Answer: Almost all ESCs obtain BEC incorporated in them. An additional BEC is not required if your servo doesn’t absorb a lot of currents. In that case wire your ESC to the battery port.

Bottom Line

Hope this writing will relieve your tension about how to connect ESC to receiver. You’ll realize that it’s not so tough at all.

Wire your ESC carefully to the receiver channel. Your motor will be good to go with an adequate signal from the receiver.
