Step-by-Step Guide: How to Connect RC Speed Controller

Ah, the thrill of controlling an RC device, be it airborne or terrestrial! But that exhilarating command, friends, comes from a gadget often overlooked – the RC speed controller. Acting as the heart that pumps life into our RC devices, it’s a little magic box that swiftly interprets your command into an accurate motor action. Now, according to, a leader in the RC hobby kingdom, there’s indeed quite a varied range of these speed controllers available. From flying gliders to racing cars, they’re as diverse as the world of RC itself. The key here is to opt for the right one, the one that best suits your device and your ambition to rule the RC roost. Think of it as matching the right jigsaw piece in a complex puzzle. Get it right, and voila! Your device operates at peak performance. And if you get it wrong? Let’s say you’re more likely to hit a roadblock than the finish line. So, let’s navigate this RC road together, shall we?

Choosing the Right ‘Brain’ for Your RC Device

Let’s think of the RC speed controller as the ‘brain’ of your RC device. Just like your brain transmits signals to different parts of your body, the RC controller sends commands to the device, controlling its movement and speed. There are two main types of speed controllers: brushed and brushless. The brushed ones, as the name suggests, use brushes to deliver current. They are budget-friendly, but wear out more quickly due to the mechanical wear and tear. Brushless ones, on the other hand, utilize magnets and are more efficient, but they come with a heftier price tag. Now, if you go to Amazon or HobbyTron, you’ll find a range of speed controllers with different features and price points. It’s not about which one is better overall, but which one is better for you. Consider the type of RC device you’re using and what you’re willing to spend. Or perhaps, like an RC enthusiast I once met, try out both kinds and make the choice yourself. Remember, when you’re learning how to connect an RC speed controller, the first step is choosing the right ‘brain’ for your device.

What are the differences between brushed and brushless RC speed controllers?

Well, pal, you’ve come to the right place! Brushed and brushless RC speed controllers can appear pretty similar to the untrained eye, but there are some key differences you should know about. Picture it like this – brushed controllers are like that old but reliable coffee machine, doing the job, but perhaps lacking some of the snazzy features of the newer models. They’re simple, serviceable, and cost-effective, but they do tend to wear down over time as the brushes inside get ragged.

On the other hand, brushless RC speed controllers are like the barista-quality espresso machine you’ve been eyeing up. They’re efficient, smooth, and remarkably durable, thanks to not having those wear-prone brushes. Sure, they might cost a bit more, but they do provide better performance and longevity.

Now, you need to consider your needs. If you’re just starting with RC and want to dip your toes in the water without splashing too much cash, a brushed controller might be your go-to. But if you’re a bit of a pro, or someone who loves a smooth, high-performing RC unit, then the brushless controller might just be worth the investment.

Remember, connecting your speed controller could be a bit tricky, particularly for the brushless ones. It’s like doing a complicated jig-saw puzzle but once you get the hang of it, you’ll have it down pat. Just keep at it. This decision isn’t just about the technical differences, but also what feels right for you. Adventure is the spice of life, after all!

Connecting Your RC Speed Controller

Alright, let’s get our hands on the connection process for RC speed controllers. It’s time to navigate the intricate circuitry of technology, and the journey is thrilling. Grab your trusty Phillips-head screwdriver and your new speed controller, breathe in, and let’s get this show on the road. The first thing you need to do is identify your power source, and connect it to the controller using the plug provided. If your controller is brushless, the three wires on the controller align with the three wires on the motor. With a brushed controller, you only have two wires to worry about. You’re essentially playing matchmaker here, connecting each wire to its corresponding color on the motor. So, let’s say you have a red wire and a black wire on your controller. The red wire is the “positive” wire, and it’s going to connect to the positive terminal on your motor. The black wire is the “negative” and takes up residence on the negative terminal. To make sure your connections are secure, you’ll want to solder them together. You’ve essentially given your RC device its heartbeat. Amazing, isn’t it?

If you’re new to this, you may find yourself a little puzzled at this stage. Fear not, my fellow RC enthusiast! Let’s untangle the wires to your query, literally. Start by looking toward the heart of your device, the motor. It’s here that you will find three wires, color-coded as yellow, red, and black. Now, find a thin three-wire cable hanging out of your speed controller. Match the colors and voila! You’ve just made a connection. But, this is just the first leg of your journey. We’ll need to establish its communication with the receiver next.

Typically, you will find the speed controller marked ‘CH2’ or ‘Throttle’ on your receiver. If you have a look at your speed controller, on the opposite end you’ll find a three-wire cable with a plug. This plug goes into the receiver’s throttle channel. Do you see it coming together?

Here’s where it starts getting a bit tricky – power source. We need to connect the RC speed controller to a battery for power supply. The battery will most likely have a pair of red and black wires. These are to be connected with the battery ports on the speed controller, also with a red and black wire. Remember, red to red, black to black.

Always bear in mind, in the vast universe of RC electronics, matching wire colors are like beacons guiding us to the correct connection. In this labyrinth, they are your lifelines. For more visuals or a step-by-step instruction, I highly recommend a quick visit to They have some great resources to help guide you on how to connect RC speed controller.
