Do you recall the moment you realized how much you needed an SCX24? I’m sure you would have loved the car’s performance on the carpet.
As you gained experience, you would have come to value the reliability of the driving motor more highly than its initial performance.
Are you looking for a scx24 brushless motor upgrade?
You can start upgrading to a censored motor to increase accuracy and control. You can also try higher-wattage motors for more power. A higher KV motor will surely help with speed. Do check your operating and stalling currents while upgrading. Finally, don’t forget to upgrade your ESCs as well.
That will be the summary of everything. We will get into the details in this article. Stick with us till the end to find out more.
Things to Consider Before the SCX24 Brushless Motor Upgrade
Despite its diminutive stature, the Axial SCX24 has emerged as a fan favorite among R/C crawling and trail-driving enthusiasts. This gear is ready to go to work immediately. If you want your little vehicle to be even more effective, you can get it upgraded.
The motor is one of the first things you will want to upgrade. However, you will need to consider a few things before you jump into the motor upgrade.
We have jotted them down just for your convenience.
Motor Size
You can’t just pick any old motor for your RC. The size of the motor itself has to be a deciding element.
First, check the motor case for the motor’s dimensions to make sure the new engine will fit. In most cases, the size of the motor will be denoted by a number in the format ’24-07,’ for example.
The motor width is 24, and the motor height is 7.
It’s worth noting that larger motors provide more torque. This is why beginners in the RC hobby often choose larger motors. The problem with larger motors is something few people consider.
A larger motor means more weight for your remote-controlled car. You’ll need a more sturdy chassis to withstand crashes now that your RC will have a lot more momentum to deal with the added weight.
An improved suspension and braking system would be necessary.
This means your RC will gain speed. Better chassis for impact protection springs for stability and brakes are required.
Operating Current & Stall Current
The current flows through the windings of the motor and provides the energy necessary to turn the shaft. The operating current of a motor is the average amount of power. It is designed to be consumed when operating at a given torque level.
Radio-controlled aircraft and helicopters benefit from stall currents. For the aircraft or helicopter to operate at stall speed, or zero revolutions per minute (RPM), the motor must be able to draw this much current.
The design of heat sinks relies on knowing the motor’s ideal operating current and stall current, which helps avoid melting the coils.
Motor Wattage
Total motor power is measured in watts. If the wattage is high, the motor will be strong. If you’re solely intending on upgrading the motor, double-check the Electronic Speed Controller’s rating (ESC).
The ideal ESC rating is at least 20% higher than the motor’s wattage. An ECS capable of handling at least 30A would be necessary for a motor that draws 20A.
Sensored vs Sensorless Motors
The electronic regulator supplies current to the brushless motor. A smooth start-up from 0 RPM requires the speed control (ESC) to be aware of the rotor’s location.
The rotor’s position must be determined by the ESC if it is not already known. As the rotor rotates, the ESC sends power to the motor.
Then it measures the resulting Electromotive Force (EMF). This is really simply a voltage “signal” delivered back to the ESC. The rotor’s location can be understood by the ESC thanks to this feedback loop.
As the name suggests, sensors are built into a sensored brushless motor’s design. The rotor’s location is reported by these sensors to the ESC. When the ESC has rotor position information, synchronization can begin at 0 RPM.
ESC Compatibility
The Electronic Speed Control (ESC) is a link between the battery and the motor. It’s nearly like the role of the negotiator.
When linked to the receiver, it picks up signals from the control unit, instructing it on how much electricity to discharge. That’s why it’s crucial that the ESC can take a large amount of power without being damaged.
Therefore, you should also upgrade your ESC at the same time you upgrade your motor. Consider the wattage, maximum amps, and continuous amps of the motor you’re considering.
Then, look for an ESC that exceeds your requirements just in case. Typical motors draw 150A (Amps) of constant current.
Hence, a suitable ESC would need to be able to manage 170A or more. Don’t worry too much about this, though, because you can easily find out what kind of ESC you need on the internet or in a store.
Recommended SCX24 Motor Upgrades
Here are some recommended upgrades for the SCX24.
| Aspect | For Climbing | For Racing | For Bashing |
| Sensor | ✓ | ✓ | ✓ |
| ESC | ✓ | ✓ | |
| Turns | Less Turns | More Turns | Less Turns |
| KV | ✓ | ✓ |
Upgrading SCX24 For Racing
Improving your RC racer’s acceleration and top speed will be top priorities. As a result, we will advise that you replace your current motor with a sensored one.
A sensored motor guarantees consistent output, which is critical for performance. Likewise, if you upgrade to a more powerful motor, your vehicle will move faster and have more force at your disposal.
Also, make sure your electronic speed controls (ESCs) are up to date.
Upgrading SCX24 For Climbing
Climbing may be the most upgrading SCX24 For Bashinghallenging task for a radio-controlled vehicle. There needs to be more torque and horsepower, but also more grip for this.
Thus, upgrading to a less-turn motor will make your car capable of ascending. If you do this, you can count on having plenty of torque and grip.
You’ll also need a robust ESC and an extra KV. When rock climbing, a higher KV rating means more of a kick. Incorporate sensors into the design of the motor.
More horsepower and torque are needed when upgrading your motor for bashing. Since this can cause power outages, we recommend using sensorless motors instead.
In addition, you’ll gain a lot from a motor that has fewer revolutions.
FAQs
Are All Scx24 The Same?
All SCX24 models are, essentially, the same underneath the skin. Everything from the electronics to the motor to the servo to the receiver is universal across all vehicles. The frame, springs, and wheels are all identical. The difference is in the outlooks.
Can I Replace A Brushed Motor With A Brushless One?
Yes, you can. Getting a new brushless motor is the first step toward making the switch from brushed to brushless. The motor itself cannot be modified to operate with either fuel type. Also, the ESC is a different kind. You need to change it if you’re using brushless motors.
Do I need a new ESC for a brushless motor?
Yes, a brushless electronic speed controller is required for a brushless motor. An ESC capable of handling the motor’s current draw is required. If it claims to be able to handle up to 14 amps, then it can. Hence, you need a new piece of ESC.
Conclusion
That will be all for the SCX24 Brushless motor upgrade. You should now be fully equipped to upgrade the motor in your RC car.
Before moving on to the upgrades, make sure you check the compatibility. And don’t forget to maintain them properly.
See you soon.
