Axial SCX24 Electronic Upgrades

Our Axial SCX24's electronics are being upgraded. In this post, we'll demonstrate three easy electronic upgrades for the Axial SCX24 crawlers. We have implemented several adjustments to reduce our kits' centre of gravity. However, to manage the weight and improve performance, we must now upgrade the electronics.

What servo upgrades did we choose for our SCX24 Deadbolt?

The EcoPower 827 digital micro servo will replace the stock steering servo. This servo has a plastic horn and can handle high voltage. Furthermore, it has far more power than the stock one. A more powerful servo is essential when adding a lot of weight to the truck or in hard terrain.

*If the white servo horn bothers you, you can paint it black like we did; we favour a stealthy blacked-out appearance. Make sure to use paint made specifically for plastic, like Tamiya's TS-Series.

Adding a SCX24 Servo Mount

We wanted a more robust steering system, so we added aluminium steering links from Yeah Racing for support and chose a servo mount from Hot Racing, which is necessary for the EcoPower 827 servo.

When completed, the servo modification significantly enhances the steering feel and reaction.

What servo did we choose for our SCX24 Jeep?

We also replaced the servo in our SCX24 Jeep with an Emax small 12g servo, which is more powerful than the factory Axial servo and an excellent choice if you've added a lot of weight to the front end or need additional steering force for extreme crawling.

We also fitted our Wrangler with the EMax/EcoPower servo mount.

What batteries are available for the SCX24?

A few battery upgrade options are available to increase runtime. We wi h to update because the battery that came with our tiny crawler only has 350mah of capacity. We have three choices: the EcoPower Trail Pack (450mAh), Common Sense (450mAh), and Venom (430mAh). Driving time should be significantly longer with either of these batteries than with the factory one.

What batteries did we choose for our Axial crawlers?

We purchased a couple of EcoPower trail batteries since we want our trucks to have a longer runtime. They're close to the OEM pack's precise dimensions. It is a minor compromise for longer runtimes, but it is only somewhat thicker and heavier.

We upgraded our SCX24 speed control!

We will be replacing the Electronic Speed Control (ESC) on our SCX24 Deadbolt to increase performance even further. The L card 20A and Tegu 20A are two new Furitek ESC units that can be used with or without brushes. The Lizard and Tegu ESCs use field-oriented control (FOC) to provide steady and strong torque. In addition, each has a high-speed dynamic response, low noise, and high efficiency.

The FuriCar app combines your smart device with the Bluetooth module that comes with each ESC. It enables you to view telemetry data, make changes, and receive firmware upgrades. The Fritek Tegu features a more durable BEC and is the largest and heaviest of the two ESCs. This will enable you to power a 3S LiPo battery and additional lights.

What ESC did we choose for our Deadbolt?

We fitted the Lizard 20A ESC, which is lighter and smaller, on our truck while keeping the standard motor. We installed the speed control on top of our basic unit. With no weight gain, this ESC is noticeably smoother than the previous one.

Summary

These are the three easy-to-follow SCX24 electrical upgrades. Could we have improved our SCX24 Deadbolt's electronic system further? Yes, but with the new ESC, battery, and servo, our tiny crawler is performing admirably.

For our purposes, we discovered that the factory motor operated flawlessly. If you're game, though, there are a number of motor options available. Always remember to conduct your research and take your time. Upgrading should be enjoyable if you have the appropriate tools.
