If you've been researching and looking for a serious electric RC excavator, and you continue to come across these two names, you are not the only one. It's quite common to find the Double E EC160E vs Kabolite K5901 racer topic popping up again and again in the RC construction world. They're both fantastic machines, available from Heavy Duty RC, and they'll both make you look twice at any job site session. They're designed for different types of buyers, though, and knowledge of the distinction will prevent you from investing in the incorrect machine.
What is the Double E EC160E?
The Double E Volvo EC160E is a 1:14 scale, fully official, fully zinc and aluminum alloyed Volvo RC digger. One of the most detailed electric RC models in its class, it has a fully functional cab door, proportional track control through dual rotary transmitter inputs, and digging power that Heavy Duty RC says is almost equal to hydraulic excavators of that type. The arm consists of solid material and is therefore more stable and has a nice weight when it is running.
The EC160E is unique in having an authentic Volvo license, metal construction, and a nice entry point for buyers who wish to have a high-quality feel without going all the way to the top of the hobby. A more well-balanced and accurate size than many of its electric counterparts, and the driving realism it conveys via the proportional controls makes this a popular choice among new and intermediate collectors.
What is the Kabolite K5901?
The Kabolite K5901-100S is an electric RC scale 1/18 excavator model, which is the next generation of the Huina 1599 model line now manufactured under the Kabolite brand. Its weight is approximately 9.9 to 12 kg, depending on configuration, and the body is a 99% metal construction with a 23-channel control system, a Flysky 2.4 GHz radio, and a planetary reduction gearbox for smooth 360-degree rotation. Out of the box, versatility is the name of the game with the K5901, which is shipped with interchangeable tools like an electric hammer, ripper, and electric claw.
It is at this stage that things get interesting. The K5901 shares many characteristics with Kabolite's own K970 series, such as a new power transition system and a more powerful servo system. It is basically the same V5 build of the Huina 1580, but now with top-notch Kabolite engineering.
Why Does the Kabolite K5901 Cost More?
The differential is not a fig leaf, and it is fair. Let's take a look at what you're paying for with the K5901. First, the channel count is much higher, 23-channels, so it can be much more independent and exact control over all arm movements. Secondly, the presence of three interchangeable working attachments provides actual working versatility that is not available with the EC160E "straight out of the box. Secondly, the presence of three interchangeable working attachments provides actual working versatility not available with the EC160E "straight out of the box". Thirdly, the radio system used in the K5901 is one step higher than the previous one in terms of the accuracy and smoothness of radio control. Fourth, this platform has a Kabolite brand engineering already integrated in it, which is a testament to the manufacturing company's R&D investment.
The K5901 is not only heavier and more powerful, but it's also more complex with more moving parts, more electronics, and more real-world simulation added in. It costs money to be that complicated.
