INJORA MB100 G2 Waterproof 40A Brushed ESC for 1/24 1/18 RC Crawler

Well pleased with item a lot better then stock and now i can run a traxxas lipo in my scx24 ! would buy again

Una gran mejora sin duda, mucho mejor tacto para escalar. Junto con los engranajes 40 3/1 de acero y el motor 180 48T genial para escalar con el Traxxas TRX4M

Pour mon crawler 1:18, c’est l’idéal.

The INJORA MB100 G2 is an impressive upgrade for anyone looking to get more control and customization out of a small-scale RC crawler. I purchased this ESC for my Traxxas TRX-4M Bronco build, and one of the biggest selling points for me was the combination of its compact design, performance capabilities, and Bluetooth connectivity for programming through the INJORA Link app. Compact Design With Impressive Capabilities Space is always at a premium when building a heavily modified 1/18-scale crawler. Between aftermarket chassis components, upgraded axles, steering servos, battery placement, and other electronics, finding room for everything can become a challenge. The MB100 G2 has a compact footprint measuring approximately 25.2 × 18.3 × 14 mm and weighs just 10 grams. Despite its small size, it offers a rated continuous current of 40A and a peak current of 100A, making it a capable option for compatible brushed-motor builds. It supports a range of brushed motors and 2S–3S LiPo batteries, giving builders flexibility when selecting their power system. It is also rated IP67 for water and dust protection, which is a welcome feature for a crawler that may encounter damp terrain and outdoor conditions. Bluetooth Connectivity and the INJORA Link App Are Major Advantages One of my favourite features of this ESC is the ability to connect to it through the INJORA Link app on a compatible smartphone. Instead of being limited to the factory settings, you can access adjustable parameters directly through the app and tailor the ESC to suit your vehicle, motor, and driving preferences. This is a significant advantage for crawler enthusiasts because low-speed control, braking behaviour, and throttle response can make a real difference when navigating technical obstacles. The app provides access to ESC tuning options, including throttle and braking parameters, BEC voltage adjustment, and other configuration settings. Bluetooth connectivity also supports real-time tuning, data logging, and firmware updates. Being able to configure the electronics through a smartphone makes the process much more convenient than relying on complicated programming procedures or purchasing separate programming hardware. Adjustability Makes This ESC Particularly Appealing for Crawling Different crawling situations can benefit from different ESC settings. When navigating rocks, ledges, and technical obstacles, predictable throttle response and suitable drag-brake behaviour are particularly important. Being able to adjust the ESC allows you to work toward a setup that better suits your driving style. The adjustable BEC output is another important feature, with a specified range of 3.0–8.4V. This provides flexibility when configuring a compatible receiver and servo, provided their voltage requirements are respected. For builders running aftermarket steering servos, this is especially useful because different servos have different operating-voltage requirements. Having these adjustments available through the app gives you more control over your electronics setup and makes it easier to customize the system as your build evolves. Waterproofing and Built-In Protection The IP67 rating is another positive feature for a crawler-oriented ESC. The unit also incorporates several protection functions, including low-battery or undervoltage protection, overheat protection, overvoltage protection, and protection against loss of the receiver’s throttle signal. These features provide an additional layer of protection for the electronics and are welcome in a vehicle that may be driven over challenging terrain. As with any electronic component, waterproof-rated does not mean maintenance-free. I would still recommend inspecting connections and drying the unit after exposure to water to help prevent connector corrosion. An Excellent Option for a Custom TRX-4M Build For anyone upgrading a TRX-4M or another compatible small-scale crawler, the MB100 G2 offers an appealing combination of compact dimensions, current capacity, adjustable settings, and smartphone-based programming. I particularly like the flexibility offered by the app. Rather than simply installing an ESC and accepting its factory configuration, you have the opportunity to tailor the electronics to the needs of your build. This becomes especially valuable when upgrading multiple components and wanting the electronics to work together as a properly configured system. Keep in mind that the MB100 G2 is designed for brushed motors, and replacing the factory ESC generally requires a compatible transmitter and receiver. Check the wiring and compatibility requirements before installation. Final Verdict The INJORA MB100 G2 is a feature-rich ESC that offers much more than a basic electronic speed controller. Its compact size, substantial rated current capacity, IP67 protection, adjustable BEC output, and Bluetooth app-based tuning make it an attractive option for enthusiasts who want greater control over their small-scale crawler. The INJORA Link app is a particularly appealing feature because it puts a range of configuration options directly at your fingertips. For hobbyists who enjoy fine-tuning their vehicles and getting the most out of their builds, this ESC offers an impressive combination of features in a very small package. A well-designed upgrade for anyone looking to take their compatible brushed crawler electronics to the next level.

Bad supply batch. INJORA Brushed Mini ESC 20A Instantly started smoking and blew a hole out of the side. I had it paired with an Injora 050 50T brushed motor. The motor is fine and still works great.
