Overview
The SPM 25A Brushed 2-in-1 ESC / SLT Rx for Grom is a compact, integrated electronic speed control and receiver combo that combines two essential components into one space-saving unit. This is an ideal solution for RC enthusiasts looking to build or upgrade a micro-scale brushed RC car, truck or crawler without the complexity of separate electronics. Whether you're a beginner discovering RC for the first time or an experienced basher looking for a reliable, cost-effective solution for a small-scale vehicle, this 25A brushed ESC with integrated SLT protocol receiver delivers the performance and simplicity you need.
Designed specifically for Grom vehicles and other micro-scale RC cars, this 2-in-1 combo eliminates the need to purchase a separate ESC and receiver, making it an excellent choice for those building a ready-to-run RC car from scratch or upgrading an existing platform. The brushed motor design means this ESC is perfectly matched to brushed motors commonly found in mini and micro RC vehicles, offering reliable commutation and smooth power delivery. With SLT (Smart Lite Telemetry) protocol support, this receiver integrates seamlessly with Spektrum radio systems, ensuring consistent control and responsiveness out on the track or trail.
At just 25 amps of continuous current capacity, this ESC is engineered for the lower power demands of micro and mini-scale RC platforms, making it an excellent fit for Grom vehicles and similar compact designs. The integrated receiver means one less component to fit into tight spaces, which is especially valuable when working with the limited chassis real estate of micro RC cars. This makes it an outstanding choice for UK RC enthusiasts building compact, efficient RC vehicles that still deliver exciting performance.
Key Features
- 2-in-1 Integration — This unit combines both the electronic speed control and SLT protocol receiver into a single compact component, eliminating the need to source and install two separate electronics modules and saving valuable space inside your RC car chassis.
- 25 Amp Current Rating — The 25A continuous current capacity is specifically calibrated for brushed motors in micro and mini-scale RC vehicles, providing adequate power for responsive acceleration and control without oversizing the electronics for your application.
- Brushed Motor Compatibility — This ESC is optimised for brushed motor operation, which means it delivers smooth, reliable power commutation and is purpose-built for the characteristics of brushed motors rather than attempting to accommodate both brushed and brushless designs.
- SLT Protocol Receiver — The integrated SLT (Smart Lite Telemetry) protocol receiver ensures compatibility with Spektrum radio systems and provides a responsive control link with minimal latency, essential for precise handling in RC vehicle operation.
- Designed for Grom Vehicles — This ESC is specifically engineered and sized for Grom platform vehicles, meaning the form factor, mounting provisions and performance characteristics are optimised for this platform rather than being a generic solution.
- Compact Form Factor — The integrated design creates a smaller overall footprint than separate ESC and receiver units, which is crucial for fitting electronics into the confined spaces of micro-scale RC cars and maintaining proper weight distribution.
Technical Performance
The SPM 25A Brushed 2-in-1 ESC / SLT Rx represents a purposefully engineered solution for micro and mini-scale RC vehicle applications. With its 25-amp continuous current rating, this ESC is calibrated to safely handle the power demands of brushed motor setups commonly found in Grom vehicles and comparable compact RC platforms. The brushed motor architecture means the ESC's commutation circuit is specifically tuned for brush-type motors, delivering smooth throttle response and reliable operation across a wide range of driving conditions. The integration of the SLT protocol receiver eliminates separate components, creating a unified electronics package that reduces wiring complexity and simplifies installation in tight chassis spaces. This brushed ESC design means it operates effectively with standard brushed motors without requiring the advanced control algorithms needed for brushless systems, making it straightforward to set up and operate. The LiPo battery compatibility (supporting appropriate cell counts for micro vehicles) ensures you can power this system with modern lightweight battery technology, whilst the SLT receiver protocol provides the connectivity and responsiveness required for precise RC car control whether you're racing on tarmac, navigating trails, or practising crawling techniques. For UK RC hobbyists building compact ready-to-run RC cars or upgrading existing Grom vehicles with modern electronics, this 25A brushed ESC with integrated receiver offers proven reliability and straightforward performance.

Frequently Asked Questions
- Is the SPM 25A Brushed 2-in-1 ESC suitable for beginners building a micro RC car? — Yes, this ESC is an excellent choice for beginners because the 2-in-1 integration simplifies the electronics installation process by eliminating the need to fit both a separate ESC and receiver into a confined chassis. The brushed motor design is also more straightforward to understand and set up compared to brushless systems, making it ideal for those new to the hobby who want a ready-to-run RC car setup without navigating complex configuration options.
- What battery does this ESC require? — Whilst the source does not specify the exact cell count, this 25A brushed ESC is designed for micro and mini-scale vehicles like the Grom, which typically operate on 2-3S LiPo batteries (7.4V to 11.1V). You should consult your specific Grom vehicle documentation or the transmitter documentation to determine the exact battery specifications for your setup.
- What makes this different from the 40A Brushed 2-in-1 ESC? — The key difference is the amperage rating: this 25A model is optimised for smaller, lighter micro-scale vehicles like the Grom with lower power demands, whilst the 40A version is designed for larger or more powerful brushed motor setups that require higher current capacity. The 25A rating makes this model lighter and more appropriately sized for compact platforms, avoiding the bulk and weight of oversized electronics.
- Does this ESC work with Spektrum radio systems? — Yes, the integrated SLT (Smart Lite Telemetry) protocol receiver means this ESC is fully compatible with Spektrum SLT-equipped transmitters, providing secure, responsive control without requiring a separate receiver module.
- Can this ESC handle both forward and reverse? — Yes, as a complete 2-in-1 ESC and receiver unit, this system supports both forward and reverse motor operation, controlled directly from your Spektrum transmitter throttle stick, making it suitable for general RC car driving, crawling and trick manoeuvres.
