How does this combo enhance drag racing performance?
The Spektrum P-SPMXSEMC13 brushless combo with 100A continuous ESC, 650A burst, and Text Gen transmitter programming is specifically sourced for Stock and Pro Class 2S drag builds. The 6500Kv sensorless motor delivers rapid acceleration and high top-end speed, while the 100A ESC ensures consistent power delivery under load. With preinstalled 4mm bullet connectors and no-solder installation, setup is fast and clean. The system is pretuned for drag racing, allowing drivers to hit the strip with minimal configuration and maximum confidence.
What telemetry data does the Smart system provide?
The Smart ESC/motor combo for Losi 22S No Prep and 2WD drag kits with telemetry feedback and drop-in fitment transmits vital performance metrics directly to your Spektrum transmitter. Through a single-wire connection, users receive real-time updates on RPM, ESC temperature, battery voltage, and capacity. When paired with a Spektrum Smart LiPo battery, telemetry expands to include cycle count, cell voltage, and remaining charge. This data enables racers to fine-tune their setups and monitor system health without additional sensors or modules.
How does transmitter-based programming simplify tuning?
With proprietary Text Gen integration, the Spektrum digital ESC/motor system with 650A burst, 4mm motor leads, and no-solder install allows users to configure ESC settings directly from compatible Spektrum transmitters. This eliminates the need for external programming boxes or Bluetooth modules. Drivers can adjust timing, braking, throttle curves, and cutoff thresholds on the fly—ideal for trackside tuning and rapid setup changes. The system also supports SmartLink USB and ESC Programming Box for users who prefer PC-based configuration.
Is the Spektrum P-SPMXSEMC13 suitable for wet or dusty conditions?
Yes. The Spektrum P-SPMXSEMC13 waterproof ESC/motor system with Smart telemetry, IC5 input, and 4mm motor bullets features a sealed housing that protects internal electronics from moisture, dust, and debris. Whether racing on damp asphalt or through loose gravel, the waterproof design ensures consistent performance and long-term reliability. The aluminum heat sink and optional cooling fan maintain thermal stability during extended runs, while the IC5 connector ensures secure power delivery under high current loads.
What makes the motor design ideal for high-speed builds?
The Spektrum P-SPMXSEMC13 with 6V/7.4V selectable BEC, 136g weight, and CNC-machined motor housing includes a 6500Kv brushless motor built for speed and durability. Its 4-pole, 8-magnet rotor delivers smooth torque and rapid acceleration, while the CNC-machined aluminum housing enhances heat dissipation. The 3.175mm alloy steel shaft and precision bearings ensure reliable rotation under stress, making it ideal for drag racing and speed run platforms. Preinstalled 4mm gold-plated bullet connectors simplify installation and ensure low-resistance power transfer.
How does the ESC support consistent power delivery?
The 100A Smart ESC provides stable current for high-RPM applications, with a burst capacity of 650A to handle throttle spikes. The switch-mode BEC supplies 4A continuous current at selectable 6V or 7.4V, supporting a wide range of servo configurations. Integrated protection features include over-current, thermal shutdown, low-voltage cutoff, and failsafe logic—ensuring safe operation during demanding runs. Firmware updates via SmartLink USB or ESC Programming Box keep the system current with the latest performance enhancements.

We want to make sure your delivery goes smoothly, so here are some important details about our service:
- For orders above £120, we offer delivery to most mainland UK addresses. For orders under £120, we can still deliver to Northern Ireland and the outlying isles, as long as the item can be sent by Royal Mail, weighs less than 30kg, and fits within 61cm × 46cm × 46cm. Some highland and remote areas may carry an extra delivery charge as couriers often apply surcharges in these locations. If you live in one of these areas, feel free to contact us before ordering so we can confirm the delivery options and costs for you.
- Most of our products include delivery in the price. If your order is under £90, a small delivery fee will apply but do not worry this will always be clearly shown at checkout before you complete your purchase.

Orders are dispatched Monday to Friday only. Some items may take a little longer and if that is the case we will always show the expected delivery time on the product page.
- If your order includes items with different dispatch times we will normally wait and send everything together once all items are in stock. If one of the items is going to take a while we will give you the choice either wait for everything to arrive or let us send the available items now and deliver the rest later. It is up to you.
- We use trusted delivery partners to make sure your order gets to you safely and on time. We use DPD for next working day deliveries and Royal Mail for the 2 day option.
- As soon as your order is on its way we will send you a tracking number by email. If you provide your mobile number at checkout we will also send delivery updates straight to your phone so you can keep an eye on progress.
