  • Product typeModels & Kits
  • Smart telemetry delivers RPM, temperature and voltage data
  • 32-bit ARM M4 processor enables fast, responsive control
  • Waterproof construction protects electronics in wet conditions
  • 150A continuous current rating handles high-power demands
  • 2050Kv sensorless motor provides strong acceleration

Smart ESC & Motor Combo

This brushless combo pairs a 150A electronic speed controller with a 2050Kv sensorless motor. It targets RC enthusiasts who want integrated telemetry without adding separate sensors or wiring looms. The 32-bit ARM M4 processor handles real-time data logging and motor management.

Waterproof Build & Programming Options

The sealed casing protects the electronics from water and debris during off-road or marine runs. Users can tune parameters via the onboard button, a dedicated programming box, SmartLink USB or the PC programmer application. A single telemetry wire delivers RPM, temperature, voltage and capacity to compatible Spektrum Smart receivers.

Replaces Separate ESC, Motor & Telemetry Modules

Builders upgrading from standalone analogue speed controls gain a unified power system that reports live data through one connection. The jump is worth it when you want plug-and-play Smart ecosystem integration and onboard logging without fitting extra hardware.

Questions about this item

What does the 150 A rating on the ESC cap in practice?

The 150 A rating is the maximum continuous current the ESC can deliver to the motor; the 32-bit ARM M4 processor monitors temperature and voltage in real time to protect the unit if that limit is exceeded.

What physical space does the motor need to mount?

The sensorless motor fits standard 1/8-scale motor mounts; its black anodised can and shaft dimensions match common 5 mm pinion patterns used on buggies and trucks.

How is the combo installed, and what step do people skip?

Solder the battery connector, bind the ESC to a Spektrum Smart receiver, then use the button or SmartLink USB to set the LiPo cutoff before the first run — many forget the cutoff and risk over-discharging the pack.
