Compact 2-in-1 Crawler Combo

The WUQ SPMXSEM1040B integrates a brushless motor and a 40A ESC into a single waterproof unit. It is built for scale crawler builders who need a space-saving power system without soldering. The combo accepts 2-3S LiPo or 6-9 cell NiMH packs and includes an adjustable BEC selectable between 6V and 7.4V.

Integrated Protection and Programming

Multi-point safeguards cover over-current, thermal overload, LiPo low-voltage cutoff and failsafe scenarios. Firmware updates and full parameter tuning are handled through the optional Spektrum ESC Programmer Box or the ESC Pro interface. Pro-level drag brake adjustability and RPM throttle matching are configurable for low-speed precision.

2300Kv Motor Rating

The 2300Kv constant defines the motor's speed characteristic and determines gearing choices for a given voltage. Builders targeting higher top speed or different torque curves will need a different Kv value. This specific rating suits typical 1/10 scale crawling applications on 2S or 3S power.

Questions about this item

How often should the 2300Kv brushless motor bearings be inspected or replaced under heavy crawling use?

The sensored brushless motor is sealed for waterproof operation; bearings typically last thousands of run-hours and only need inspection if grit noise appears.

What thermal limit triggers protection first during a long, low-speed climb on 3S LiPo?

The integrated 40 A ESC activates thermal protection when internal temperature exceeds its safe threshold, reducing power before components overheat.

How loud is the cooling fan and how hot does the 40 A ESC casing get during all-day trail runs?

No cooling fan is fitted; the waterproof case runs warm but stays within safe limits thanks to thermal protection and the high-efficiency FOC drive.
