In Stock: Usually ships same day
The Spektrum Firma 2‑in‑1 Brushless Crawler Motor/ESC 1400Kv (SPMXSEM1040A) combines a sensored motor and ESC in a compact package that frees up space in detailed scale builds. Engineered for 1/10 crawlers and scalers, it delivers precise low‑speed control, excellent drag brake performance and a robust waterproof design for confident driving in mud, sand, snow and water.
Key Benefits
- 2‑in‑1 ESC motor combo for compact installations
- Advanced sensored motor control for smooth, slow‑speed driving and next‑level drag brake
- Industry‑leading waterproof and dustproof design
- Multi‑point protection: over‑current, LiPo low‑voltage cutoff, thermal and failsafe
Features
- Pro‑level drag brake performance and wide adjustability (up to 200% drag power)
- RPM/Throttle Matching and FOC (Field‑Oriented Control) for 1:1 throttle feel
- Integrated 40‑amp ESC (160A burst) with 2–3S LiPo / 6–9 cell NiMH support
- Fully programmable with optional Spektrum ESC Programming Box (V2)
- Adjustable high‑power BEC: 6V or 7.4V (4A, switch‑mode)
- High heat‑resistant IC3 connectors, backwards compatible with EC3
- Firmware updatable via Spektrum ESC Programming Box
- Compact, ready to install with no soldering required
- Developed by Spektrum engineers with leading ESC and brushless motor expertise
Field‑Oriented Control & Intelligent Drive
A high‑precision magnetic encoder and rotor position sensor enable closed‑loop control, keeping torque and RPM consistent as terrain and load change. The result is confident uphill and downhill control, superb traction management and significantly improved efficiency for longer run times compared with similar sensorless systems.
Compact 2‑in‑1 Design
The integrated layout is similar in size to a 550 can motor, with suggested compatibility for many 1/10 crawler, scaler and trailer models where space is at a premium.

The Spektrum Firma Sensored 2-in-1 System is specifically engineered to be used with 10th scale Crawlers and Scalers. Featuring advanced Field-orientated Control (FOC) and professional drag brake performance and torque control, all while being fully waterproof.
The compact 2-in-1 design grants builders the ability to reduce clutter and components, giving you the most room for scale accessories and customization. The integrated design makes the size similar to a 550 can size motor, making it a easy drop-in option for most 1/10 scale crawler, scaler and trailer models.
Available in a low speed 1400Kv option for extreme slow speed and high angle of attack performance. And a high speed 2300Kv for excellent control for trailers and rock bouncers.
Field-oriented ControlThe Spektrum Firma Sensored 2-in-1 System features a high-precision magnetic encoder and rotor position sensor that provides excellent 1 to 1 control feel when driving at any speed and at any angle. Perfectly suited for trail driving, rock crawling competitions and rock racing setups. This advancement in sensored motor control allows the ESC to match your throttle input to the motors RPM with unmatched precision.
Intelligent Speed And Torque Control
The Spektrum Firma Sensored 2-in-1 System provides a closed loop control, ensuring that the esc maintains torque and RPM levels even as driving conditions change. Giving unprecedented control when driving uphill or downhill and even when in wet or loose traction conditions. No matter the terrain, the Spektrum Firma Crawler system keeps you in complete control.
Maximum Power Efficiency Provides Longer Battery Life
When driving with the Spektrum Firma Sensored 2-in-1 System, drivers are better equipped for the long trails ahead. The Spektrum Firma Sensored 2-in-1 System only uses the power it needs to match your desired throttle output, providing substantially more efficient current levels and extremely long battery life when compared with similar sensorless systems.
Pro-Level Drag Brake Adjustment
The Spektrum Firma Sensored 2-in-1 System features a huge range of drag brake adjustability, allowing for drivers to expertly tune their crawlers and scalers depending on their driven train and vehicle weight. Allowing up to 200% drag power, no matter the setup, the Spektrum Firma Sensored 2-in-1 System can keep your vehicle parked at nearly any incline.
Waterproof
The all-weather, waterproof design of Spektrum™ Firma™ ESCs allows them to perform in nearly any terrain under almost any conditions. Firma ESCs keep you going through dust, gravel, snow, and water.
High-adjustability Programming Options
Using the Spektrum ESC Programming Box (version V2 required) , you can easily change settings on the trail to suit driving conditions. An easy-to-use Smart Link USB Updating and PC Programmer app is also available.
