FOC Integrated Power System for Crawlers.
(Field Oriented Control)
All-in-one design for optimized length
The design has been integrated and optimized to provide a cleaner and sleeker layout appearance. The overall length is now at 58mm and is 6mm shorter than the previous version. Thes maller footprint has the same length as the AXE540L motor to provide for a spacious and an easy assembly process.
Supports three operating modes
Supports a variety of application needs such as the "constant speed mode (Forward and Reverse)", "normal mode (Forward and reverse with brake)" and "normal mode without constant speed function(Forward and Reverse)"
High Driving Efficiency for Long Battery Life
The FOC drive upgrade increases its entire power system efficiency by 8% while the power consumption loss is reduced by 30% compared with the previous generation. The new 2300KV fusion is significantly more powerful than the previous 1800KV version with an even lower temperature rise while climbing at low speed.
Intelligent Torque Output & Speed Closed-loop Control for Easy Control
The Fusion system is equipped with Intelligent Torque output and Closed loop speed control to maintain the motor’s RPM as the vehicle conditions changes. Regardless of going uphill, downhill or underload, the intelligent output torque senses the operation and allows for simple operation.
Refine parameter items
The ESC is equipped with 13 adjustable parameter items to meet the needs of fine-tuning adjustments. New parameters such as "MAX. Brake Force", "RPM Decrease Rate ", "start mode ( Punch)", "Neutral Range" and other practical parameters are included.
Professional Drag Brake Adjustments & Super Parking Capacity
Fusion pro is equipped with 8-speed drag brake force and 9-speed drag brake-rate adjustment to meet the needs of different models, different field and different handling habits. The maximum drag brake force is about twice of that to the brushless power system of the same size, providing superior parking capability on the slope.
Advanced and Secure Electronic Switch
Compared to the standard on/off switches, the dust, dirt, and waterproof switch housing ensures reliable and longer life. Heavy impact or harsh surface will no longer affect and damaged the switch, eliminating any unwanted damage. Users will be able to enjoy bashing their RC cars.

How does the FOC drive system enhance crawling performance?
The Hobbywing HW30120402 Fusion Pro 2in1 ESC with 2300kV motor and FOC control utilizes field-oriented control to deliver ultra-smooth and silent operation at low speeds. This technology enables precise modulation of torque and throttle, which is critical for rock crawling applications where subtle inputs and terrain feedback dictate performance. Compared to traditional brushless systems, the FOC drive in the Hobbywing HW30120402 brushless combo with waterproof housing and XT60 plug reduces noise and vibration, allowing for a more refined and controlled driving experience. The system’s ability to operate quietly and efficiently makes it ideal for scale builds and technical trail navigation.
Why is the compact 58mm design beneficial for 1/10 scale crawlers?
The integrated layout of the Hobbywing 2in1 crawler motor with 4-pole design and 58mm compact footprint offers significant advantages in space management and installation simplicity. By combining the ESC and motor into a single unit, the overall footprint is reduced by 6mm compared to previous versions, matching the dimensions of the AXE540L motor. This streamlined form factor allows for easier mounting in tight chassis configurations and frees up room for other components such as battery packs or scale accessories. The reduced wiring complexity also minimizes potential points of failure, improving reliability and ease of maintenance for hobbyists and competitive builders alike.
What role does closed-loop speed control play in terrain adaptation?
The Hobbywing HW30120402 with intelligent torque output and closed-loop speed control is engineered to maintain consistent motor RPM regardless of terrain changes or load fluctuations. This feature is especially valuable during uphill climbs, downhill descents, or when navigating uneven surfaces. The closed-loop system monitors motor performance in real time and adjusts output to ensure smooth and predictable behavior. Combined with the intelligent torque output, the ESC delivers responsive power that adapts to the crawler’s operational demands, reducing the need for constant throttle correction and improving overall drivability.
How does drag brake tuning improve slope parking and descent control?
The Hobbywing Fusion Pro ESC with 13 tuning parameters and 9-speed drag brake adjustment includes a highly customizable drag brake system designed to meet the needs of various terrain types and driving preferences. With eight levels of drag brake force and nine levels of drag brake rate, users can fine-tune the system to achieve optimal slope holding and downhill control. The maximum drag brake force is approximately double that of comparable brushless systems, providing superior parking capability on steep inclines. This level of control is essential for scale realism and technical crawling, where precise braking can prevent rollbacks and improve line accuracy.
What makes the waterproof switch housing more durable?
The Hobbywing HW30120402 brushless combo with waterproof housing and XT60 plug features a sealed electronic switch housed in a dustproof and impact-resistant casing. Unlike traditional mechanical switches that are prone to failure from moisture, debris, or physical damage, this advanced design ensures long-term reliability in harsh environments. The switch is engineered to withstand heavy impacts and surface abrasions, making it ideal for outdoor use where terrain conditions can be unpredictable. This added durability enhances the overall resilience of the system and reduces the likelihood of electrical failure during operation.
How does the Fusion Pro compare to previous generations?
Compared to its predecessor, the new Hobbywing HW30120402 crawler system with 60A ESC and 6V/7.4V BEC offers a significant upgrade in both power and efficiency. The 2300kV motor delivers more torque and climbing capability than the older 1800kV version, while operating at lower temperatures during extended use. The FOC drive system increases overall efficiency by 8% and reduces power consumption by 30%, resulting in longer runtimes and improved battery life. These enhancements make the Fusion Pro a compelling choice for builders seeking performance gains without sacrificing reliability or control.
Is the Hobbywing HW30120402 Fusion Pro suitable for competitive crawling?
Absolutely. The Hobbywing HW30120402 Fusion Pro 2in1 ESC with 2300kV motor and FOC control is designed to meet the demands of competitive 1/10 scale crawling.
