Field-Oriented Control

New sensor technology has changed the feel, performance, and overall tune-ability of the new Axe ESC and Motor in ways some have never experienced. Field-oriented Control is the name of this new tech and is something all new to the scale trail, rock racing, and RC world in general. This new style of the sensor allows extremely accurate control and sensing of the motor while maintaining extreme performance and reliability. The motor and ESC are able to match the RPM of the motor to your throttle position under all driving conditions. This greatly improves downhill driving giving this system the ability to drive downhill under complete control. FOC technology also makes the whole system extremely silent, the motor doesn't create the annoying PWM noise when it is running.


  • Word's First FOC brushless system for Rock Crawler
  • The chip-type magnetic encoder inside the motor guarantees consistency between three phases’ signals
  • The waterproof and dust-proof design (*IP67 standards) allows the AXE brushless power system to be used in all weather and track conditions
  • Intelligent torque output and speed closed-loop control for easy control, and consistent motor RPM
  • The adjustable drag brake and drag brake rate control with the maximum drag brake of up to 200%
  • The innovative built-in Bluetooth connectivity allows users to read ESC data or update ESC firmware via a smartphone
  • The motor with 4 poles and 12 magnets, featuring Hobbywing’s “staggered pole” patent, has zero cogging effect and torque ripple
  • The new sensor harness, which features the plug-and-screw design, has a silicone O ring inside
  • The advanced and secure electronic switch features a waterproof, dust-proof, and shock-resistant design
  • Multiple protections: low-voltage cutoff, thermal, fail-safe (throttle signal loss), motor lock-up, and overcurrent

Intelligent Torque Output and Speed

Not just a new ESC and motor, the new FOC sensors, combined with Intelligent Torque output and closed-loop speed control mean the ESC and motor will maintain the motor’s Torque level and RPM as the conditions of the vehicle change. Uphill, downhill, under load, you name it, your Axe system will do what you’re telling it to do.

Applicable to All Weather and Track Conditions

The IP-67 waterproof rating has been taken to a new level with the AXE System. A completely sealed ESC design with a robust heatsink case design to ensure the ESC is ready for anything you throw at it. The sealed combines a completely new sensor harness. No messy extra steps to make your system waterproof.


Intelligent Torque Output and Speed Closed-Loop Control for Easy Control

Not just a new ESC and motor, the new FOC sensors, combined with Intelligent Torque output and closed loop speed control means the ESC and motor will maintain the motor's torque level and RPM as the vehicles conditions change. Uphill, down hill, under load, you name it, your AXE system will do it!


Patented "Staggered Pole" Rotor Design for Ultra-Low Torque Ripple

The new AXE motor not only has a new sensor design, but uses an improved staggered pole rotor design. What does this mean? Smoother operation with no cogging, and very clean and consistant deceleration. Smoother brakes, smoother power, and transitions between each are improved. This is specific to trail and rock crawling and allows extremely precise throttle control under any load. conditions.


High Driving Efficiency for Long Battery Life

Extremely efficient design comes from the combination of new methods. The FOC sensors provide significant improvements to overall motor performance when compared to standard brushless setups. Runtime is increased dramatically while maintaining exceptional levels of power and response.


Professional Drag Brake Adjustments and Super Parking Capacity

Drag brake rate, and drag brake tuning allows scalers to adjust not only the hill, hold, and drag brake, but how quickly the brake applies. This allows high speed driving without sudden jerks or stops when releasing the throttle. The drag brake itself is super charged, and able to be run at extremely high levels. Compared to a standard crawler brushless setup, the drag brake in the AXE system can be tuned at 200% in comparison.


Innovative Sensor Port

The all new sensor harness is more than just waterproof, and will take on all elements from water to mud to dirt and dust. No need for anything extra, o-ring sealed, and uses a screw together design to ensure it won't come loose.


Built-In Bluetooth for Connecting the Mobile App Directly

Built in connectivity means exactly that. The ESC has Bluetooth built right in! Nothing extra is needed to access the ESC's complete on board programming but your smartphone device and the free Hobbywing App from your app store.


Battery Reverse Polarity Protection

Hobbywing's AXE FOC Crawler system has been designed with a very unique feature protecting your ESC from damage caused by Battery Reverse Polarity, so no matter how many times you reverse the battery connections the AXE ESC and the paired motor are safe from damage.


Built-In High-Precision Magnetic Encoder

A high precision magnetic encoder is used in the motor to ensure precise and consistant information is provided to the ESC. This allows the ESC to have more information from the motor than standard "hall" type sensors and provides improved performance and efficiency.


Available in DifferentSizes and KVs

Five AXE motors, 540-size 1200KV/ 1800KV/ 2300KV and 550-size 2700KV/ 3300KV are applicable to various rock crawlers.
