Key Features

• Sensored Brushless Technology — The motor utilises sensored brushless design with a built-in high-precision magnetic encoder that sends extremely accurate rotor position signals to your ESC, enabling smooth throttle response and precise control even at ultra-low speeds when crawling over technical terrain.
• Precision Magnetic Encoder Sensor — The magnetic encoding sensor boasts accuracy that is 60 times better than traditional sensors found in standard brushless motors, with excellent three-phase signal consistency that delivers accurate rotor position feedback for superior control and smoother operation across the entire throttle range.
• IP67 Water and Dust Protection — Featuring IP67 rated protection, this motor is splash-proof, water-resistant and dust-proof under normal use conditions, allowing you to tackle muddy trails, water crossings and dusty terrain with confidence, though it should not be permanently submerged or exposed to extended water submersion.
• Premium Aluminium Housing — The motor is constructed with a high-quality CNC-machined aluminium shell that provides excellent heat dissipation, durability and protection from the elements whilst keeping overall weight low, which is crucial for maintaining optimal weight distribution in your crawler.
• High-Temperature Enameled Wire — Internal coil winding uses 200°C high-temperature-resistant enameled wire that can handle sustained demanding conditions without degradation, ensuring the motor maintains its performance characteristics even during extended running sessions or high-load scenarios.
• Premium Bearings — The motor incorporates first-line brand high-quality bearings that provide smooth rotation, minimal friction and exceptional durability, reducing mechanical wear and extending the lifespan of the motor even under the stress of intense rock crawling.
• Ultra-Thin Silicon Steel Sheets — First-line brand ultra-thin silicon steel sheets are used in the motor's magnetic circuit, optimising flux density and efficiency whilst minimising core losses, directly contributing to the 11% efficiency improvement over the previous generation.
• High-Toughness Alloy Output Shaft — The output shaft is manufactured from high-toughness alloy material rather than standard steel, providing superior strength and resistance to the torque loads experienced during aggressive crawling, preventing shaft flex and ensuring reliable power transmission.
• Dual KV Options — Available in both 1700KV and 2000KV configurations, allowing you to choose the perfect speed and torque balance for your specific crawler platform and driving style, with the 2000KV variant offering more responsive acceleration and higher top speed.
• 6S LiPo Compatibility — Supporting 3S through 6S LiPo battery configurations, this motor provides enormous flexibility in power delivery and runtime options, allowing you to customise your setup to match your specific performance requirements and play session duration.
• Efficient 4-Pole Design — The 4-pole motor design strikes an excellent balance between torque characteristics and efficiency, providing the crawling power you need whilst maintaining the responsiveness required for technical obstacle navigation.
• Multiple Mounting Options — Built-in with 4 sets of 25.4mm mounting holes plus additional M3/M4 threaded options, the motor provides excellent compatibility with various crawler platforms and can accommodate conversion plates if your frame requires 30mm hole spacing.

Technical Performance

The Hobbywing XeRun AXE 4274 R3 2000KV Sensored Motor represents the pinnacle of crawler motor engineering, combining premium materials with precision manufacturing to deliver a product that performs as impressively as it is built. With a 42mm outer diameter and 74mm length, this compact yet powerful motor produces 4.54A of no-load current when operating, and weighs just 415 grams, making it an ideal direct replacement for existing crawler motors without significantly altering your vehicle's weight balance or inertia characteristics. The 5mm output shaft diameter integrates directly with standard crawler motor adapters and gearboxes, whilst the sensored brushless design with magnetic encoder ensures predictable, smooth power delivery across all throttle ranges. Whether you're running a 3S setup for modest trail performance or pushing a full 6S LiPo configuration for maximum power delivery, this motor scales beautifully across the entire battery range. The 11% efficiency improvement over the R2 generation translates directly to less heat generation, longer runtimes and superior motor longevity — critical factors for serious RC crawler drivers in the UK who demand reliability on demanding terrain. Paired with the Hobbywing XERUN AXE PIUS R3 ESC, this motor system delivers uncompromised performance suitable for genuine 1/8th and 1/6th scale rock crawlers including the popular Axial SCX6, KM Ford Raptor F150, Yikong YK4082 and countless other compatible platforms.

Frequently Asked Questions

• What scale crawler is the Hobbywing XeRun AXE 4274 R3 2000KV motor designed for? — This motor is specifically engineered for 1/8th, 1/6th and 1/7th scale rock crawlers, making it ideal for serious enthusiasts running larger, more capable platforms. The sensored design and IP67 protection make it particularly well-suited to technical terrain and variable weather conditions common in UK off-road RC hobby.
• What is the difference between the 2000KV and 1700KV versions? — The 2000KV variant offers increased responsiveness and higher top-end speed compared to the 1700KV option, delivering 4.54A of no-load current versus 4.0A on the lower KV version. Choose 2000KV if you prioritise speed and acceleration, or 1700KV if you prefer maximum torque and low-speed crawling precision.
• What batteries does this motor work with? — The XeRun AXE 4274 R3 supports LiPo batteries from 3S through 6S configuration, providing enormous flexibility. A 3S setup offers conservative power with excellent runtime, whilst a full 6S LiPo pushes maximum performance and power output. The motor's sensored design ensures smooth operation across all supported voltages.
• Is this motor waterproof and suitable for wet conditions? — Yes, the motor features IP67 protection rating, making it splash-proof, water-resistant and dust-proof under normal use, perfect for muddy trails and water crossings. However, extended submersion should be avoided as it may eventually degrade the protective performance over time.
• What ESC works with this motor? — The motor is optimally paired with the Hobbywing XERUN AXE PIUS R3 electronic speed control, which is specifically designed for the XeRun AXE R3 motor system. This combination delivers seamless integration and optimal performance across all supported battery configurations.
