Key Features

• Spiral Groove Heat Dissipation Structure — The motor casing features an innovatively designed spiral groove pattern that improves cooling efficiency during extended running sessions, ensuring the motor maintains optimal operating temperatures and delivers consistent performance lap after lap. This elegant design also provides visual appeal, making your RC car look as good as it performs.
• 8S LiPo Compatibility — Supporting up to 8S LiPo battery packs (with 3S minimum), this motor is built for high-voltage performance whilst remaining versatile enough for lower-voltage setups. This flexibility means you can tune your power delivery to match your driving style and track conditions, whether you need controlled acceleration or maximum top-end speed.
• Sensorless Technology with Linear Low-Speed Response — The SD (sensorless) design delivers great response and a linear feel even at low speeds, allowing your RC vehicle to execute precise maneuvers with excellent control. You'll experience smooth acceleration characteristics and predictable handling whether you're performing hard launches, maintaining straight-line speed, or executing jumps.
• Dual Connector System — The motor ships with 6.5mm connectors pre-installed, but includes additional 8mm connectors for compatibility with larger ESC systems like the EzRun MAX5 HV G2 and MAX6 G2. This dual-connector approach eliminates the need for expensive adapter cables and ensures seamless integration with your existing RC setup.
• IP67 Waterproof and Dustproof Rating — The new sensor line interface features enhanced waterproofing that reaches IP67 protection level, meaning the motor offers splash-proof, water-proof, and dust-proof performance under normal use. This all-weather capability allows you to tackle various environmental conditions and harsh terrains without worrying about moisture damage to critical components.
• Modular Design for Easy Maintenance — The motor adopts a modular structure with separate front end set, stator set, rotor, and rear end set components. This design makes daily cleaning and maintenance quick and straightforward, effectively prolonging service life and maintaining working efficiency throughout the lifespan of your motor.
• Premium Build Materials — Constructed from high-hardness aluminium CNC components, ultra-thin silicon steel sheets, high temperature-resistant oxygen-free copper wires, and high-strength Kevlar fibre-wound explosion-proof rotors with durable alloy output shafts. These quality materials guarantee reliable performance and longevity even under extreme racing conditions.
• High-Precision Bearing System — The motor features professional-grade bearings (D22×D8×T7 front and D19×D8×T6 rear) that ensure smooth rotation, low friction, and extended operational life. Quality bearings from top brands are essential for maintaining efficiency and reliability during competitive racing or aggressive bashing sessions.

Technical Performance

The Hobbywing EZRUN 5690SD G2 delivers exceptional technical specifications that make it one of the most capable brushless RC motors available in the UK market today. With a 1250KV rating, this motor provides the perfect balance between torque and top-end speed, making it ideal for 1/5th and 1/6th scale applications ranging from short course trucks to light-load truck platforms. The motor measures 56mm in diameter with a 90.2mm length and features an 8mm shaft diameter, with a total weight of 867g including the three black 8AWG wires (each 250mm in length). Designed to handle up to 43,000 RPM, the EZRUN 5690SD G2 supports 3-8S LiPo battery configurations with a no-load current draw of just 6.6A, making it highly efficient and compatible with a wide range of ESC options. The four-pole brushless design ensures smooth power delivery and minimal vibration, whilst the sensorless technology operates independently without external sensors, reducing complexity and potential points of failure. This motor is specifically recommended for use with EzRun MAX6 G2 or EzRun MAX5 HV G2 ESCs to achieve optimal performance, and the flexible connector system ensures compatibility with most modern RC car systems whether you prefer 6.5mm or 8mm connectors.

Frequently Asked Questions

• What is the difference between the sensorless 5690SD and sensored motor options? — The EZRUN 5690SD G2 is a sensorless motor, meaning it doesn't require sensor wires to operate and relies on back-EMF detection for commutation. Sensorless motors are simpler, more reliable, and less prone to sensor-related failures, making them excellent choices for bashers and competitive racers who value durability. The trade-off is that sensored motors typically provide slightly better low-speed torque characteristics, but the EZRUN 5690SD G2 compensates for this with its linear low-speed response and excellent control delivery.
• Is this motor suitable for beginners to RC cars? — Whilst the EZRUN 5690SD G2 is a high-performance motor designed for 1/5th and 1/6th scale trucks, it's suitable for drivers of all experience levels. The linear power delivery at low speeds makes it forgiving for newer drivers learning throttle control, whilst the support for 3-8S LiPo batteries means you can start with lower voltage setups and progress to higher power as your skills develop. The modular design and IP67 protection make maintenance straightforward even for RC car enthusiasts just starting their hobby.
• What battery voltage should I use with the EZRUN 5690SD G2? — This motor supports 3S to 8S LiPo batteries, giving you significant flexibility in power levels. A 3S LiPo (11.1V) configuration provides controlled, manageable power suitable for learning and technical driving, whilst 6S (22.2V) and 8S (29.6V) setups deliver maximum performance for racing and aggressive bashing. Your choice should depend on your vehicle's ESC capability, the intended use case, and your comfort level with high-performance setups.
• Will this motor work with my existing ESC and battery? — The EZRUN 5690SD G2 is compatible with most modern ESCs that support brushless motors, but Hobbywing specifically recommends pairing it with EzRun MAX6 G2 or EzRun MAX5 HV G2 ESCs for optimal performance. The motor comes with 6.5mm connectors pre-installed, and includes 8mm connectors for larger ESC options. Confirm your ESC's maximum voltage rating (at least 8S if you plan to use the motor at full potential) and connector type before purchasing.
• How do I maintain the EZRUN 5690SD G2? — The modular design makes maintenance simple and straightforward. The motor can be disassembled into its front end set, stator set, rotor, and rear end set for easy cleaning and inspection. Regular maintenance—removing dirt and debris, checking for bearing play, and ensuring connectors are clean and secure—will effectively prolong the service life and maintain working efficiency. The IP67 protection offers good dust and splash protection during normal use, but avoid soaking the motor in water for extended periods as this can damage internal components.
• What vehicles are compatible with this motor? — The EZRUN 5690SD G2 is recommended for 1/6th short course trucks, general trucks, and 1/5th light-load truck applications. Specific vehicle examples include the Losi Super Baja Rey, ARRMA Kraton 8S, and ARRMA Outcast 8S. Before purchasing, confirm that your chassis is designed for 1/5th or 1/6th scale brushless motors and can accommodate the motor's dimensions (56mm diameter, 90.2mm length).
• How much does the EZRUN 5690SD G2 weigh, and will it fit my vehicle? — The motor weighs 867g (including power wires) and measures 56mm in diameter with a 90.2mm length. This is a substantial motor designed for larger scale vehicles. Always consult your vehicle's specifications to ensure it's designed for this motor size before purchasing. The 8mm shaft diameter is a standard size that should fit most compatible motor mounts.
