Key Features

• Asymmetrical Ball Bearing Design — The motor uses different sized ball bearings at the front and rear, with a large precision bearing at the front for superior load-carrying capacity and a smaller bearing with lower resistance at the rear. This asymmetrical configuration increases both reliability and overall efficiency, meaning your motor will handle the stresses of aggressive driving whilst maintaining smooth operation and longevity.
• Ultra-High Efficiency with Reduced Temperature Rise — Through careful engineering and refinement, this motor achieves exceptional efficiency levels, resulting in minimal heat generation during operation. With internal temperatures approximately 20°C lower and external temperatures around 12°C lower than equivalent motors under identical test conditions, you'll experience extended runtime and reduced thermal stress on your ESC and battery.
• Precisely Balanced Rotor — The rotor is carefully balanced to eliminate vibration and energy loss, ensuring smooth operation across the entire power band. This precise balance delivers good linearity in throttle response and prevents the energy wasting vibrations that can reduce overall performance and create unwanted mechanical stress on your vehicle's drivetrain.
• 10AWG Silicone Outlet Wiring — The motor comes equipped with three 10AWG silicone wires that are flexible and easy to work with, unlike traditional rigid enamelled wire. The silicone construction makes wiring your motor to your ESC simple and straightforward, whilst the aesthetic appearance looks far more professional than older cable types, and the low-resistance connectors ensure efficient power transfer.
• 6.5mm Male Connector (Low IR) — The standard 6.5mm male connector fitted to this motor ensures plug-and-play compatibility with modern brushless ESCs, including the Hobbywing WP 8BL150 G2. The low internal resistance design minimises voltage drop and maximises power delivery to your motor, ensuring every amp from your battery translates into rotational force.
• Blind Hole Thread Design — The front mounting features a blind hole thread design that prevents damage from over-long mounting screws whilst maintaining compatibility with both M3 and M4 fasteners. This thoughtful engineering means you can adapt the motor to various mounting requirements across different vehicle platforms without worrying about screws protruding through and damaging the motor internals.
• Modular Structure Design — The motor's modular construction makes disassembly, cleaning, and maintenance straightforward for hobbyists who want to keep their equipment in peak condition. Regular maintenance is convenient and quick, effectively prolonging the motor's working life and maintaining its efficiency over extended use.
• Solid Materials and Quality Construction — Hobbywing's manufacturing process and commitment to high-quality materials ensures this motor delivers exceptional durability, maximum performance, and consistency across every unit produced. You're buying genuine engineering excellence, not a cheap knockoff.
• Maximum RPM Rating of 55,000 — With a 2000KV rating on a 6S LiPo battery system, this motor can safely operate at up to 55,000 RPM, providing the power needed for thrilling acceleration and top-end speed in 1/8 scale applications without compromising reliability.

Technical Performance

The QUICRUN 4274SL G2 is engineered as a brushless sensorless motor specifically optimised for 1/8 scale Monster Trucks and similar applications. With a 2000KV rating, this motor delivers responsive throttle characteristics across 3S to 6S LiPo battery configurations, making it versatile for various power levels depending on your ESC and battery choice. The motor's 42mm diameter and 74.9mm length represent the industry-standard size for 1/8 scale applications, with a 5mm shaft diameter that mates to standard pinions. At just 477 grams, the weight is competitive for this class of motor, keeping your vehicle's centre of gravity low and improving handling characteristics.

The no-load current draw of 5.9A indicates efficient operation and low internal resistance — a sign of quality winding and construction. This efficiency is crucial for maximising battery runtime and minimising heat generation during extended driving sessions. The motor uses a 4-pole configuration and sensorless design, meaning it integrates seamlessly with sensorless ESCs like the recommended WP 8BL150 G2, eliminating the need for complex sensor wiring whilst still delivering smooth, reliable commutation across the entire RPM range.

The asymmetrical bearing arrangement is particularly clever engineering: the front bearing (D16×D5×T5) handles the radial loads created by the pinion gear meshing with your vehicle's spur gear, whilst the rear bearing (D13×D5×T4) uses a smaller diameter to reduce friction in the non-load-bearing end. This design philosophy permeates Hobbywing's engineering approach — every component choice is made to optimise the specific function it performs. Built with precision tolerances and quality materials throughout, this motor will withstand the impacts, vibrations, and sustained high-rpm operation that characterises serious RC truck driving in the UK.
