Key Features

• Intelligent Freewheeling Technology — The innovative freewheeling system in the ESC enables higher driving efficiency, significantly reduces operating temperature, and dramatically improves the overall stability and reliability of your RC power system, ensuring longer component lifespan and consistent performance.
• Powerful Built-in BEC (Battery Eliminator Circuit) — With a continuous current output of 5A and maximum instantaneous output of 10A, the switch-mode BEC can power demanding high-torque servos with ease, whilst offering switchable voltage output between 6V and 7.4V to match your specific servo requirements.
• Massive 1640µF Built-in Capacitor — The super-large integrated capacitor eliminates the need for external capacitors on 10th scale models, simplifying your installation, reducing wiring complexity, and improving ease of use without compromising any performance.
• Advanced Efficient Cooling System — An integrated radiator design combined with patented copper thermal conduction sinks on the internal power board rapidly conducts heat from critical components to the heatsink, whilst an active cooling fan dissipates heat efficiently, keeping your ESC operating in optimal thermal conditions even during intense driving sessions.
• Capacitor Thermal Protection — Built-in thermal protection prevents capacitors from overheating and exploding under load, providing irreplaceable safeguards against catastrophic failure and extending the lifespan of your electronics.
• IP-67 Waterproof and Dustproof Rating — This professional-grade weatherproofing allows your RC truck to operate in mud, sand, ice, snow, and water without damage to the power system, making it perfect for all-weather RC driving in the UK and beyond.
• High-Efficiency 3660SL Motor with 3700KV Rating — The brushless motor features a 10% power increase compared to equivalent competitors and delivers 8% higher efficiency with significantly lower operating temperatures, thanks to its precision engineering and high-strength materials.
• Explosion-Proof Rotor Design — Front and rear aluminium end plates improve overall balance and durability, whilst the rotor is wound with high-strength tensile materials to provide excellent explosion-proof capability and long-term reliability.
• Modular Detachable Design — The motor's detachable construction allows for easy cleaning and routine maintenance, effectively extending service life and maintaining working efficiency between races and bashing sessions.
• Programmable via LCD Program Box — Configure your ESC settings using the optional LCD Program Box (sold separately), allowing you to fine-tune performance parameters and adjust the ESC behaviour to suit different driving conditions and personal preferences.
• Multiple Protection Functions — Battery low voltage protection, ESC overheat protection, throttle signal loss protection, current protection, and capacitor overheat protection work together to safeguard your equipment and prevent damage.
• Independent Programming Port — The dedicated programming port means you don't need to disconnect servo wires when programming the ESC, making setup and adjustments much more convenient.

Technical Performance

This power combo represents the pinnacle of 1/10th scale brushless RC engineering. The QuicRun WP 10BL120 G2 ESC delivers an impressive 120A continuous current with peak bursts up to 760A, providing more than enough power for aggressive acceleration and sustained high-speed runs on your 1/10 scale monster truck or short course truck. The ESC accepts 2S to 4S LiPo batteries, offering tremendous flexibility in your battery selection and allowing you to choose between lightweight 2S setups for lighter trucks or higher-voltage 3S and 4S packs for maximum performance. The switch-mode BEC operates across 5-7.4V input voltage and delivers clean, regulated power to your receiver and servos with impressive efficiency. Measuring just 52.8×39.8×38.2mm and weighing 119g including connectors, the ESC is compact enough to fit easily into most 1/10th scale chassis whilst providing professional-grade cooling and protection. The XT60 connector input and 4.0mm gold-plated female output connectors ensure reliable power delivery without voltage drop. The integrated 25×25×10mm framed cooling fan maintains optimal thermal management during extended runs, with the entire assembly powered by the onboard BEC so there are no additional fan connectors to worry about.

The matched 3660SL brushless motor features a 3700KV rating specifically tuned for excellent performance in 1/10th scale trucks, delivering explosive power and smooth acceleration across the entire throttle range. With a 4-pole design and measuring 36mm in diameter by 60mm in length, this motor produces 273g of rotating mass with 5mm shaft diameter for direct compatibility with standard 1/10 scale drivetrain components. The motor operates efficiently on 2S or 3S LiPo batteries, with a no-load current draw of just 6.5A, ensuring low idle current and extended battery runtime. Premium ball bearings front and rear (D16×D5×T4) ensure smooth, reliable operation through thousands of run cycles. The entire brushless power system is waterproof-rated to IP-67 standards, meaning both the ESC and motor can handle wet conditions, splashes, and muddy terrain without performance degradation or damage to critical electronics.

Frequently Asked Questions

• Is this combo suitable for beginners? — Yes, this is an excellent choice for beginners stepping up to brushless power systems. The factory-matched combo eliminates compatibility guesswork, the waterproof design allows forgiving outdoor driving, and the simple XT60 connectors and 4.0mm motor plugs are industry-standard. However, you should be comfortable with basic RC maintenance and understand LiPo battery safety before operating this equipment.
• What battery does this need? — This combo accepts 2S, 3S or 4S LiPo batteries. A 2S 5000-7000mAh battery provides good runtime with lower power and cooler running temperatures, ideal for beginners or lighter trucks. A 3S battery delivers significantly more power and speed, whilst 4S packs provide maximum performance for competitive driving. Always choose a battery with matching voltage and appropriate discharge rating for your truck's weight and drivetrain.
• Can I run this power system in wet conditions? — Yes, the IP-67 waterproof rating means the ESC and motor can handle splashes, mud, rain, and water crossings without damage. However, this rating is for splash and water resistance under normal use—it is not designed for prolonged submersion or soaking. Rinse and dry your equipment after wet driving to maintain protection levels.
• What is the difference between this 3700KV motor and lower KV options? — KV rating determines how many RPM the motor spins per volt. A 3700KV motor spins faster and produces higher top speed compared to lower KV ratings like 3150KV or 3250KV, but sacrifices slightly lower torque. The 3700KV in this combo is optimised for 1/10th scale trucks on 2S or 3S batteries, providing an excellent balance of speed and acceleration.
• Do I need a program box to use this ESC? — No, the ESC works right out of the box with default settings suitable for most applications. However, an optional LCD Program Box allows you to customise features like throttle curve, rotation direction, BEC voltage output, and other parameters to fine-tune performance for your specific truck and driving style.
• Is this ESC compatible with my radio system? — The QuicRun WP 10BL120 G2 ESC is compatible with standard RC receivers from any major brand (Spektrum, FrSky, Futaba, etc.). Simply connect the throttle signal wire from your receiver to the ESC's signal input and you're ready to go. No brand-specific compatibility issues.
• What makes the G2 version better than earlier QuicRun models? — The G2 generation introduces intelligent freewheeling technology that improves efficiency, reduces operating temperature, and enhances overall stability. The larger 1640µF built-in capacitor eliminates external capacitors, whilst the advanced cooling system with active fan management ensures the ESC stays cool during intense driving sessions.
• Can I upgrade the connectors on this ESC? — The combo ships with XT60 battery connectors and 4.0mm gold-plated motor connectors. Many retailers offer connector installation services if you prefer EC3, Deans, EC5, XT-90, or IC-series connectors, though the included connectors are industry-standard and fully reliable.
