Technical Performance

The QUICRUN 3660SL G2 is engineered to deliver outstanding performance with its 3150KV rating and 4-pole brushless sensorless configuration. At just 273 grams, this motor offers an excellent power-to-weight ratio that makes it ideal for 1/10 scale RC trucks and monster trucks. The motor measures 36mm in diameter with a 60mm length, featuring a standard 5mm shaft diameter compatible with most 1/10 scale drivetrain components available to UK RC enthusiasts. The no-load current of 5.4A ensures efficient operation and minimal heat generation when the motor is spinning without load, contributing to the motor's excellent thermal characteristics. The front and rear bearings are precisely sized at D16×D5×T4, providing smooth, low-friction operation that maximises efficiency and responsiveness. This brushless motor is optimised for 2-3S LiPo battery systems, making it compatible with the most popular battery configurations used in 1/10 scale RC vehicles throughout the UK. The combination of premium materials—high-hardness aluminium construction, CNC-machined end covers and ultra-thin low-loss silicon steel sheets—ensures consistent performance and durability. The 200°C high-temperature-resistant enamelled wire allows the motor to handle sustained high-power operations without degradation, whilst the explosion-proof rotor design with reinforced aluminium end plates provides structural integrity that rivals or exceeds motors at significantly higher price points. Whether you're upgrading an existing RC car or building a new brushless RC setup, the QUICRUN 3660SL G2 delivers the performance, reliability and efficiency expected from Hobbywing's flagship motor series.

Frequently Asked Questions

• What is the difference between the QUICRUN 3660SL G2 and earlier generation QUICRUN motors? — The G2 (Generation 2) represents the latest advancement in Hobbywing's motor technology, featuring a 10% increase in maximum output power and 8% improvement in motor efficiency compared to previous specifications. The G2 also operates noticeably cooler under load, thanks to advanced engineering and superior materials including the explosion-proof rotor design and premium bearings. This makes the G2 generation the superior choice for modern 1/10 scale RC applications.
• Is the QUICRUN 3660SL G2 suitable for beginners? — Yes, absolutely. Whilst this is a performance-oriented motor suitable for experienced users, its reliable sensorless brushless design, straightforward installation and compatibility with standard 2-3S LiPo batteries make it accessible to RC enthusiasts at all levels. The modular detachable design also makes maintenance straightforward for beginners learning to service their own equipment.
• What battery does the QUICRUN 3660SL 3150KV need? — This motor is optimised for 2-3S LiPo battery packs, which are the most popular battery option for 1/10 scale RC vehicles in the UK. The 3150KV rating provides an excellent balance of speed and torque across this voltage range, making it compatible with standard LiPo packs ranging from 2S (7.4V nominal) to 3S (11.1V nominal).
• Will this motor work with my existing 1/10 scale RC truck? — The QUICRUN 3660SL G2 is designed as a drop-in replacement for most 1/10 scale RC trucks and monster trucks, featuring a standard 5mm shaft diameter and compatible bearing sizes. However, you'll need to ensure your chassis features a compatible motor mount and that your ESC and battery system support brushless motors. Check your vehicle's specifications before purchase.
• How does the no-load current of 5.4A affect performance? — The 5.4A no-load current is an excellent specification that indicates minimal internal friction losses and efficient operation. This low no-load current means the motor spins freely with minimal resistance, contributing to the motor's high efficiency rating and cooler operating temperatures compared to competing motors.
• Is the modular detachable design really easier to maintain? — Yes, significantly. The modular design allows you to easily disassemble the motor for cleaning and inspection without requiring special tools. This is particularly valuable for users who frequently race or bash their RC vehicles in dusty or muddy conditions, as regular cleaning helps maintain peak performance and extends the motor's lifespan.
