• Comprehensive Multi-Level Protection System — Built-in protection functions include battery low voltage detection, ESC overheat protection, throttle signal loss protection, and overload protection, ensuring your equipment stays safe during use.
• Adjustable Motor Rotation Direction — Motor rotation is selectable between clockwise (CW) and counter-clockwise (CCW), allowing you to adapt the ESC to different chassis configurations and mounting orientations without additional hardware.
• Firmware Upgrade Support — The ESC supports firmware updates when used with the Multifunction LCD Programming Box Pro, ensuring you always have access to the latest features and improvements from Hobbywing.
• Heavy-Duty Wiring and Connectors — Supplied with high-capacity 12AWG wiring in black and red for battery input (200mm length) and blue, yellow, and orange for motor output (200mm length), providing reliable power distribution without voltage drop.

Technical Performance

The QuicRun 10BL120 G2 represents the pinnacle of entry-to-intermediate level ESC design, delivering 120A continuous current with an impressive 760A peak current rating—making it powerful enough for serious competitive racing whilst remaining accessible to hobbyists. Built on Hobbywing's proven platform, the ESC combines top-tier hardware with sophisticated firmware to create a robust and reliable solution. The voltage range of 5-8.4V supports both 2S and 3S LiPo battery configurations, with motor compatibility starting at 4.5T for 2S systems and 10.5T for 3S systems using standard 3650-size brushless motors. The BEC's switch-mode design ensures efficient power conversion with minimal heat generation, whilst the 6V/7.4V adjustable output at 4A continuous (7A peak) provides ample power for modern high-torque servos. The compact framed fan design, measuring 25 × 25 × 10mm, provides active cooling to maintain optimal operating temperatures during extended driving sessions. Weighing just 101.5 grammes (including wires and connectors), the QuicRun 10BL120 G2 adds minimal weight to your RC car whilst maximising performance. The engineering is focused on reliability with multi-layer protection against battery under-voltage, thermal overload, signal loss, and mechanical overload—critical safeguards for protecting your investment in brushless RC car UK systems.

Frequently Asked Questions

• Is the Hobbywing QuicRun 10BL120 G2 suitable for beginners learning to drive RC cars? — Yes, absolutely. This ESC was specifically designed with beginners and intermediate modellers in mind. The straightforward programming via the on-board SET button makes initial setup very simple, whilst the comprehensive protection systems keep your equipment safe as you learn. The dual sensored/sensorless modes also give you flexibility to find the control feel that suits you best.
• What battery does the QuicRun 10BL120 G2 need, and what's the voltage range? — The ESC supports 2S and 3S LiPo batteries, operating in the voltage range of 5-8.4V. For 2S systems, use motors rated 4.5T or higher; for 3S systems, use motors rated 10.5T or higher. The ESC handles both configurations safely with built-in low voltage protection to prevent over-discharging your battery.
• Can I use high-torque servos with the QuicRun 10BL120 G2? — Yes, the upgraded BEC system delivers 4A continuous output (7A peak) at selectable 6V or 7.4V, which is sufficient for high-voltage, high-torque servo systems currently available on the market. This is a significant improvement over earlier versions and gives you genuine servo control headroom.
• How do I programme the QuicRun 10BL120 G2? — You have multiple options: use the on-board SET button for basic configuration, pair it with an LED Programming Box for more detailed tuning, or use the Multifunction LCD Programming Box or LCD Programming Box Pro for comprehensive parameter adjustment and firmware updates.
