About the Brushless Combo
Compact ESC With Advanced Efficiency
The Quicrun 12BL45 G2 ESC utilizes intelligent freewheeling technology to improve drive efficiency while reducing operating temperatures. This advanced control system helps maintain stable performance and smooth throttle response even during demanding runs. The redesigned housing is more compact than previous generations, making it easier to install in tight chassis layouts and simplifying wire management. This combination of size and performance makes the ESC a versatile solution for small-scale vehicles.
Upgraded BEC For Modern Servos
The built-in BEC has been significantly upgraded to deliver 2A continuous current and up to 4A peak output, providing reliable power for modern high-torque servos. The selectable output voltage of 6V or 7.4V allows drivers to match the ESC to their servo requirements for faster response and improved steering precision. This enhanced power delivery ensures consistent control and responsiveness during aggressive driving. The result is smoother handling and improved driving confidence.
Durable Motor For Demanding Conditions
The included 2840SL G2 brushless motor is designed with durability and efficiency in mind. High-quality materials such as 0.2mm silicon steel laminations, high-temperature resistant enameled wire, and precision bearings help ensure long-lasting operation. The motor’s IP56 rating offers protection from dust and moisture, making it well suited for off-road vehicles operating in harsh environments. Pre-soldered gold-plated 3.5mm connectors provide convenient plug-and-play installation while maintaining excellent electrical conductivity.
