Featuring a 120A ESC with smart freewheeling technology, IP67 waterproof rating, and a powerful built-in BEC, this combo ensures smooth, reliable, and efficient operation across diverse terrains and conditions. Its advanced cooling system and comprehensive protection mechanisms make it a top-tier upgrade for competitive and hobby-grade RC vehicles. ## Description Excellent waterproof and dustproof performance, it is easy to deal with various climatic conditions and harsh environment. Smart freewheeling technology makes the esc have higher driving efficiency and lower operating temperature, and the stability and reliability of the esc are further improved. Built-in powerful switch mode BEC, continuous current up to 5A, instant up to 10A, and support 6V/7.4V adjustable, easy to drive various powerful and high-voltage steering servo. Multiple protection functions: battery low voltage protection, esc overheat protection, throttle signal loss protection, current protection, capacitor overheat protection. It has an independent programming port. When connecting the program card, it is not necessary to pull the throttle cable out of the receiver, which is more convenient to use. Review: Great 3s upgrade for new traxxas stampede / hoss - Worked great to convert my traxxas stampede / hoss from the BL2S system to 3s . The truck is wickedly fast now on 3s. I do recommend a heatsink/fan for the motor though. Review: Great Brushless Upgrade for FMS F100 - Amazing motor and esc combo!! This is my second hobbywing quickrun combo and both were east installs. This kit I put in my FMS F100 2wd RC truck as an upgrade from the stock brushed system. It's fast and runs smooth with no overheating issues. Things to know, 1. The motor shaft is 5mm so you will need a 5mm 32P pinion gear. I used a 14 tooth pinion as it's close to stock pinion size. The battery connection is an XT60, so be sure you have XT60 compatible batteries or pick up an adapter. ## Features - COMBO: QR10BL120 G2 ESC & 3660SL G2 Motor - Intelligent freewheeling technology, greatly improved performance The innovative intelligent freewheeling technology enables higher driving efficiency and lower operating temperature of the ESC, and further improves the stability and reliability of the ESC. - Powerful built-in BEC The ESC has a built-in BEC with a continuous current of 5A and supports a maximum output current of up to 10A. The output voltages are switchable between 6V, 7.4V. This ensures that the ESC is able to support the demanding high-torque servos in the market. - Efficent cooling system The integrated radiator design, combined with the patented copper thermal conduction sink on the internal power board of the ESC, facilitates the rapid conduction of internal heat to the radiator, and the fan is added to dissipate heat. These results an efficient heat dissipation system to ensure that the ESC is always in a good heat dissipation state - Capacitor Thermal Protection Capacitor thermal protection is designed and implemented into the ESC to effectively prevent capacitors from exploding and causing irreversible damages to the ESC due to overloading..High protection level, all-weather operation The IP-67 waterproof Rating guarantees excellent waterproof and dustproof protection. The whole power system is able to drive on a variety of surfaces including mud, sand, ice, snow and water without damaging the power unit. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0C6BFFB96 | | Best Sellers Rank | #42,829 in Toys ( See Top 100 in Toys ) #14 in RC Electric Speed Controllers | | Brand | Hobbywing | | Brand Name | Hobbywing | | Customer Reviews | 4.7 out of 5 stars 188 Reviews | | Included Components | (1) Quicrun 10bl120 G2 ESC, (1) Quicrun 3660SL Motor, (2) Manual | | Item Type Name | Brushless ESC and Motor Combo | | Item Weight | 522 g | | Item weight | 522 g | | Manufacturer | Hobbywing Technology | | Material | ESC: Plastic Housing | Aluminum Housing | PCB Motor: Steel and Aluminum | | Material Type | ESC: Plastic Housing | Aluminum Housing | PCB Motor: Steel and Aluminum | | Model | QuicRun WP 10BL120 G2 | | Model Name | Quicrun 10BL120 G2 & 3660SL G2 COMBO | | Model name | Quicrun 10BL120 G2 & 3660SL G2 COMBO | | Number of Items | 3 | | Part Number | 38030210 | 38030211 | | UPC | 088718520195 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** HOBBYWING - **Item weight:** 522 g - **Manufacturer:** Hobbywing Technology - **Material:** ESC: Plastic Housing | Aluminum Housing | PCB Motor: Steel and Aluminum - **Model name:** Quicrun 10BL120 G2 & 3660SL G2 COMBO ## Images ![HOBBYWING Quicrun 10BL120 G2 & 3660SL G2 Combo (QR10BL120 + 3660-3700KV SL G2 Combo) - Image 1](https://m.media-amazon.com/images/I/51B+8bh0QGL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great 3s upgrade for new traxxas stampede / hoss *by M***A on 19 August 2024* Worked great to convert my traxxas stampede / hoss from the BL2S system to 3s .
