The EzRun Max10 140A G2 features an improved waterproof sensored cable interface and an upgraded sensored mode to achieve a great sense of control feel and perfectly matches the EzRun 36523665 SD G3 motors.. Supports Turbo timing adjustment of up to 32 degrees, and in combination with the EzRun 36523665 G3, the maximum speed is 25 more with greater effect.. The smart start-stop technology is introduced to the Max10 G2 ESC. The frameless fan will not be enabled to reduced noise and saving power. The fan will only work when the temperature rises to a certain level.. Compared with the previous generation of the MAX10 ESC, the total capacitance of the capacitor is increased by 74 and is overheating protected. The functions improve the power delivery from the battery to the ESC to avoid it from overloading and causing capacitors to explode.. Smart freewheeling technology enables the MAX10 G2 to have higher drive efficiency than the previous generation, resulting in lower operating temperatures and a minimum temperature of approximately 25C lower than the previous generation.. After connecting the ESC with the OTA Bluetooth module, you can view the data throttle amount, voltage, current, temperature, speed and etc in real time through the mobile app to know the running status The history of the running status can also be viewed by data logging.. The IP-67 waterproof system guarantees excellent waterproofing and dustproofing 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..

Motor Limit With 3S Lipo KV 4000 3660 size motor With 4S Lipo KV 2600 4268 size motor. Built-in capacitor Super large built-in capacitor, The built-in capacitor of the ESC is as high as 1640uF. External capacitors are not needed for 10th scale models on the market and helps improves ease of use Size Weight52.8L x 39.8W x 38.2Hmm 119g Included wiresconnectors. 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.. Efficient 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..
