The hobbywing ezrun max8 g2s brushless esc and 4268sd g2r brushless motor combo are engineered to deliver peak performance in 1/8 scale applications. This heavy hitting combo features the optimized g2r brushless motor, which offers maximum torque and increased power with lower internal resistance, ensures efficient and cooler operation. This combo is designed to maximize your potential with unmatched performance and reliability. About the combo technology the ota programmer allows for real-time data recording, enabling you to monitor throttle, voltage, current, temperature, motor rpm, and more. This data can be viewed in real time and recorded using hw link for easy data analysis. The system includes multiple protections such as low-voltage cutoff, esc and motor thermal protection, fail-safe (throttle signal loss protection), and reverse polarity protection. Firmware upgrades are possible via the hobbywing multifunction lcd pro program box or the ota programmer (both sold separately). Motor the hobbywing ezrun 4268sd g2r sensored brushless motor has been designed to provide maximum speed and power. Using an advanced sensored system, this motor can deliver more aggressive launches, higher speeds and better efficiencies. With the waterproof sensor connection, you can enjoy all the benefits of a sensored system no matter the terrain. Esc the esc features three built-in 680uf capacitors, enhancing performance by 74% (870uf) compared to the max8 esc. These large capacitors eliminate the need for external capacitors on your vehicle. It also includes a patented frameless fan design, which rapidly transfers internal heat to the integrated housing radiator. High airflow from the fan's side and a copper thermal conduction sink on the internal power plate ensure efficient cooling. This design maintains the esc's reliability and optimal thermal condition. Features motor advanced sensored brushless technology ensures precise control and smooth power delivery the fully closed case design effectively keeps dust and debris out, protecting the internal components the waterproof sensored motor is built to withstand wet conditions, allowing for reliable operation in most environments designed for extreme speed and power, this motor is engineered to deliver exceptional acceleration and top-end speed esc enhanced waterproof and dust-proof design for various climates. Built-in 6a/15a switch mode bec, supports 6v/7. 4v/8. 4v servos. Advanced electronic switches prevent dust, humidity, and impact issues. 32-degree turbo timing increases rpm by 25% with compatible motors. Real-time data logging and firmware updates via hw link app and bluetooth.
