Despite its compact dimensions of 36×30×15.5mm, the ESC delivers high-performance output of 4S/80A. It features strong low-speed torque, low startup speed, and smooth operation, making it an ideal power choice for 1/10th scale crawling. The ESC supports AUX channel control of drag brake force. By connecting the AUX input signal wire to an available channel on the remote control, you can adjust the drag brake power as you drive from your remote control. The integrated high-voltage BEC provides up to 11A of output current, with selectable output voltages of 6V/ 7.4V/ 8.4V. It easily powers high-torque, high-voltage servos, meeting a wide range of demands. The ESC is compatible with both Brushless and Brushed motors. The ESC includes mounting holes for a cooling fan to be installed. Builders can choose whether to install the fan to ensure the ESC operates within the ideal temperature range (around 60℃ on the case). The ESC comes equipped with integrated 3.5mm female connectors on the output side, enabling seamless connection to HOBBYWING motors or other motors with compatible plugs. No soldering is needed. The ESC's protection rated IP67, offering outstanding waterproof and dustproof performance. It can be used in muddy, sandy, icy, snowy, or wet terrain under various weather conditions without concern. NOTE: The IP67 rating provides protection against splashes, water exposure, and dust under normal use but is not permanent. Protective performance may degrade over time due to agin. Do not submerge the product for extended periods, as this may cause damage.
