The new SpeedyBee BL32 32bit 50A 3-6S 30x30 4in1 ESC comes packed with extras. The ESC is built with TVS protective diode to absorb the voltage spike when you plug in the battery, or during crashes that block your props. It also provides a humongous 1500uF low ESR capacitor, ensuring clean data from the gyro to the FC and tested by 2 top racing pilots, both over 1500 packs. It's also fitted with a high-quality CNC heat sink shield to significantly reduce the heat from your MOSFETs ensuring stable current flow at a high-throttle position. This ESC should have no issues with overheating. A great benefit in a stylish blue finish.
