Features: Upgraded 32-bit M4 microprocessor with more powerful processing capability guarantees stable control and rapid response. (Industry's highest 32-bit microprocessor, increased processing speed by X4) Peak current up to 1200A. (this is not a typo) Built-in switch mode BEC with a maximum output of 10A and voltage adjustable from 5V to 7.4V (step: 0.1V) for usage with servos & other devices require different voltages. Variable frequency regulation of PWM & brake frequencies allows users to precisely regulate the driving; braking forces (of the motors). Expanded range of the max. brake force brings in the active brake ranges from 101% to 150%. Softening function (HOBBYWING-initiated) for milder or wilder driving control and better driving efficiency. 10 select-to-use profiles applicable to all 1/10th RC car racing. Internal electronic key switch for long service life, high reliability; and the external switch port for connecting an external switch (included in the product box) is applicable to different situations. Separate PRG/FAN port is able to power an external fan for maximize cooling performance or connect a LCD program box or WiFi module to the ESC. With the WIFI express module (purchase separately), users are able to program parameters, upgrade firmware and check relevant data during the event using either the iPhone or Android devices. Switchable motor direction (CCW/CW) for various chassis.
