Zero timing firmware for roar SPORTMAN races and other fair races. World's smallest footprint & lightweight ESC ever. "23.5G" programming/upgrading/ data reading wirelessly: integrated data logger can record the maximum temperature of ESC and motor as well as the maximum RPM. Built-in boost BEC with a maximum output of 6A and voltage adjustable between 6V and 7.4V for usage with high voltage servos. Separate program/fan port is able to power an external fan for maximize cooling performance or connect a LCD program box or Wi-Fi module to the ESC. With HobbyWing Wi-Fi express module, users are able to program parameters, upgrade firmware and check relevant data during the event using either the iPhone or Android devices. New brakes and throttle functions: 100 levels of brag brake, 50 levels of initial brake force, 9 levels of maximum brake force, 20 levels of brake Rate, and 30 levels of throttle Rate. Adjustable brake mode, PWM and brake frequencies and for different competitions and control feel. Adjustable turbo timing & boost timing for different applications. Multiple protections: low-voltage cutoff protection, ESC and motor thermal protection, and fail safe (throttle signal loss protection). data logging for recording the maximum ESC/motor temperature, motor speed/RPM, and others in real time.
