Features

● EFM8BB21F16G MCU, pipelined 8-bit C8051 core with 50 MHz maximum operating frequency.

● Dedicated high frequency driver, makes the start more smooth. ESC maximum speed is limited to 500k eRPM.

● Two layers tower structure between 4in1 ESC and FC using quick pin connection. Dual ways signal transmission makes the 

 flight more stable 

● Exposed pads for Battery and Motor wires, fast welding without additional disassembly, makes the installation faster and 

 more convenient. 

● F3 flight controller, supports PPM, PWM and SBUS remote control / receiving mode.

● FC integrated OSD, also integrated 5V/1A, 12V/500mA for VTX, camera, buzzer, LED and other peripheral devices ; 

 provided several silicone cables for connectors on FC ,and will give you an unprecedented experience for installation;

● Built-in current meter, OSD directly display the real-time current without any additional connection;

● BLHeli-S firmware. It designed for superior performance in multirotors, and uses hardware generated motor pwm for smooth 

 throttle response and silent operation. 

● The code supports regular 1-2ms pulse width input, as well as Oneshot125 , Oneshot42 and Multishot . 

● Supports Dshot150, Dshot300 and Dshot600.Dshot is digital signal, anti-interference ability is stronger, and do not need throttle calibration.
