Skystars F7+KO60 is a powerful stack for freestyle and racing drones. The flight controller with modern F7 processor has 16MB of blackbox memory and 5V/3A and 10V/3A BEC. The FC has a connector for DJI FPV system. OSD chip is also present so it can be conveniently used on a drone with both digital and analog video transmission. The pads for connecting the LEDs in the corners of the controller are also nice. The integrated barometer for altitude measurement also comes in handy.

The KO60 ESC uses 32-bit BlHeli_32 firmware, which supports bidirectional dshot, telemetry, high PWM frequency and other advanced features. The ESC is based on a 6 layer PCB with 3oz thick copper. This allows the ESC to convert even high currents. Large 5x6mm 40V Toshiba Mosfets are used. For better cooling, the ESC is equipped with an aluminum heat sink. Also included is a capacitor that needs to be connected to the battery leads on the ESC.
