Skystars F7 + KO60 is a powerful stack for freestyle and racing drones. The flight controller with a modern F7 processor has 8MB of memory for a blackbox and 5V / 3A and 10V / 3A BEC. The FC also has a connector for connecting DJI FPV and OSD, so it can be conveniently used on drones with digital or analog video transmission. The pads for connecting LEDs in the corners of the unit are also nice. The FC has integrated barometer for altitude measurement. It is supplemented by a 60A controller with BlHeli_32 firmware.
