Skystars F7 Pro3 Wifi + KO50 BLS

The Skystars F7 Pro3 Wifi + KO50 is a combination of a flight controller with a modern F7 processor and a 50A ESC with BlHeli_S firmware. The stack is suitable for 5-6" freestyle drones. The flight controller has an integrated Wifi module so you can set it up wirelessly via your phone via Speedybee app.

The FC uses a BMI270 gyro, has 16MB of memory for blackbox, integrated barometer and 5V/3A and 10V/3A BEC. The FC also has a connector for DJI FPV and OSD connection, 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 FC are also nice. Power to the VTX can be switched off/on via the FC via a switch on the RC transmitter. This comes in handy if you are waiting for GPS satellites and don't want the video transmitter to heat up unnecessarily. 

The ESC is equipped with a TVS diode to filter out voltage spikes. It supports current up to 50A and power from 3-6S Lipo batteries. There is an aluminum heat sink on the ESC to help dissipate heat and protect the electronics from dirt. The ESC uses BlHeli_S firmware.
