After upgrading the firmware of HAKRC F7220 AIO, the sensor direction needs to be changed

1. Connect FC to BF and select “configuration” page.

2. In the “flight control and sensor direction” column on the right side of the configuration page, change the first gyroscope to cw 90

3. on the setup page. Calibrate the flight control accelerometer and reset the z-axis and test whether the flight control roll, pitch and yaw are consistent with the BF feedback direction.

4. please check and make safety preparations before takeoff in an open or relatively safe place to test the flight feasibility.

5. If you use the DJI remote control and the DJI FPV glasses, open the serial data receiver Port 2 and MSP Port 6, as shown below:


  • The PCB adopts high-end 8-layer 2oz thick copper skin, which has stronger over-current capability and good heat dissipation
