As you know, the yaw axis will be not working anymore on ICM20689 gyrometer some times. Listening to pilot's feedback, working with the developer on Betaflight, contacting with the FAE on TDK. But until now, not solved. So we update the gyro to BOSH BMI270 since V2.2 version. Also, all the Betaflight FC boards will update the gyrometer to BOSH BMI270 or TDK ICM42688 following.

Pay attention, ONLY the newest Betaflight firmware 4.3.1 start to support this BMI270 gyrometer or ICM42688. Please check the below link to download the firmware.

Download the FC firmware betaflight_4.3.1_BETAFPVF4SX1280.hex

Note: If your FC board has the yaw axis issue unfortunately, please feel free to email support@betafpv.com for a replacement. Order list and a short video for this issue would be appreciated.

The BLHeli_S firmware could support the BB51 hardware now. This V2.2 board is powered by BB51 hardware. If you want to setup the ESC specification, please update to the newest BLHeliSuite-16714902a first.

Download the newest BLHeliSuite-16714902a here.
