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.

Download the BB51 ESC firmware C_X_30_REV16_7_20220802.hex

Note: BetaFlight Configurator, BLHeli Configurator, Bluejay Configurator are invalid for the BB51 ESC now.

FAQ

• ExpressLRS 2.4G is the most popular radio link now. Know more about ExpressLRS here.
• Please DO NOT change the ESC or Motor settings on Betaflight configurator, BLHeli Configurator, or Bluejay Configurator, otherwise, the FC will be invalid. Please download and run the latest BLHeliSuite-16714902a for setup.
• The frame and props are visible when the camera's angle is 0°. Adjust it to about 25°, then the frame and props are invisible when flying.

• Click to download the Manual for Cetus X Brushless Quadcopter.
• Cetus X Brushless Quadcopter should work with two 1S batteries. Do not recommend using different brand batteries. Highly recommend the original batteries BT2.0 450mAh 1S 30C Battery.
• Cetus X Brushless Quadcopter is similar to Meteor85 Brushless Whoop Quadcopter (2S) in many ways. For flying maneuverability and more battery choices, Meteor85 is a good alternative choice.
