Review on 💥 iFlight SucceX-D F4 Flight Controller + 20A ESC AIO Whoop Board (MPU6000) - Optimized for Tiny Whoop Cinewhoop FPV Racing Drone Quadcopter, Compatible with FPV Air Unit by Renee Cook

and connect it to Betaflight. Yaw was not working on the settings page. All axes that worked moved in slow motion. The MPU6000 gyroscope was bad. I tried installing it anyway and the flight control board part just happened to be talking to the ESC board part. Sometimes there were 5 beeps when connecting the battery. Sometimes there were only 3 beeps. I don't know if this brand is or not because all brands are from China. All brands use the same components. I received more new air traffic controllers with defective gyros or defective F4 chips than working air traffic controllers. The seller refunded me the money immediately, so the seller is well done. The product just didn't work.
