How To Fix Desync In 59 Seconds？
Introduction: FPV desync happens when an ESC loses sync with its motor, causing the motor to stall or cut out mid-flight. To fix it: inspect your hardware, add a low-ESR capacitor, and tune BLHeli & Betaflight settings like rampup power, demag compensation, and motor idle to stabilize your system. What is Desync Issue? FPV desync (ESC desync) occurs when the Electronic Speed Controller (ESC) fails to keep up with the motor’s commutation timing. Once the ESC loses track of the motor’s position, the motor stalls and your drone can violently spin (death roll) and crash. Typical signs of FPV motor desync: Sudden flip or roll mid-air (usually just one motor stops) Stuttering noise from one motor Blackbox logs showing a motor command hitting 100% while thrust drops For example： Sometimes in flying, when you push the throttle and do some action, one of your motors will stop spinning, and then most likely you will crash. When reviewing the black box data, you may find the control signal curve for the motor increases rapidly to 100%. However, the gyroscope records indicate that the aircraft's attitude did not respond as expected to this motor speed increase; instead, it suddenly dropped to zero. Pro…
