Hi all
I have built a drone with 420 Lite ESCs and dji E series motor. My FC is F4SD.
After following tutorials on betaflight, my drone seems to flip upon takeoff.
Upon inspection, it seems that the motors are not in sync.
At 25% throttle, some motors would be at 60% speed, whilst at 50% throttle, some motors would be at a 100% speed while others would just barely turn on.
What seems to be the issue here? I have replaced all components.
For inspection, a 12Vdc power generator is used, so there should be no power issues.
