Good day,

My drone crashed over the weekend and need help with viewing the log of the flight. There were no interference or warnings on the app while I was flighting. The crash happened while RTL to home, it look like the drone stopped for a split second and just fall out off the sky. Its a 350mm size drone with Radiolink MiniPix V1.0ii Flight cantroller 4.0.3.

Thanks in advance.

Hello @Vida29er

It seems that the ESC or motor 2 was faulty. In the image you can see that the PWM of motor 2 went to max while motor 1 went to minimum to compensate.

Maybe a bad motor or ESC, a bad solder point or broken cable… have you seen some damage on those parts?

I will check every thing again, there were no damage after the crash that I have pick up. The drone has over 4h flight time.
