Hey All,
i had a fatal crash a month ago (maybe a voltage problem). I rebuilt the quad with new engines and everything from the scratch. Today i flew 6 batteries and everything was really good. On the last (almost fresh) pack the quad suddenly fell from the sky. Again on a paved road so it got destroyed again. Can anyone please tell what happened from the logs? I really need to find out what happened because i cannot afford a fatal crash any month. I am almost about to give this all up although i really love it ...
thanks!

you fly X frame, and pitch and roll rarted to oscillate in sync.
It seems like you got a problem with motor/propeller #1 (front right) - APM was struggling with keeping that side up, giving very much throttle.
Most likely a slipping prop.
Hey Andre,
thank you very much- this helps me a lot. Would you please explain me where you found this? I can see Mot 2, Mot 3 and Mot 4 doing something very different from Mot1 (In the »mot«) panel. Is this the place i have to look for it or did you find this somewhere else?
once again - thank you ...
André
If you plot ATT/Pitch and ATT/Roll, you'll see then it started to oscillate synchronously,
The parameter FRAME=1 says you have a X config. - when both axis oscillate the same, it must be a problem with one of two motors. (on a + frame, one motor would mainly influence one axis)
Then you see MOT/Mot1 - that worked using normal thrust all the time, but at the end, it needed to go much higher to to keep it level. That's a sure sign of trouble.
