Z axis vibrations --> altitude issues. Looking for evidence to link these in log

HiI had a frightening occurrence today where my 250-sized pixhawk / 3.2 quad suddenly started behaving very erratically in loiter mode -- rapidly gaining altitude.After spending some time graphing…Continue

"Paul do you possibly have something connected to (supplying power to) USB port on the pixhawk?   Battery failsafe won't trigger if the USB is connected. "

"Well, three props were off the craft after the crash.   Two had broken posts on the prop adapter, and one was just removed from an intact post, spinner nut and prop on the ground nearby and undamaged.  Prop adapter post was not bent.…"

"Thanks Rob.   I'm accepting at this point that a loose spinner nut was probably the culprit Scott'"

Scott Reid replied to Randy's discussion Copter-3.3 beta testing
"Thanks guys; I think the most likely explanation at this point is a loose spinner nut, not software. One of the props that was off after the crash had an intact adapter, spinner nut also intact but detached.  I initially attributed this to the…"

"Interesting.. I didn't notice the GPS glitch.   It was during a time when I was in loiter, quite a while before the crash.   It was basically one record with HDOP=99.99 (the lat/long/nsats were all normal) I've sort of come to…"

"I don't know if this was the cause of your crash, but there was a GPS fail. The interesting part is INAVErr jumped way up during that same period. Although in Stab mode, if Super Simple mode was on, it uses GPS.  I didn't look at much…"

Log analysis help - HW issue or PWM baseline/config issue?

Hi all - I'm having a little trouble determining exactly what happened here.    I was doing some initial backyard low-altitude hover testing of my new Y6B.   This is a large 750 size sky-hero frame with 6S batts.Around log line 113630, one arm dropped, and I heard a motor stuttering (the sound I would hear if the PWM went too low for the channel). Fortunately just prop damage because of low altitude.   I'm trying to figure out if this was an ESC/motor sync failure, or the PWM actually went too…See More

"Yeah, it's big.. The props on it now are RCT foldable, which got lots of attention in the balancing and polishing department.  One of the reasons I chose this frame was because of how the front arms folded back, I'm hoping to make the…"
