As a noobie I am asking for someone to review my data log.
I have a 500 series quad that I purchased pre-built. So far I am very happy with it but have had a couple of occsions where it would not disarm and I had to unplug the battery.
When this happened the first few times I thought it was my error. But recently I am more confident my actions should have disarmed the quad. Also this seems to happen when landing in RTL or Loiter.
Saturday it was windy and area of launch a bit restricted, so I chose to use RTL as the GPS modes (loiter, RTL, and auto missions) have been spot on. Upon touch down I placed left stick full down and full left. The props almost came to a stop then suddenly sped up just enough for a hover less than a foot of the ground while at full left yaw. Needless to say it touched back down and flipped over. I have attached the data log from this event.
On my next battery I landed in stability mode and was able to dis arm with no problem.
On my third battery I got into some brush causing a crash and again I could not disarm with left stick down and left (loiter mode). Log for this event not attached.
I don't fully understand how to graph all the info but was able to show altitude, throttle in, and throttle out in screenshot also attached. I think this shows throttle input was correct but APM over-rode and raised throttle for some reason.
