"It does sound like, it could be a hardware fault. Did you check the battery itself for any lose wire? Also did you do a voltage reading of the battery after the crash? Furthermore, what ESCs are you using?"

"Thank you so much Stephen Zidek for your clarification. As you said, the region with zero current at the first minute is due to the landing of the quad, I did a first flight in order to be sure everything was OK ( with no luck). I agree with you…"

"Darius, you still have a lot to learn about logs before you hand out advice.  According to the log, Carlos took the copter up, then landed it.  The region you see with zero current draw, and with the bump in accZ, is due to Carlos landing…"

"Carlos, adding to what cala and Michael are finding I see that current goes down to 0 quickly at the same time. that may be because AP is cutting some motors to stabilize, but also it can be some issue with power…"
