After completing a few flights with my drone which went buttery smooth, I went for another flight yesterday where I’ve experienced some unexpected behavior in Alt.Hold which ultimately led to a severe crash and loss of controls. I’m fairly new to Ardupilot and aside from completing the Initial Setup I wouldn’t have any experience in analyzing the logs. I hope that someone could point me towards the errors in my setup, so that I’m able to fix them before repairing the damaged drone. Vibration levels appear to be okay-ish in normal flight with room for improvements.
A video of the crash and the log.bin are attached. Before impact the drone appears to go into a very steep pitch, exceeding the set limits for its attitude. Not sure how time zones are translated in the log analyzer, but the scene in the video happens at 13:12 local time.
It’s seems like it’s a hardware problem. Check your all connections, especially power connections that comes from battery to esc and BLDC motors. There should be some electrical sparks causes short circuit or sudden disconnections, maybe a loose plugs or wires.
Nice you almost got all “component editor” window parameters correctly. I corrected some.
A vehicle.jpg file is missing.
I also corrected some parameters in multiple files: GEPRC_carbon.zip (49.5 KB)
You left all other parameters at their default value. And that only gets you an un-configured vehicle, NOT a configured one.
