What happened here?

Post by Leo »

Everyone,

I need some guidance on what could be the cause as seen in the video.

I had flown one mission just before this flight on the same battery.

The quadcopter had an OSD-Navlink + camera + 5.8GHz transmitter and 3DR transmitter for telemetry on-board. I've flown the QC many times. The OSD was only recently mounted and the camera was new which was running on it's maiden flight before this one.

Battery still had 3.85 V after I checked the QC. Also there were no loose screws or loose props of any kind after inspection.

Any ideas what the cause could have been?

It looks like unwanted software interrupt...... Floating input somewhere?

Best regards,


Rob

I flew 2 battery packs yesterday and I couldn't repeat the behavior. I am quiet certain it's not hardware related. I've double checked the QC and couldn't find anything out of the ordinary.

I wonder if the PID's changed in-flight causing the oscillations? Maybe the MinumOSD interfered? I haven't a clue.
