What happened

[Jim622]

I was out for a short picture-taking adventure this morning. The drone was working as expected. I was at 380 ft agl and about 4,000 ft away, and it was showing a full signal.
The controls suddenly wouldn't do anything. I tried to yaw left or right, and nothing happened. I tried to move forward very slowly, and it wouldn't move. It showed that it was moving 1 mph, but it didn't look like it was moving. I checked the signal strength again and confirmed that I had a full signal. I hit the RTH button, and it returned precisely as it should have. Do you have any ideas? Or am I just goofy?

Upload your TXT flight log here and post the link back here. Then, we can review and discuss.

What I see in the log is that the mode changed from P-GPS (bypass) to P-GPS. I don't know why or how that would affect it.

That change wouldn't have caused any of the issues you mentioned above.

 

[Jim622]

That change wouldn't have caused any of the issues you mentioned above.

So I am probably just goofy, then? LOL. What would cause the mode change? Topagraphy? Elevation?

I'm not sure. Can you share your flight log?

 

[Jim622]

I'm not sure. Can you share your flight log?

Just sent it to you. I am from PA too, by the way—Pittsburgh area.

You probably have max distance set to 4000ft
If you had rotated 180 degrees, the controls probably would have worked again.

Your flight log shows the max distance from the home point was 383 feet.

This Flight Reader chart shows the elevator (forward/backward) was responding as expected from the time the flight started up until you initiated RTH on the remote controller:



This chart shows the aircraft yawing each time you commanded it to do so:




What was the exact time in the flight log when you were attempting to move the sticks and nothing seemed to be happening?

What was the exact time in the flight log when you were attempting to move the sticks and nothing seemed to be happening?

It was shortly before I initialized the RTH. 5.55 until 6 00. It showed a command to go up, but I don't recall doing that. I was already at the max altitude for this flight.

Can you post the flight data?

Can you post the url of the Phantomhelp report?

At the beginning of this chart, it shows you moved the throttle stick up and the aircraft responded by increasing its altitude. And then shortly after, you initiated RTH. For reference, 360 below is the 6m 0.0s mark in your flight log.

I don't recall moving the stick up, but it is in the log. I do recall moving left then right for yaw, that is not in the log. is that possible or am I mistaken.?

I've never seen a flight log with incorrect stick movements documented.

While I suppose nothing is impossible, data in DJI flight logs has historically proven to be highly reliable.

If so, I must be mistaken. I will monitor it closely for a while to confirm that there are no issues.
Thank you for the help. I appreciate learning about the logs and how to access them.

Are you going to past the URL of the phantom help page ?
