My Holybro Pixhawk 1 quadcopter takes off ok in stabilize mode, but once off the ground and in loiter mode, its behavior becomes unstable. It does not like stabilize mode, and I am forced to put it in land mode and bring it down. Everything seems fine on the ground. Here is the flight log:
That’s not a flight log it’s Auto Analysis of one which has very little value. Post a link to the actual .bin log file.
I’m not sure how this works. Post a link to it? Can I copy and paste the file somewhere?
Not here, no. Use a cloud service of choice(Dropbox, etc) and post a link to it here.
It doesn’t look like it’s flying in this log. Can’t do much with that.
That file has an access requirement. Why don’t you open it in Mission Planner, graph the Baro>Alt and confirm it’s a flight log useable for troubleshooting your problem. And then remove the access requirement.
How would I do that?
And do not forget to update to ArduCopter 4.2.1
I went to the logs page. How do I open a .bin file to do something useful with it? How do I open it in Mission Planner? Thanks.
Go here and select the Review a Log button. Presumably you downloaded and saved the log from the Flight Controller 1st.
Ok. Did that. I have a log browser window open.
There is a red and blue line diagram of the flight path. What I would like to know is why the aircraft stumbled in mid-air when I changed flight modes from stabilize to loiter and then shot up in the air when I switched back to stabilize. It would not hold loiter. I had to bring it down under land mode. Thankfully it came down slowly.
Post a link to the log where it’s flying.
There was a line in the text version of the log that stated a large magnetic variation occurred, but I can’t imagine why that would be. I have seen the same effect occur on previous occasions.
As I said that message has little value.
See if this works: https://drive.google.com/file/d/1S3KC5zgqjd-rsfuaRdhWy1QmJn1uRNCE/view?usp=sharing
There is nothing top see in this log and it’s in Stabilize there is no Loiter. Make another flight, fly it around and post that log.
