Again a hard morning...
After a prop failure 5 days ago I have now really trouble getting the copter with v3.0.1 into air. Before the crash I flew the RC1 version of the 3.0.1 Firmware without any problems. Now I switched to 3.0.1 and didn't change any parameters (PIDs).
What I discovered so far:
- The Motors start spinning harder at low throttle than in the older firmware.
- If I give a little more power and then it immediately flips to the right. I tried that now 3 times and every time it did flip. I checked the motors, exchanged the ESCs, recalibrate them, checked the Props but nothing I can't figure out why it does happen...
here is a small log from today’s flip and the config file from my QAV400...
It is good that you have made progress, well done!
Yes, it is essential that the APM be included in the ESC calibration. When you perform the all-in-one method, you allow the APM to set baselines for each ESC. The APM will be driving each ESC as it needs to make your quad fly.
On my most recent scratch build, posted on Instructables HERE, I used a servo tester to check ESC/motor directions before getting the APM involved. I observed the same calibration behavior from the ESC while using the servo tester; same series of beeps and responses at the signal inputs.
I suggest you read the instructions in the release thread over here.
Watch the videos on how to set up your quad correctly for 3.0.1.
There are PID changes you may need to make. If you reload your 2.9.1 parameters you will probably have problems.
Could you post the *tlog? That is if you haven't cleared everything out yet.
HERE is the method.
You can confirm motor direction by using the CLI command HERE.
I have compiled the most common results of 'flipping':

...or combinations of any and all of the above.
Did you mean to set RATE_RLL_I and RATE_PIT_I so low? You have them at 0.005. I'm at 0.1 which is quite some difference.
