Hi, all.
Recently, I met a problem regarding altitude drop.
I had put a foam between DIMU and AQ6 to cover the barometer.
Yesterday, I spent 8 hours to do various tests.
However, I cannot overcome this problem.
Every test was 15 minutes.
In position mode, I let my AQ 6 flied forward again and again.
For the previous 3-4 minutes, the altitude was held well.
Then, the altitude was dropped.
The mag and acc were close to 2.1 and 9.8, respectively.
No visible vibration existed in the log files.
I also tried various foam materials.
The similar altitude drop occurred again and again.
Based on the tests, the accuracy of Baro became bad associated with time.
Does anyone have any solution?
Is the configuration of PID not well?
Thanks a lot.
