It’s been 4 days of PID tuning and I can’t seem to find the right PID values for a stable flight. I keep seeing ghost (or unwanted) movements besides the drone being sluggish even when flying in stabilize mode and it is quite scary!
At first, I was able to manually tune the PID and achieved a relatively stable flight for AutoTune. However, after letting ArduPilot do the autotune, the result was still not so good. As I said, I can still see ghost movements which I think it can get worse on windy days.
I’ll appreciate it if anyone can help me tuning the PID. The few blogs I found about tuning PID on big drones were not really helpful. Maybe sharing your PID values could be a good start. Thanks!
Here are the specs of my drone:
- DJI M600 Pro frame and original motors with 21in props (foldable)
- Flycolor X-Cross HV 80A Blheli_32 ESC using Dshot150
- Pixhawk CubeBlue with ArduCopter 4.1-rc1
- Dummy payload of 2.4kg so that the motors don’t run at too low rpms
Here is the autotune flight log (only roll):
