Hello again guys,
yesterday i asked i question about my a high autotune value here:
Mr. andyp1per, told me that everything was ok so today it was the day for checking my new tune.
Stabilize, Althold are pefrect, the copter seems tuned quite well, a day and night difference before autotune.
BUT Loiter is not good, copter oscillates quite a bit, on roll axis mainly (as i can see). You can also hear the motors make that vib sound… I’m afraid to try other gps enabled modes with that behavior… Something is wrong…
I searched about this issue but i’m not sure what to do. Could someone please have a look at my dataflash log and give some guidance please?
I uploaded the file here:
Thanks in advance

i don’t understand your comment.
All necessary steps to manual tune and autotune the drone were followed. It flies perfect except in loiter. Did you ever had a look at the log? I don’t think so.

This craft is underpowered/overweight.
This could be trouble when a higher thrust demand is required. You will know when you receive Thrust Loss errors when the outputs max out.

maybe, but i dont think that this is related to the loiter oscillations.
moreover the problem exists with or without the camera payload.

Maybe true but you should have addressed this thrust/weight issue before getting very far.You will have to re-tune it anyway after it’s corrected.

i found this:
I know it’s been a while since you first posted, but try these and see what happens, post another .bin log if you like Update the CAN GPS firmware Update the Arducopter version to latest stable Connect to MissionPlanner, Initial Parameters, put...
tomorrow i will try halving PSC_POSXY_P and PSC_VELXY pids and see. I will report back the results.

Solved. Lowering PSC_POSXY_P and PSC_VELXY pids by 60% solved my issue.
