Hi
I hava a quad with s500 frame
Simonk esc 30a
Emax mt 2213 935kv
Pixhawk 2.4.8
M8n gps
My quad take off in a nice way and hovers good in both alt hold and loiter mode but when i started descend it wobbles rapidly … and become unstable when i release the throttle it becomes stable again … but when i descent it happens. I also done esc callibaration and all callibaration correctly not done auto tune yet ? Should i do an autotune to this ? Please give me a ans .
Here is the log file
Probably instability because of incorrect MOT_TRST_EXPO parameter.
You need to tune a lot more and a lot better before you even think about autotune.
See the methodic tuning Blog post first.

You are flying on default parameters and have set none of the pre 1st flight parameters.
Also, this craft looks to be underpowered/overweight.
