I am facing some issues listed below

1.If i hover the drone it is oscillating Z axis up and down within the limit of 0.8m to 1 m.

Did you tuned the altitude controller?

What Flight Controller is this?
Does the Manufacturer of the craft offer support for the mystery firmware?

Ad says it’s plug and play, no support needed

Well there you have it! Problem solved :slight_smile:

I see their GCS has an advanced tuning section including configuring Auto Tune.

Put it to work.
And, is this firmware based on old V4.4 like that other craft you have?
