I have a problem with one of my pixhawks…
I buit 2 drones, both with very similar hardware
Pixhawk (HK clone)
One is a quad, one a hex.
The Quad so far has worked just fine.
On the hex, it is another story.
The first battery works fine. It acquires GPS signal, I take off, flys good, GPS modes (drift, hold, RTL etc.) work fine.
I land, take off the battery, attach a new battery and take off again. It is without power anywhere between 20s or 5min, doesnt matter.
Now I take off in stabilize, everything works fine. As soon as I switch to a GPS mode (drift, hold RTL etc) it “leans” to the side and drifts off in a random direction. In RTL it fails and switches back to stabilize, in hold as well sometimes.
Anyone have an idea?
