A few months ago, I made my first quadcopter with following specs:
cheap f450 frame
1000kv aliexpress motors with 30A esc’s
4s 5500mah lipo
battery monitoring module
After a few turbulent tests I fixed most of the major issues. But the next test started in stabilize and after switching in loiter the quad was stable for about 5 s (like it schould, constantly correcting) but then it abbruptley accended to 30m (from 2m) with the throttle in 50%. Something worth noting was a kind of delay I felt when handling the craft. Then I panicked and switched back to stabilize to land the craft safeley. Afther that I Reinstalled the firmware and did all the callibration again.
I don’t know what caused this. I checked the barometer and the measurments seem reasonable. I Attached the log below. Something worth watching is Alt, BarAlt, GPS; Alt. the x/y movement looked stable
Can anyone help?
