Hello, during a test with Arducopter and latest firmware version the quad started to gain altitude in a uncontrolled way, so I noted that the GPS was not fixed during this starnge behavior, the I disegnaged ALT HOLD recovering the fligth capability
So I wait for the fix then I tried again , ALT HOLD worked very fine any type of problem.
Then next day I redo the same tests and I paid attention to verify that the GPS was not Fixed, the result was the same : unexpected and quick altitude gain.
Obviously the throttle stick was at the middle.
So, this issue is known ? I parametrized in a wrong way the quad ?
Suggestion ? Asks ?
Regards
Paolo

I'm not an expert, but I don't thing GPS is used whatsoever in ALT_HOLD mode. Do you have sonar? If so, try without sonar.
