Hi Folks, I'm really struggling with an altitude problem on my quad. I've tried every tweak Google and other postings could bring up. The problems is this:
1) In Alt_Hold or Loiter mode the quad will gradually rise, or more often than not it will sink slowly towards the ground.
2) All the Altitude readings look good, in fact the DAlt readings make it look to me like the quad is simply doing that it thinks it's being asked to do. But I'm not the one asking. My throttle is mid! Input levels are the same, but DAlt is graduallys saying "descend".
Nothing I do changes this behavior. I sometimes randomly get good performance for up to 2-3 minutes, but then it manifests. Here's a quick log snippet illustrating the issue. I've also attached a full log for review. Any help would be tremendously appreciated. I'm 100% at the end of my rope on this.
Note the DAlt behavior. Why...in....the....heck....is that changing? It pulls my quad up, and then takes it down. My quad is doing what it's told - but told by who???
