So I am at the end of my rope. I cannot get my quad to be even the most basic stabilized. In no wind it drifts all over roll, pitch, yaw. I have calibrated the compass, accelerometer, radio…everything. Ran compass mot several times to make sure interference is less than 30%. I have run auto tune several times to tune the PIDs. The only thing that works ok is altitude hold, but stabilize and loiter are a disaster causing a couple of dozen crashes. I must have something in my configs that is way off but I can't find it. Any help would be appreciated.

So I replaced the GPS module in case I had some form of hardware issue but I still see the same issues. Yaw drift and crazy flyways when in loiter mode. The quad can't stay in loiter mode for more than a minute or so before starting to fly away fast. Looking at the logs, there is always 7+ satellites and an acceptable HDOP. There is nothing in the data that correlates with when the rig starts to fly away. The GPS module is on a 9cm mast.
