Quad Copter, X configuration. Blades and airframe is balanced. Huge compass interference, could this be why I can’t get stable flight? This is also the first time I’ve used the PID starting values based on cell count and prop size so I’m not sure how accurate it is.

You didn’t set PSC_ACCZ_I and PSC_ACCZ_P to reflect MOT_THST_HOVER and ATC_THR_MIX_MAN is also still default. These should have been set after the first test flight and Mission Planner tells you that explicitly.

Your PIDs are completely untuned/default. ArduPilot is not plug and play!
Read and follow the How to methodically tune (almost) any multicopter using ArduCopter 4.4.x guide. Download the .zip folder with the param files from the guide, edit each file to suit your copter and upload them one by one as you read along. The guide tells you what to do and which file is needed at any given time. Do not skip any steps! Anything that might seem like a shortcut will result in a worse tuned drone in the end.
