Good morning all. I made a little helipad out of a card table to setup the Phantom 4 and lay out my equipment. Question is that the card table has metal legs and I was concerned that initializing the aircraft on the table could introduce some compass errors. I’m not sure. If I initialize away from the table can I then pick up the aircraft and place it back on the table? I’ve taken off and landed from it for practice and seems okay but I just want to be as sure as possible in this endeavor. As always appreciate your time and responses. Thanks !
