I'm still building my confidence while learning to fly so don't really do anything too risky ! One manoeuvre I practice regularly is to simply rotate on the same spot in order to film a 360° panorama. It seems that when videoing the quad very often drifts considerably from it's start point (20 to 30 feet before I panic) and the 'GPS signal lost' warning appears, yet I can carry out the manoeuvre and not video and it remains absolutely in the same position. Any thoughts please ?
