I just purchased a DJI Phantom 3 Advanced and an extra battery. It has been shipped and should arrive this week. I am very excited about this. It is my first Quadcopter. I am a very cautious person and will exercise all cautions and start slowly getting familiar with this aircraft. I have been reading various threads here and just read about 11 pages about a Phantom that "flew away" and the pilot's stating he also was very cautious. So my question is: How frequently does a Phantom just fly away even after all due cautions have been exercised. Batteries charged, Compass calibrated, Go To Home point set, etc. I just do not want to see my $1148 fly away and have my significant other nagging me, she already is questioning why I would spend money ON THAT THING!
