My Phantom Vision 2 had three modes in IOC (intelligent orientation control) or NAZA mode. These were…home lock, course lock and regular flight or GPS mode. I love these, especially home lock! I used it when I could not determine what direction I was pointed. I could simy pull back on the left stick and it would return to me no matter what direction it was facing. In looking at the pilot app, I only see an option for course lock. Is there a way I can establish home lock? Thanks in advance for everyone's assistance.
