In the P2V+ with NAZA-M enabled there was a lock to home option - useful if the orientation of the plane was unknown. Using Back always brought the plane back to you. Seems to be something similar with the P3. I've enabled IOC and set it to F-Mode. But pulling back doesn't seem to pull it back to me but some random direction. I tried the reset option but that didn't help! I had a look in the manual and it says "Home lock coming soon!". It appears its locked to course lock. But as far as I can see you can't actually set a course! I tried creating a guide line - which worked - but couldn't then see a "GO" button to make the plane follow it. None of this stuff is in the manual and obviously limited help online due to its newness. Anyway help or point me in the direction of a tutorial for these features?
