Hello guys, I'm very familiar with the NAZA M IOC system and used it plenty times to my advantage as its a great feature to have esp home lock in case the phantom gets too far and lose orientation. I've heard before on the forum that if you get too far, home lock no longer works and I've heard otherwise Yesterday was a scary day. I flew my bird out to avoid 1200ft from my house, still had video feed but I wanted to bring her back but didn't know the nose orientation. As you can see on my video I have full control up until to 0:07 mark and That is when I engage home lock. For a split second it begins to go towards my house which is visible on the upper left side of the video but it changes couse and goes farther and farther away from my house over the freeway which I did not intend to happen. By the 0:21 mark I realized it has flow farther and that is when I let go of the sticks and now video feed is cut, phantom is out of sight. No control at all. You can see my phantom hover and I immediately switch to fail safe mode. At 0:29 seconds the turns and cripples towards home. The rest of the video shows exactly that. I'm really starting to believe home lock isn't very reliable. I compass calibrated as I do every flight. I had NAZA M mode on. Ive done home lock before. It was scary not knowing what happened to my bird I was already thinking about how much the new vision plus is going to cost me as a waited there about to cry lol Can someone give me any insight on what happened? I'm not ruling out pilot error either so feel free to chip in thanks !!
