Since I was anticipating using IOC since I forever lose the orientation of my Phantom 2, I switched from Phantom to NAZA mode. I have had several successful flights, but am no "expert", and only one bad crash. I calibrated the compass first, and set it to GPS mode. My first (and only) NAMA flight, I took off, went to about 20 meters high, and 30 meters in front of me. Then I turned the Phantom "around" so it was facing me. I switched to LH and then LC. I pulled the stick BACK, expecting the drone to come towards me, but it went left AND LOST ALTITUDE and nearly crashed before I gave it full throttle and barely kept it off the ground. At this point, and full throttle, it barely hovered, and I finally got it to limp back closer to me, where I landed. I thought NAZA was going to be great, but this has shaken me. I have switched back to Phamtom mode, but have not yet gone out again. Can anyone tell me where I screwed up? Why is there no "power" to go up? What have I done wrong? Help!!
