I have flown my phantom for about 200 flights. I would say about 5 times I would be flying around and then see the phantom tilt about 45 degrees for an instant then level out. Almost like someone just hit it, then it stabilizes This is random and I can't seem to pinpoint it. A couple of times I would be trying to move it sideways or forward and nothing would happen, then it would tilt violently to make up for the delay in signal, then everything would be OK. Note: I fly in out of the way places, so there are no cell towers or power lines. I can only think of the following that could be the problem; 1) bad battery, or bad contact 2) bad motor or bad ECU board 3) I doubt it is the remote, since all green lights are on. 4) possible bad solder and need to check connections? Any other ideas? While I am here, I also had 1 flyaway, but was able to get it back using Homelock and RTH. No idea what happened here too. I was flying for about 10 minutes, then it just started going away (not fast). I let go of the controls and checked that both switches were up and they were. Phantom was still flying away, so I quickly put both switches down and pulled back on the right knob. I checked it out and didn't see anything obvious and flew it about 25 times since. Any ideas here?
