I've flown about 5 times now with my PS3. I've calibrated the compass a few times, but since I'm flying in areas that are very close to each other I haven't done it each and every flight. Last night I took the PS3 up to 200 feet, went about 500 feet, and then did an RTH. Everything worked as it should and I hand caught it. Since I still had plenty of battery left I thought I would do another flight. I put it on the ground and did an automatic takeoff. I typically let it hover for about 20 - 30 seconds to ensure everything looks good and I have enough sats locked in. When I was just about to ascend my display reflected a compass error. The bird started to fade right, up, and down and go toward a nearby pond. My thought was to not panic and see if I could bring it safely back. I basically had to fight against the compass error some, but was able to safely move it left and since it was already at an acceptable height I simply had caught it and killed the motors. It wasn't until I had it that I realized the display was saying something about switching to ATT Mode. I haven't tried that mode yet, but I guess it might have given me better manual control without the compass to bring it in? Regardless, have others seen this kind of behavior before? I can't even imagine what I would have done had the drone been at 200 feet and this happened. I'll obviously recalibrate the compass before I fly again, but I'm also wondering whether others have seen something similar or could this possibly be an indication that something is wrong with my drone? Again, I just did a compass calibration a day ago at a location that was maybe only a 1/3 mile from what I flew last night.
