Hey Guys, I have tried everything and just cant seem to get this to work. Im trying to achieve a very clean and balanced take off, up and down, but even after several nazam advanced calibrations and manual compass calibrations, my Phantom seems to always (slightly) favor one side after take off causing it to slide in one direction. I have watched all the tutorial videos and done exactly what the manual suggests. Is there a step im missing? FYI: I'm currently doing these tests and calibrations in a warehouse store room where im sure I am getting next to no GPS reception. Thanks!
