Hello, My compass has been calibrated and no red lights, indicating full satilite link. However, when I wish to hover (with left stick at 50% and right stick untouched) my phantom drifts to the right at about 3-4 MPH. Other than this it works fine, and I can fly it normally so long as I counter the rightward motion by tilting the right stick slightly to the left. Any ideas about what causes this? My phantom is right out of the box (no software updates because I use a mac and the software is not available).
