Recently purchased a new APM 2.6 along with the Ublox-6M GPS/Compass combo.
Stabilize and ALT hold mode are perfect, however when I switch to LOITER It immediately flies off in a random direction.
When in MP it shows an excellent GPS lock and the position is correct.
I have verified compass calibration is correct via an external compass, everything is dead nutts.

Like I said, GPS is excellent in MP, even indoors.
