Can be in perfect trim and stable. Then engage hold mode and still get oscillations. When trimmed at a hover, engage hold mode, and aircrafts rocks all over the place before stabilizing. When cruising and in trim, engage hold mode, and aircraft rolls to the right, yaws back and forth, or pitches down/up- this one happens half the time. Other times it stays in place as it should. When disengaging hold modes, the aircraft is goes way out of trim and must be corrected immediately. Please hot fix and don't make us wait another 2 months.
