Alt Hold/Pos Hold jerk

Hey guys,

HERE THE LOG

Unfortunately i was not able to tune a copter as it has some jerking when switching from stab to alt hold/pos hold. Slight pulsing 10cm jumps and jerk while holding alt. i have never experienced this before. Thr_mid is set correctly at 25%, did an autotune reset parameters etc. it is not locked in as with my other copters. FCU is damped, props are balanced. Did play arround with the ins_ filter (15-20 hz) settings but did not help except in the logs. Any idea what else could be the reason?

Thanks,
Tom
