Subject: [LML] LNC4 S-tec 55X altitude hold


During today's phase 1 flight I started checking the autopilot, an S-Tec
55x. When altitude hold is engaged the aircraft starts to porpoise. Acts
like the pitch servo is making a larger correction then is necessary for
the sensitive pitch of a IV. Has anyone had this problem?
