Adjusting servo gains. Roll is ok but cannot seem to get the aircraft to stop oscillating in pitc h without reducing the servo gain to a very low value. Can anyone with a GR T system let me know the gain and damping settings they are using to get me started.ThanksSteve ________________________________ Message 10 ____________________________________ Time: 06:55:45 PM PST US From: Rick Subject: Re: Lightning-List: GRT Autopilot What aircraft is the GRT in? When setting up the pitch you really need another set of hands to remove the effect of gravity on the elevators. Read the test manual carefully.
