Thread: 4500EE + autopilot

    4500EE + autopilot

    My RV-7 has a 4500EE, AFS Arinc, AFS 73101 gps, and Digiflight II VSGV autopilot. The autopilot will fly the plane very well in altitude hold and heading hold mode. It will climb and descend, and turn left or right just fine. BUT, when I try to get the EFIS bugs to control the autopilot, I get a climbing right turn, followed by a descending left turn. It will keep going right and left, up and down if I let it.
    I have been thru the EFIS setting and the autopilot settings several times, still does it.
    The Arinc power LED is on.
    I am running out of things to check. ANY IDEAS ??????

    Thank you,

    Gary

    1. Email a picture of your EFIS autopilot gain settings
    2. Are you sure the autopilot arinc lines are connected to the AF-ARINC and not wired to a navigator?
    3. Are you in GPSS or EXT LS mode on the Trutrak?
    4. Does the stick follow the heading bug on the ground with the autopilot engaged?

    Email me the settings and we can arrange for you to call while you are at the plane, Rob@Advanced-Flight-Systems.com
