I installed the 777 in quite a while back and it has seemed to work flawlessly but just today when everything was setup in the fmc and the flightplan setup, the pane took off but had this 2 to one second hiccup before i lose all control of it and its stuck in the position i left off. the control surfaces move but the plane doesnt seem to budge. after that i tried using it without a flightplan and it seems to work just fine so its definetly something wrong in the configuration of the aircraft modified by something like fsuipc. but even after delete of fsuipc and other 777 effects it still doesnt work even after a reinstall. someone help pinpoint where this issue is coming from
