Hi, I use the movi M5 mostly on a cinestar HL. In almost every flight I experience some weird roll issue. The horizon is straight during takeoff and turns lean during flight. Even when my cameraoperator trims it back to "neutral" via the Spektrum DX7 it will not stay there. It really messes up the whole picture and we don't know what to do about it. Tried rebinding the controller already. Roll stiffness is at 87. Has anyone gone through the same trouble yet? Can you guys help us? Looking forward to your replies, cheers manuel
