After installing a GFC500, dual G5’s I did a test flight. After reaching about 5K agl I engaged AP To NAV/GPS.
210 was stable and engaged Alt hold. It began small alt changes which increased to a point from 50’ to 500’.
after disengaging AP I reestablished stable flight and tried it again, and again. Same result with wild increasing oscillations. Back to the shop and explained what was going on we determined it was significant slack in the bridle cable that was causing a serious problem. After the fix of adjusting CORRECT cable tension the GFC 500 is solid, even in continuous mod turb. Hope this info may be of some help to someone, even if it’s is not related particularly to this thread.
