Does anyone know how to setup the fail safe on a Radiolink transmitter? Any instructions online are useless and well as the manual. When I go into F/S from the main menu, all of the channels are listed. When I push the button on a channel I use the wheel to toggle from NOR to F/S, then it seems a random percentage appears. F/S is either highlighted with a box or solid like in the first pic. My problem is how to change the percentage. Any of the dials, toggles, sticks I push, I cannot get the percentage to change. If I exit out then go back in some other number appears. Either you are not allowed to change the percentage or I canot figure out how to. Any ideas on this?
