Ok I updated and range checked the new Optima 7 out side the plane. Still had link at over 150 feet so I am assuming my first Optima 7 is bad, but I still need to range check in the plane and while running. Is it worth it to send in the bad receiver for repair ? Its never in the air but I have had it for over a year so there is no warranty . I also have no idea where to send it .
