The Ifly 740 works fine separtely but when I connect to the auto pilot, it works intermittently. I had this problem last year, replaced the cable and it worked fine till now. I giggled the cable going intom the Ifly and the connection was back on. Then I giggled the cable again and it lost contact. I don't believe this cable is also bad like the first one. Have you had problems in the past with this connectoin?
