Today me and a couple of guys at the field determined it was the radio. We put the 7610 into an old trainer and sent it up with a data logger. We lost control of the plane in the same spot again but we didnt crash it. When we looked at the results, the battery voltage was normal the whole time BUT we had obvoiusly lost the signal once because all of the servos went to their failsafe positions at the same time for about 4 seconds. Next we tried an orange reciever and the same thing. Lost signal farther out (200 yards). I have also had this same issue in my yak BNF and my cub. Not sure what to blame now other than the radio unless i am doing something wrong. Now I am scared to use my spektrum!! Maybe i got a lemon?
Thanks for all of your help guys
