I have owned the Phantom Vision 2+ for about one month, and successfully flown about 10 times. When I took it out to fly last time, the throttle simply would not respond. After reading all over the place, tried the calibration which finally worked. Now, when i calibrate on the RC assistant, all appears well, however, on the phantom, there appears to be no link. I tried the "relink" process according to the manual, where the light underneath the phantom starts read, then you reset it, it turns yellow and it is supposed to turn off once you turn on the controller. It stays yellow.....any thoughts?
