I just got a P330D, used on "that auction place" (yes...I know). On first power on, the attached gimbals didn't go to "home" position, they just continuously flopped around, and the rotor motors would not power on. I did seem to get the correct start up self test sequence, and a flashing yellow light until I powered on the controller and then it went flashing green. I downloaded the NAVA software, and was able to connect to the unit just fine. I am able to see all control movements, and they appear to be calibrated correctly (both joysticks start at center). I did change the gimbal limits to 500 from 1000 (max). I am also able to successfully do a motor test, the correct motors responded in sequence, and I successfully did a calibration. Now, even though power up still appears correct and the gimbals have power (on-board LED's are lit) it does nothing on power up (hangs limply) and I still can not fly. This unit was supposed to be working, and from all I have read, should be. The LiPo battery was just fully charged, batteries in the controller are new. The gimbal is for a GoPro, but there is no camera attached. Any suggestions would be appreciated. P.S. - it was shipped from CA to IN inside it's foam lined hard shell carrying case designed for the Phantom.
