I just had to get a new P3 - I had some problems with the first that I received and the company sent me a replacement with a return label to send the other back. I'm currently sitting here with both. I tried updating the controller (would it have shipped with the most recent?) - no matter what I do - I tried a flash drive, an sd creader as well as hooking it to the gimbal. Flash drive and SD reader just show a red light instantly. Connecting to gimbal - camera points down and beeps every few seconds and there is a green light on controller. No log file gets created (if I do it on my other controller it will at least say same firmware etc). Anyone have any ideas or suggestions?
