I downloaded the latest firmware edition and the Phantom Default configuration parameters which is a zip file on their website. No matter what I seem to do, I cannot open the zip file after downloading. Now, my new Zenmuse gimbal keeps panning up and down... The Zenmuse behaves perfectly when powered up as long as the RC is not powered up too, so I am sure something is wrong with the RC calibration and I just cant seem to get it right. Does any one know what I should do? Please Help!
