I just bought a Vision + and the first night I unboxed it and turned it on with no props, all seemed well with gimbal, wi-fi connection, motors spinning etc. I went out to the shop last night to plug in the Assistant software to program Naza settings, etc. and the gimbal went bezerk as soon as I turned it on. It flips and flops violently over and over. I have tried it many times and it stills goes bezerk. As anyone had this problem? Any thoughts? Thanks for the help!
