I bought a phantom fc40 last month. Everything was working perfectly fine, until I decided install a Gimbal. The process of installation worked just fine, but after i finished my work, I noticed that one motor didn't work. The indicator LED of that motor was always turned on. What's wrong? How can I fixed this problem? I've already tried everything and nothing seems to work. Here is a link of a video I made to show you the problem. https://www.youtube.com/watch?v=tcnaMx_ ... e=youtu.be Please help me, because I really love my phantom.
