So, finally got my FY-G3 installed on my Phantom. Not a whole lot of info out there on how to do this. Thankfully, I found another pilot here in Jacksonville and he walked me through a few things on the phone (he's got the same setup). Problem is, we're both experiencing a similar problem--the Phantom won't reliably hold position now that the gimbal is installed. Mine isn't holding altitude nor side to side position. The altitude may have been partially my fault as I just added all of that weight but I got it up then it started coming down slowly and was drifting. Before, it was solid as a rock on positioning. I even recealibrated the compass before I flew after I installed the gimbal. Since there is no information I can find anywhere on how to power the gimbal, I just connected the power right off the cable for the battery. Not sure if this might be a problem? Other than that, I really have no other ideas as to what the problem might be. Hoping someone else might have some ideas. Anyone else experience this?
