Hey guys, so my gimbal used to be able to look up and down by using the knob control on the left corner of the Phantom 2 controller. Somehow, it stopped working though, and only stays at a 45 degree angle. Besides that, the gimbal works fine, it just doesn't respond to when I try to angle up/down. I am in NYC area. Any idea on if I can fix myself/someone who can? I bought off amazon and dont really have receipt or anything but could probably track the order down. Thanks!
