I have recently bought a Phantom 2 with a H3-3D gimbal. Using the Phantom software I have slowed the rotation of the gimbal to get a slow smooth pan, but while the lever on the back of the remote has a wide span of movement, the gimbal only moves when it's right at the edge of the possible movement area. This means that for the large part, moving the lever doesn't do anything, but then just at the very edge it makes the gimbal pan from fully forward to fully down without giving me the option of stopping anywhere in between. Is this just how the gimbal lever works or is there something I need to fix?
