I just installed the new 3.0 Firmware on my Phantom 2. I also re-calibrated the transmitter. I have the Zenmuse H3-3D gimbal with a GoPro 3+ black. I took it out for a test flight and the gimbal does not work. It just sits level. It will not tilt in response to the tilt control on the bottom of the transmitter. If I turn on the transmitter and then the Phantom the gimbal "comes to attention" for a couple of seconds, tilts to about 45 degrees for a second and then goes back to level. However it will not respond to the tilt control. If I turn on the Phantom first the gimbal will wake up, sit at level for a few seconds and then tilt to 45 degrees and stays there. Then when I turn on the transmitter the gimbal will tilt back up to level and stay there but it will not respond to the tilt control Does anyone have any ideas on what might be wrong?
