Phantom 2 V2 Non Vision 3.08 Firmware Installing a gimbal and FPV setup - Immersion 600, Mini IOSD, Black Pearl Monitor. Installed everything and the first power up the gimbal twitched around. When I moved the wheel the movements on the gimbal were exaggerated. It didn't seem right. Updated the firmware. It said to power cycle and now the gimbal does nothing when I power it on. It came with an anti interference board and I believe I have it connected properly. I removed it (and the Immersion) from the equation but it made no difference. No clue where to go from here. Edit - I have calibrated the RC and Phantom and done an advanced IMU.
