[QUOTE="mcven32, post: 56128, member: 11599"] This started with a crash where I broke the gimbal. I replaced, but broke the IMU ribbon in the process. I then replaced the IMU ribbon, but then broke the front sensor ribbon in the process. The gimbal, IMU module, and sensor ribbon have all been replaced using used eBay parts. The gimbal, front sensor, and downward sensors are not connected in the picture below, but i have connected and disconnected everything 5+ times to ensure nothing is loose. [ATTACH=full]5799[/ATTACH] I receive all of the following when turning on the device. [ATTACH=full]5801[/ATTACH] I receive the following when I try to make the aircraft takeoff, but the GPS is completely connected. [ATTACH=full]5802[/ATTACH] I did a factory reset and downgraded the irmware to see if that would help--No luck. I have a feeling the the downward vision sensors are causing a gimbal motor overload error that comes and goes and causes the gimbal to move erratically and position itself looking unnaturally upwards at roughly -10 degrees. All ribbons appear to be fully connected and compass/IMU successfully calibrated. [ATTACH=full]5804[/ATTACH] [ATTACH=full]5803[/ATTACH] The only issue I can see are a few broken pins on the motherboard that connect it to the IMU module, but again, the IMU is calibrated without issue. The downward sensor is clear and unobstructed. [ATTACH=full]5800[/ATTACH] [/QUOTE]
