So what occurred wasn't a full-on crash, but I'd classify it more as a hard landing after brushing against a low-hanging tree branch. When a compass error occurred, it drifted on decent. One prop needed to be replaced after the last 1" or so of one end cracked off. Everything else checks out fine - no hairline cracks, no other damage. I replaced the prop, recalibrated the IMU and compass, and it flies like the first day I bought it. HOWEVER - one slight problem. The camera is no longer aimed directly forward. It isn't tilted at an angle -- the horizon is perfectly straight -- however, it doesn't aim directly straight forward; but rather it is off from dead-center by a few degrees. I've calibrated the gimbal a few times, but it seems to come back to this same center-point that is off-center. Any ideas on how to get this back to center?
