I was trying to film a sunset tonight and had turned on the Realsense module. I didn't particularly need it, but thought it wouldn't hurt. After about 10 minutes, I got the calibrate compass warning and the copter started toilet bowling. I started bringing it down and stopped at about 30 feet to figure out how I was going to set it down. Since I didn't want it to sense anything, I turned off obstacle avoidance. The craft immediately settled out and stopped toilet bowling...steady as a rock. Anyone had any similar instances?
