Hi everyone, First post here - been reading most of the posts. Great to see such an active, friendly community focused on the Phantom. First some backstory -- A few weeks ago my phantom took a pretty nasty fall. One of the propellers separated from its motor mid-flight about 50 feet up in the air. The resulting crash damaged one of the motors. I replaced the motor, calibrated the IMU, and took her out for a test. The phantom is flying well in ATTI mode, but in GPS mode it now tends to make 5-10 foot circles instead of hovering in one place. It doesn't matter what direction the drone is facing; it consistently makes clockwise circles with a radius of 5 to 10 feet. In attitude mode, if there is no wind, the phantom hovers in place. Any thoughts on what could be causing the circular flying pattern in GPS mode? Thanks in advance for all insight!
