Don't know if this contributes.... Firstly, I am a new flyer. I've NEVER flown a drone in my life,... until now. Purchased a
Mavic 2 Zoom, with accessory package. Flown it at home. (Went thru 3 batteries and took some beach pictures that were kind of far away.)
Brought it to work the next day, which is approx. 25 miles away, and tried to fly it there. Received an error - something about magnetic error?.. 'I think?' Went thru re-calibrating the compass without any problems. Then, had to do the same with the IMU. Attempted 3 times, in 3 different locations, that were approx. 100 feet apart. It failed on all 3 attempts. On the 4th try, it succeeded. (Remote showed 11 GPS Satellites acquired.)
Next, I got a prompt that an RTH was acquired when I utilized the '
Smart Controller' to auto take off.
M2Z hovered about 4 feet. Then, it started to 'slightly' move left and right. I took it to a higher altitude because surrounding obstacles were at a 10 foot radius of it flying left and right. Flew the drone away from me at about 50 feet, and released all controls. Unit hovered, but still continued to move laterally sideways. Then, I utilized the 'RTH' function. Drone flew back to me, but was going to collide with the building that was about 15 feet away from take-off. I think that the controller starting beeping?, so I panicked and hit the 'RTH' button, 'up-down, cancel' button, and moved the left stick backwards. Unit hovered with controller constantly beeping about the building in front. I turned the drone away from the building, moved forward, and manually landed. Just out of curiosity, I did another auto take-off. My controller notified my about a new 'RTH' location and to check my map?
I landed and quit for the day. Today, (the next day,) I re-calibrated the IMU and Compass at home. Successfully completed on first attempt. Will try to fly it, but am quite nervous since yesterday.
Sorry for all of the details. Just thought that it may help if anyone finds a similar situation after travelling 25 miles, re-calibrating the IMU (with failure attempts), and finding their unit acting abnormally.
