Today (March 3) the latest main controller firmware 3.12 has been released. The bad and revoked 3.10 seems to be "repaired" and now reborn into 3.12. Release Notes: Major New Features 1. No-Fly Zones have been updated to include a 25km radius centered in Washington, DC. 2. The compass calibration program has been optimized to improve reliability. 3. When automatic landing is initiated, users can now continue to control the aircraft’s position and altitude. During this process, the maximum speed of ascent is 1 m/s. 4. After an automatic landing has been completed and the motors have stopped spinning, users can immediately restart the motors and begin a new flight. Special Note 1. It is recommended that the compass be calibrated in an environment that is free from sources of potential interference. If you become aware of any source of potential interference, move to a different location and calibrate the compass again. Be aware that underground metal pipes may cause interference when the aircraft is close to the ground during compass calibration. So... do horror stories continue, or has anyone loaded and flown 3.12 already - without problems? The changed/improved compass calibration might be something to be careful with, as a while ago I had a sideways crash (turned out to be a compass calibration problem) after DJI had changed something with this in an earlier firmware also. Looking forward to hear/read about some reports.
