The addition of a "dead-time compensation" feature specifically benefits brushless gimbal motors, eliminating micro-vibrations that plagued V2.0.
For First-Person View (FPV) pilots, every millisecond counts. The Mh-fc V2.2 firmware provides a noticeable improvement in "stick feel." The new error-handling routine prevents the dreaded "yaw spin-out" during aggressive throttle punches. Users report that the quadcopter feels more "locked in" during windy conditions due to the improved wind estimation algorithm.
