Took my H for flight first time after upgrading firmwares, both the controller and the drone, to the latest version. Taking off and rotating the drone worked OK but no response to a right stick controlling movements (Mode 2 selected). The drone then started to drift over nearby bushes. And because I could only control altitude and rotation and wasn't able to return it to the takeoff field (tried Smart and Angle mode, no response in either), I turned a mode switch to a Return Home mode. That instantly killed motors droping the drone from 3m altitude on a rock breaking one landing gear and a gimbal mount. Any idea what went wrong with upgrades? Tested this on the ground without props and same thing: as soon you switch to the Return Home mode, motors dies. Not very good when that function should save your drone.
