When I upgraded to copter-3.6.5, my drone wobbled when it take off, so I decided to re-calibrate the radio and the ESCs. and when seeing the results in RC1_MIN and RC1_MAX, these are shown out of range. I did several tests and even though the same results are still presented, I wanted to go back to copter-3.6.4 but it is not shown in the mission planner.
