You have more flying time than me, but when I correct with the rudder mine was doing the same thing but I have pretty much concluded it is me. I believe my right thumb moves just enough to make it go in reverse.[]

No, I have been trying to work around this for two weeks, I know it's not me. I input a little more throttle and it still drops. Maybe 1 in 10 times when I do left rudder it will jump.
