That looks about how I flew when I first go into decent hovering. As far as being out of control goes, it's more a stability issue with the CP, if it was rock steady like beiiger helis it would be a different story. If I were you I'd start head in soon, the longer you wait the hearder it will be. Trust me. I learned tail in, FF, and FFF, and some basic aaerobatics before realizing, hey, I gotta learn to hover this head in... how stupid is that! Then it's harder to learn because your always thinking, hmmm, this sucks, let's fly over there... and then there you are, not learning head in like you were supposed to be... Your doing good though!
