You're getting closer.
Next thing is to make sure at half stick the swashplate, washout base arms, flybar control frame arms, blade grips and mixer arms are all level and parallel with each other. Otherwise you will never get linear movement and consistancy in regard to pitch.
What I said above is very important or you'll never get equal pitch on both blades throughout the collective range.
Maybe this will help, it gets good about 2 minutes in.
