Ok, tracking question. I'm seeing improvement in my skills with the sticks in keeping this baby a little more stable, but I've noticed a blade tracking issue tonight. I put it on the bench and got eye level with the 'disk' and put a different color tape on one of the rotors. Now I can tell (duh) which one is doing what. The one with the black tape is tracking higher than the red. So what makes that happen and how do I fix it? Hmm...maybe that one's actually in the manual, but it's more fun (and more educational) to ask here.
