To follow up (and not start another thread) I thought I'd just add to this post...
... I've been flying my BlueRay 450 a couple of times per week recently and have been having a blast. This is really one nice helicopter. I've got the blades tracking perfect and the hover is very smooth. Also, it took some adjusting (and research) but I finally figured out the gyro and got the heading lock to work which makes nose in hovering much, much easier. Anyway, just thought I'd share some good news.
Happy Hovering
