I absolutely love the Hiller upgrade. Being a newbie (got mine Christmas) I was afraid that it would be too responsive and hard for me to control - it turned out to be the opposite. It is now so stable that I can easily hover as long as I care to in my tiny den right in front of the TV. It used to be so slow to respond that I would usually get into an un-recoverable situation and have to land or crash it.. Now, just a slight request to move immediately translates into movement so it ends up staying pretty much right where you want it to. Outdoors, I can now hover it up to 50 ft w/ decent confidence. I used to get real nervous at 20 ft.

I screwed the pitch links all the way down and out about 3 turns and I put one of the spacing shims on each side.
