Have you purchased the heli yet?
If not, I have a Piccolo fun with all of the best upgrades for sale.
[link=http://www.rcgroups.com/forums/showthread.php?p=2840161#post2840161]Specs here[/link] Something like $210 plus shipping. More if you want the gy240 gyro.

If you have purchased the heli, I would recommend getting these upgrades:
CNC ARL (the stock ARL always twists on me)
Aluminum hub (holds the bearings on better)
Bearings
Ball-in-swash (or the lightweight aluminum swash that comes with BiS)

For the best performance, I would recommend ditching the mixing board and running separates:
3 cell LiPo
gy240 HH gyro
Whatever main ESC (Pixie 7p)
High frequency tail ESC (Schulze or TREC)
