That aluminum hub should do the trick. Which supplier is that picture from?

Here are the two configurations that I think work out best for the Piccolo starting point

#1
Pic Fun - bearings - aluminum hub - CNC Anti Rotation Link
2 cell LiPo pack(s) and charger
CSM HLG200 HH Gyro
2 ESC (gws100 and gws50 OR 2x Pixie7P)

#2
Pic Fun - bearings - aluminum hub - CNC Anti Rotation Link
3 cell LiPo pack(s) and charger
Futaba gy240 HH Gyro
gws100 or pixie7P main ESC
schulze slim 105he tail ESC

Both of these configurations can let you swap out the main ESC and main motor for a brushless motor and controller. I used an Astro 010 (10T) and phoenix 10. Makes for a light, powerful heli. even on 2 cell LiPo power. I am never in a position where more throttle does not give me an instanteneous jump upward. (or sideways into the house) (or sideways into the tree) (or the fence) (or me) (gosh I wish I could fly better!) :-)
