Finally I did it in a couple of night!
It's amazing when dancing smooth criminal! Definetly love it.
I have lost some time because calibration.ino does not compile on arduino program but I solved with servohome.ino and trying different servo horn to find the position "zero"
The only "REAL" problem I'm stiil having is that I have to use both the usb cable AND an external power (7,4V lipo battery) because if not the arduino board continuosly reboot..maybe the futaba servos draw to much amps.....
Anyway is a super project!
