The Flyduino features a 12 standard servo control capbility with an Xbee socket which can be used in model helicopters or UAVs via the Xbee link. The feather weight (7.5g) makes it an ideal controller for application with a limited payload. The built in regulator allows the input voltage to vary from 3.5-8V which fits most power supplies without any modification.
