We are having trouble getting the AeroSky 550 hexacopter to fly. We purchased the ready-to-fly version, assembled it, and loaded MultiWii 2.2 on it using the Arduino IDE. However, the rotors do not spin when we attempt to arm the hexacopter. We have taken apart the body and determined that the wiring is correct. The voltage levels change on the receiver pins when we change the transmitter inputs, so we are sure that the transmitter is working. What could be the problem?


EDIT: We've also wired the ESC inputs directly to the receiver, and they do spin when the throttle is on, so it isn't a hardware issue. Does anyone know what might be wrong in our MultiWii setup? All we did was enable some of the #defines in the config.h file.
