If the failsafe is set to HOLD all positions then it is not possible for the servo itself to move on its own if there is a loss of radio control. That would leave either a problem on the transmitter side - pot glitch, encoder glitch, module pin failure (especially for Futaba transmitters - EVO's are not known to have any issues with the module pins), or a servo/power/mechanical issues on the aircraft. Did you look at the LED on the Nano when this happened? The LED will blink if there was a loss of power. We have seen cases where fast power glitches can cause servos to move to one end, especially analog servos, but the servo signal returning immediately corrects this. The power glitch can occur with just a single servo when the connector makes poor contact. Remember, servo connectors are only good for about 25 insertions/removals before you are suppose to throw them away and use new connectors.
