I am working on a board that has a separate 12V and 5V switching
regulators for servos and an input for a battery for an autopilot and
servo battery backup.  Is this something that anyone else would want?
Vin for the board is about 50V  This would allow for the autopilot to
be used for much larger planes.. is this something anyone else would
be interested in?
