  I went with the Aero-Electric Z-14 approach (two alts, two batteries).
  I rationalize that chances are slim that both alts will quit on the same
  flight, unless I break a belt and it takes out the second belt.
"""

Given the concern about the first broken belt removing the remaining one, I've 
often wondered why no one has suggested a sheet metal guard that separates the 
2 belts?  A flat sheet of .040 aluminum mounted to some brackets that were 
outside the perimeter of the belts with clearance holes for the pulleys would 
shield the belts from each other... there must be at least .250 or more 
between the belts.  Has anyone ever tried anything like this?
