Suzuki uses a very light and compact Nippon Denso alternator. It's internally
regulated and rated at 35 amps. It is used in the Geo Metro and Samurai. The
same Alt can be found on late 80's Toyota Tercells. This would be the perfect
unit to use as a backup spun by a model airplane prop.
BTW: (if I haven't missed the posting...) There was a good article, about a
year ago in Kitplanes. The author used a similar alternator, and adapted it
to accept a model airplane prop.
