Hi Steve,

Fortunately, we are not cats.....curiosity is a good thing for our species. My decision to go with a dual electrical system had its genesis when I was pondering the practical continuous output from the integral Rotax alternator in the context of what I wanted to have on the plane to start with (day-night VFR); and, what I might add to the electrical demand later. Then other considerations started seeping into the decision; such as, a) just about every system failure I have had on an airplane has had to do with the electrical system, b) the 912ULS, I am told, isn't very easy to flip-start, c) we plan on a lot of extended cross country and back country airports (where electrons are harder to come by than in a metro 'port if you really need them). d) a little extra battery capacity is a good thing in Minnesnowta and Buuurmidji. On the other hand, considered the extra weight and $; but, I already jeopardized my children's inheritance during the build; and, I am kinda on the back side of the bell shaped curve for body weight anyway so I put the pounds in the airplane rather than changing my eating habits.

Sincerely,
