Will,

Your impression is correct.
Some people say that the famous "Rotax" capacitor could replace the 
battery, but during our experiments on the voltage regulator, we found 
that in certain cases, it would not start - or continue - supplying 
power without having first a battery connected.
So with an electrically dependent engine, the Rotax suggested circuit is 
to be taken with a grain of salt.

I'll translate the detailed study within the next few weeks.

It would be interesting to ask those questions on the Aeroelectric List, 
where we meet builders of many horizons interested - and some very 
knowledgeable - in electricity.

FWIW,
