Hi Ron
Yup! I'm the origional designer and buillder of the 40A
alternator off the crankshaft. The Rotax series engine is just not
capable of anything approaching what we want for electrical power. We
are all electrical hogs in our wants on the panel. I'm guilty as I now
have a Lycosoris with a 60A alternator and a back up of 8A on the vac.
pad. on my new build. We just have to reconcile our "needs" with what we
"want". Its the same as my new build for the emergency or just to get by
power source of 8A. What do you not "need". Part of the thoughts are
what will you need that requires so much power. I went with LED running
lights to reduce the power req. for night flight. Plus, landing lights
are needed for only a short time and thus can run off the battery for the
short time in the pattern. The game for Rotax drivers is to minimise the
electrical loads and still get the stuff you really "need" and have your
"AA" batterys for back up for the hand held transmitter and GPS. What
else do you really need? I know- just look at my new panel and see how
the pot is calling the kettle black! But I've been there with my Europa
and I used the 40A alt and used about 18 to 20 but it was because of the
strobe light system requirements. It would really hog the power when
charging the capacitors for the next pulse. The real key would be a
maker of strobes that used less power.

Hello Jim
"The real key would be a maker of strobes that used less power."
I am using Kunzleman strobes with a combo head. The 2 strobes I think draw
2 amps, and the LED position draws not much.
