If I remember correctly, I asked the hand propping question of the
E-Mag Ignitions folks at AirVenture a couple of years ago.
I think the response was to carry a regular 9V battery with you, since
it would be enough to get the plane started.
That information would need to be verified and the concept would need
to be tested, and you would need an elegant way to connect it, but if
you plan to be away from civilization, it might be an elegant solution.

Prevent
I removed the electrically dependent engine circuits from my previous posting.
Attached is a wiring diagram based on Z-19 but with the addition of a second
E-Bus relay. If the engine is started using only one of the batteries, the other
battery will prevent brownout of the avionics.

I was given the same information on my last
visit to Emagair . . .

What kind of microphones/headsets? Aviation
style? Over what distances are the wires
routed? The task is 'easy' . . . just
need some details on the hardware you
plan to use.

| Subject: | Re: OT-AA battery performance at low temp |
After further testing I don't think it is thermally degraded battery
performance. I believe the problem is being caused by contraction of
some part of the circuitry.
Any tips on looking for the failure point. Likely components, telltale
appearance of a connection, things like that.

The things we admire in men, kindness and generosity, openness, honesty,
understanding and feeling are the concomitants of failure in our system.
And those traits we detest, sharpness, greed, acquisitiveness, meanness,
egotism and self-interest are the traits of success. And while men
admire the quality of the first they love the produce of the second.
