Simple and elegant but no cigar for aircraft applications.  Using this

setup

you loose all power from one rotor in the event of a coil failure.
I'll put up with one more coil for the advantage of redundant

ignition.

Tracy what do you use to trigger your electronic ignition system?
Royce

Since I have been unable to find a single example of failed crank angle
sensors (2nd gen) after talking with every Mazda mechanic I could button
hole, I use the stock crank angle sensor.
If it ain't broke, don't fix it! :-)
