Thanks for the insight, it all makes perfect sense.If you dont mind me
asking..... How long did it take for you to fullfill your A&P license?Thanks
again.

the electronic ignition in your car. But In aviation, you don't fly with the
complete harness as installed in a car. No matter how simple the electronic
ignition, they do have issues as well, whether fouling sensors from burning
leaded fuels, amatuer wiring issues, wear of moving parts or other installation
issues. My experience has been that while magnetos require proper care and
feeding to keep running properly, I have only experienced one complete failure
of a magneto in 3000 hours of flight. With a dual ignition system, that was a
non-event. My experience with electronic ignition in aviation is that I saw my
first failure in less than 100 hrs due to the failure of an edge connector on
the electronic ignition module. As an A&P that works on primarily Experimental
Aircraft, I have worked on a number of aircraft with nearly every type of
elecronic ignition sold for the experimental aircraft market. (EMag,
LightSpeed, EFII) They ALL have issues, and not a single one of them has been
a 100% trouble free, install it and forget it installation like what we all
enjoy in our cars. Thanks to the mass volume of production, the auto
manufacturers have most of the bugs worked out. By comparison, the units being
sold for aviation still have a lot of issues, as will any "one off" custom
installation. Having said that, I do run E-mags on my KR, and will eventually
convert my SuperCub over to the same. If it was financially palatable, I'd
love to convert over the fuel injection as well. But I don't see that
happening in the near future. I believe the blanket statement that the
electronic ignition is more reliable in aircraft vs a magneto fired ignition is
patently false if you are comparing aircraft installations rather than factory
auto installations vs magnetos. Jeff ScottLos Alamos,
