Richard are you new to the Experimental aircraft movement? Electronic
ignition has been around for years and years and used successfully.

we would all love to have fadec systems for our aircraft. and electronic ignition. but it comes to a comfort factor. electronics fail in worse case mode 95% of the time. while mags when they fail tend to do so slowly and if you know what to look for you can find it before total failure.
the next problem with fadec type controls is lightnining, have a billion volts of electricity running thru your electronics, can cause a bad day. i have seen holes as big as 1/2 inch burned in to commercial airframes from this. but to be honest most just look like arc hits and can be drilled out with a 3/16 bit.
with proper burnin and testing electronic work great, but i don't have enough history with the E+P mags, to say which way i would go. i do know that this testing is expensive and it has taken slick and bendix many years to develope like type equipment. ie get it right enough to go to market. i like the idea i do not know yet if i like the approach.
So what would the great slick hater do if it was my aircraft. if i won the lotto i would buy a gulfstream and never have to worry about slicks again, but since this will not happen, and i don't have an extra 2400$ lieing around to change to bendix. inspection is the way to go. look at it and cleanup the carbon dust that will prolong the life of your mag more then anything else. figure 100 hr inspection include the mag for cleanup and inspection. if you start to see carbon tracking/ arc damage it is time to replace/repair. that is the time you should start thinking about replacement
i wish that could help you more with the e+p mags, but with my limited experience with them, i can only say that it is an idea whose time has come but lets see if they really work in the field.

About ten % of my work is experimental. and of that i would say that 20% have some type of electronic ignition. i just don,t have enough time on the systems to have a warm and fussy feelings for them. Maybe i am just a stick in the mud, but new is not always better. show me a system with 20yrs on it and 100,000 hrs. and then i will decide to recommend or not. since this is critical life support equipment, and none of the manufactures i have seen have published complete testing data, including esd/lighting, mtf, and age/enviromental relate degridation, i will just sit on the side line for now.

WOW - I thought I sent this to you privatively. And I must
agree with Jerry and conclude that you are new to
"EXPERIMENTAL" aircraft. I will stick with the
tried and true people like Sam B and others. I was just
"kicking the tires" on another source of
information. But I like the old hands the best.
Thanks
