I had a dual-ElectroAir ignition setup (of the 1998-2000 vintage; based on several conversations with ElectroAir not much has changed) installed on an angle valve 360.

Although they performed well while working (especially at higher altitudes), I had three failures in less than 50 hours of flying--two of which happened in flight and one on runup.  All of these were caused by a crank trigger failing and knocking out the rest of its system.

****DETAILS YOU CAN SKIP IF YOU DON'T HAVE AN ELECTROAIR SYSTEM****

The setup I had used two crank trigger housings mounted on the standard magneto drive pads.  These housings contained a toothed gear and small magnetic sensor module.  I kept replacing the sensor modules with new parts directly from ElectroAir, and they kept failing with no apparent cause.  It took me three times to figure out that the sensor modules are cheaply made, and they allow the guts of the sensor to drift out of their case and into the teeth of the pickup gear...no matter how well you secure them in the crank trigger housing.  My solution was to use high temp epoxy and reinforce where the sensor cable goes into the case in an attempt to keep the guts from drifting out of the other end...but I decided to replace the entire ElectroAir setup before I had a chance to test this.

****END DETAILS****

I would highly recommend you look at a different electronic ignition solution.  Check out the systems made by Robert Paisley of Protek Performance and http://www.flyefii.com.  He makes everything from a single electronic ignition system to a dual-ECU complete electronic fuel injection system.  All of them use an excellent sensor design.

Best of luck!
