This thread is very timely for me, I was thinking the same thing (the SX about 4 feet back and the IRL510 right next to the Parallax, Melexis Digital Hall Sensor for my high energy TCI style ignition) In order for a TCI ignition to create a high voltage spark, it needs the coil supply voltage shut off very fast. The IRL 510 is fast at 15 ns according to the data sheet, [url=http://forums.parallax.com/forums/default.aspx?f=7&m=105106]But this old thread about sparks and the SX have also been a concern [/url]

The normal setup in a car would be with the sensor on the crankshaft and the controller about 4' to 6' away. But this is in one of my airplanes with an 80cc twin. The coil should put out better than 35 Kv and is easily twice the normal voltage output of the CDI systems used for RC Airplanes, so I was considering building a "Farraday Cage" for both the SX and the RC receiver with the antennae going out the back of the airplane.

Does anybody have any other ideas on how I can make this system work, in a truly delicate envionment and help keep from having a $5000.00 model airplane go SPLAT! (it has the latest 14 ch Futaba radio inside)

I am finishing up the ignition test stand today and I should be testing the ignition tonight or tomorrow.

Thanks 

Bill
