Lynn,
   I've had zero problems with my Lightspeed unit other than a broken
connector to one of the coils (think we crimped it too tight and the wire
separated- one minute to fix) and a cracked sparkplug insulator.  Don't know
if the aluminum shield I put over it has any effect, but I haven't heard of
anyone else having trouble with these things.  Also, the unit is well
insulated; I have no EMI problems and unlike the first electronic unit I had
(an Electroair which was nothing but trouble) it doesn't even cause the
slightest blip on my Strikefinder.
   Good luck with your first flight,
