Or, maybe just a bit  myopic?


Being limited to only what I know now or can remember, I am myopic. I have  
a card that says I am.
 
The Utube movie proves the point. I cannot test the first coil because it  
died already. The penalty for a failure in the first 100,000 miles of an  
emissions part, is it is replaced free of charge. Since all of the failures 
are  not reported, it should be noted that the failures that are reported are  
the only source of data to establish anything. 
 
When I worked at Western Electric we produced pieces that had to be  
backwards compatible for 40 years.
Watch your young engineers faces go blank on the first day when you tell  
them that. You start by learning what was going on 40 years back. The life  
expectancy of all products except fuses was 40 years. Usually just acts of 
God  shut down phone systems. We could reproduce a complete central office 
from  drawings with the exact original equipment up to 60 years back. The new 
central  offices, about the size of a phone booth has to be able to dial in a 
call to a  1930s number one crossbar office in Sand Pile Egypt. They could 
modernize for  faster dialing speed and less modem noise, but hey, it all 
still works just fine  and they have no money anyway. Back in the day when 
your phone bill was $6.25  every month.
 
It is entirely possible to produce from available parts a damn near  
bulletproof ignition system. Putting electronics close to the fire of  
electromagnetic radiation, so you can reproduce the Charles Kettering system  seems to 
me a poor choice for aircraft use. 
 
Rotaries like a lot of ignition energy. Lighting a cigarette in a  
descending elevator (piston engine) is easy.
 
Lighting a cigarette while standing on top of your car a 60 MPH (a rotary  
engine) not as easy.
 
The plugs that Mazda gave us to race on, had a retracted tip design. (Ice  
cold). Both the ground electrode and the center electrode are fine wire. 
Nothing  to mask the start of the fire ball. NGKs with a 11.5 heat range. I 
forgot the  number. Its at home in Ohio. 
 
Trigger wires are antenna looking for transmissions from the plug wires.  
(Cross talk) Plug wires should be inductive like those found at the Hot Rod  
shop. They reduce electromagnetic radiation.
 
 The aircraft engine is run harder than a racing engine. The racer is  at 
WOT only about 70% of the time. Off the throttle for each shift up, and  
during hard braking. That is not the airplane case is it? WOT and load limited  
RPM will be the rule (once the cooling system is working).
 
Use the GM crap for the trailing plugs. You won't even notice when one  
dies.
 
Just another opinion. I could be wrong.
