(8)replaced (power way down @ 18,000ASL, two plugs dropping out). Cost

Original message -------------- <BR><BR>> John, <BR>> <BR>> If I'm
flying in a full-scale, I like having the <BR>> redundancy of two
completely separate iginition <BR>> systems. :-) <BR>> <BR>> I'm
not sure what you mean about two plugs making the <BR>> troubleshooting
more difficult. Should be easy to <BR>> isolate. <BR>> <BR>> OTOH,
changing plugs on my Dad's 182 was an expensive <BR>> proposition. Back
in the 80's, each plug was $12, and <BR>> there were 12 plugs. :-( I have
no idea what they <BR>> cost now. I guess if you can afford the fuel now,
you <BR>> can certainly afford the plugs. The 182 holds 80 <BR>>
gallons! <BR>> <BR>> Bob R. <BR>> <BR>> --- John Ferrell
