have anyone tried using copper plugs in rotary? how well does it work? I heard in turbo piston engines, copper sparkplug works alot better. it conduct electricity alot better than platinum. it last shorter, so i guess you gotta change them often, but then they are like $6 for a set of 4.

any experiences with copper plugs?

platnum conducts better then copper doesn't it? Conductivity increses as you go donw the series in the table of elements. From top to bottom it goes something like copper, silver, gold, then platinum.

I think copper will be ok as long as you change your pluhs often. I'm not sure though.

oops, checked the table, platinum is next to gold, so I dont know.
