I forgot to ask a question in my last post....
You know that spring that goes inside the spark plug cap on the end of the ignition module? I'm tired of seeing it laying on my workbench next to my plane or on the floor after I've had the cap off when working on my model for whatever reason. It always falls out. Then I have to remove the spinner, prop and cowl so I can pry the cap off the spark plug to put the spring back in big hassle.
So, is anybody running their DL without this spring? I asked this once before and got only one answer from Bob Pastorello who said I have to use it. He's the DL "guru" on this forum, but I was wondering if anybody has actually run their engines without the spring.
I'll hang up and listen for your answer.
Hi Tim,
Like you, I also think the spring is a pain in the butt, so I do not use it. Instead I soldered a wire to the metal cap and crimped an eyelet on the other end of the wire. Drilled a hole in one of the fins and attached it with a screw and nut.
If for some reason the metal cap looses contact with the spark plug because it has no spring, an electrical return ground path is still there. Electricity will flow from the spark plug through the aluminums head, through the wire attached to the fin and back to the cap, then continues to the ignition module as previously with the spring.
