I have a Hangar 9 Extra with a DA100 that I cannot get a good range test on. I have been through all of my radio components and can find nothing. I pulled the plug wires off and noticed that it does not appear that the wire in the plug boot would be touching the end of the spark plug when it is hooked up. I have attached a pic of the inside of the plug boot and you can see the wire way up in there but I don't see how it could be touching the end of the plug..Is this correct for a Da or am I missing something? Thanks. Rusty
