Ok, Since you are human I won't make fun of your ground strap if you don't make fun of my glider. I swear that fence jumped up a couple of feet!

Doesn't the sensor come with the ignition? Wouldn't you get that from the ignition manufacturer and not the engine manufacturer? Maybe someone in our club has an extra one. I think there is a guy that is pretty big on BME that we fly with. Why not check with him? He'll be at the meeting on Tuesday, maybe he'd bring you one. Probably quicker than calling BME
