Todd, The cost of the CDI is 540.00 with a Good Mag ( no junk ) exchange. It does come with the two external coils & cdi module & brackets that mounts onto the top motor mount (not included) of the Bensen airframe. Comes with a kill switch also. No battery is required. Plug wires are availible for 20.00. Tachs are 2 1/4 at 150.00 / 3 1/8 160.00.
Here is some photos of the components. Photo shows optional fuel pump 39.00.
